Everyone knows about the benefits of cabin filters. Their main task is to clean the air from dust, odors and, in some cases, from harmful bacteria. What if the basic filter of the car has expired, and it does not cope, but it’s a pity for a new one. Or you have a domestic car and, in principle, do not produce carbon elements of the air cleaning system for it. In this case, you need to do a little work.
Therefore, we will tell you how to make a cabin filter with your own hands.
What are
First you need to figure out what filters are. Surely every home has a jug with a replaceable cartridge for water purification. The main component in such cassettes is charcoal. Less commonly, they also use additional substances to soften water or remove excess impurities. However, these filters are quite noticeably different in price from the usual ones. In addition to water filters, there are air filters that should work to clean the air in the room. Most often they are installed in workshops with production, where toxic waste is possible. However, in our time in cities, these filters are also becoming a necessity.
The benefits of filters
Why filters are useful can be said for a long time. Their main function is cleaning. Whether it is water or air, or moonshine, the filter should, in the opinion of those who use it, remove all harmful and leave only useful. In fact, removing absolutely everything and immediately will not work. As a consequence, it is necessary to purchase devices with several cleaning stages. So what do the filters remove? Water-based ones mechanically remove dirt, pieces of rust from the water supply system, improve taste and quality, and fight against unpleasant odors, if any. Charcoal helps fight some living organisms that can be harmful to health. As an excellent natural absorbent, it is able to retain many harmful bacteria, but not all. Do not rely only on the miraculous properties of charcoal. For example, he is not able to neutralize radiation, remove heavy metals or salts. Using a filter to clean moonshine, it should be borne in mind that not all fusel oils will be completely removed.
Paper option
Making it as easy as shelling pears. To do this, you need to buy a universal filter from a kitchen hood in a store and cut a piece out of it to the size of the old one. Then glue it into the frame from the previous one using a sealant or hot melt glue.
Of course, the paper filter of the cabin is far from the best and it only copes with dust, letting in extraneous odors into the cabin.
Paper filter for your car's interior
Buy or make a filter
So, a purchased filter requires regular replacement with a new one. This is due to the fact that over time, dirt accumulates in the cassette, which will gradually seep into the filtered water and make it worse in quality than that coming from the water supply. Extra costs make you think about how to make a charcoal filter with your own hands. If you have the skills to make any devices, then you can think about assembling some kind of structure that will save the family budget and not harm your health. However, it is worth calculating how economical it will be.
Homemade inflow with filter
I seriously thought about the idea of making a normal inflow in the apartment. But the quality of the outside air is poor. That is, it somehow needs to be filtered. Break the Internet, I realized that the most suitable budget solution for me is the Sfera inflow with a photocatalytic filter: ">
It costs about 1200 bucks.But if you figure it out, it turns out that there is simply nothing to pay $ 1200 for. I found prices in the internet, where all the components (with wrapping) fit into 350 bucks, plus a very "fashionable" remote control for 200 bucks, and the rest of the cost is a case and a "fashionable" LCD indicator. In general, to ditch 1200 bucks is not for x. th just a toad crushes. And even more the toad presses that it is only on one room.
Then I got the idea - what if you buy a separate photocatalytic filter for 50-100 bucks (sold separately from the same manufacturer), a UV lamp for 40-50 bucks, a fan and mount it all somehow into a channel in the wall? (We will omit the issue of air heating for now). Will come out budgetary and efficiently. And the filters should be mounted either in the channel or on the outside of the wall in standard filter boxes. It is also possible to mount the photocatalytic filter itself in an external box. Tell me what? Should I bother? Who has any ideas?

Worth it! Bother. And most importantly, share your experience later!

Of course it's worth it. How else can you realize that even the hammer and sickle are not just pieces of iron, but objects of labor designed for your tasks.
Threat just all the same you will not succeed.

But why . Quite everything can work out and you need to "bother". Just don’t
akylinin wrote:. mount it all like that into a channel in the wall?
Because it will turn out to be pornography. It is necessary to make "your" body from "your" material, it is quite possible to plagiarize the appearance
This is my opinion and I do not impose it
I see that instead of a substantive discussion, pointless banter began.

and then patent, buy all certificates and opinions and sell with a margin of 500%. no, it is better to 450% so that competitors can recapture a segment of the market
.
But seriously, why fence your corps? The idea is such as to fit all this into the channel. Or in metal boxes outside the wall. For example: a filter box with an F5 filter, behind it a filter box with an F7 filter, then a self-made metal box (or an alteration from a filter box) with a UV lamp and a catalyst, then a box with an F7 or F9 filter (they don't seem to be installed anywhere, but confuses that the catalyst spraying may crumble over time - it is probably necessary to filter something), then a fan, possibly a silencer and inlet through a channel in the wall into the room above the heating battery. Air supply in the range of 40-50 cubic meters per hour. Screw the outer blocks to the wall on the brackets and paint with enamel. Cheap and cheerful.
Option number 2. I saw such an interesting pribluda on the Internet: "> The reviews on it are positive, and the manufacturer himself seems to be serious. In fact, this is a pipe made of a catalyst wrapped in a dust filter, and inside is a UV lamp, and two fans stick out on the sides (as people say, computer fans). Such happiness is worth 130 uyov. For components without a case from the same store - something about 80 uyv. The idea is to take all this and stupidly shove it into a channel in the wall and seal the joints (for example, blow out with polyurethane foam
). Even the standard fans can be left, just muffle the catalyst on one side, and turn the fan 180 degrees. And that's all. It may also be necessary to put a second cascade of a catalyst with a UV lamp in the channel, but these are already variations on the theme. Cheaper and easier than the first option.
What will come in handy
In order to make a charcoal filter with your own hands, you will need a container that is not a pity to donate for a good purpose (for example, a five-liter plastic flask), oddly enough, fine gravel, river sand, charcoal, as well as gauze, cotton wool and lutrasil. Some masters insistently suggest replacing cotton wool and gauze with synthetic material, for example, synthetic winterizer. This is due to the fact that synthetics are more durable, but at the same time, their filtering qualities are no worse than those of natural materials. In addition, a clerical knife, a drill with a thin drill, and sandpaper for cleaning irregularities are useful.
Clean water is the key to health
Getting started making the simplest water filter, you need to remember that it also has its drawbacks. Inexpensive materials will also have to be changed, and quite often. In addition, improper assembly of this design can lead to poor water quality. And this will nullify all the efforts made. If you still dare to make a charcoal water filter with your own hands, you need to start with the lid. You need to make several small diameter holes in it with a drill. Clean up irregularities. Then you need to cut off the bottom of the bottle. Next, inside the bottle, gauze, cotton wool or synthetic winterizer is placed on the lid. You can do everything at once, but this will not greatly affect the quality of the water, but it is capable of retaining water inside the filter.
It is desirable to separate the next layer from the previous one with an additional barrier. Some people use a coffee filter. Others suggest cutting a circle out of plastic so that it covers the previous layer, and making many small holes in it. After smoothing out the irregularities on the homemade mesh, you need to lay the coal. This can be activated charcoal from a pharmacy or self-prepared from birch wood. Such coal will definitely cope with its task and will not add unpleasant odors and harmful resins to the water. It is advisable to separate the next layer from the coal again, as it will be sand. Ordinary sand can mix with coal and permanently clog the filter, so it is advisable to use quartz. Next, gravel or zeolite is laid. On top, for the coarsest and most primitive cleaning, a cotton cloth is sometimes used. However, experts strongly recommend replacing natural fiber fabric with lutrasil. The first filtered water must be drained off, as it is not usable.
Such a filter is able to purify a small amount of water. Its main disadvantage is cleaning speed. And you won't be able to use this filter for a long time - it gets dirty too quickly.
Domvent: question-answer
Ventilation valve "DOMVENT" in the online store ECOTECO
I use warm floors as heating. Is it possible to install your ventilation valves?
Alexei.
Unfortunately, we do not recommend installing Domvent ventilation valves not above the battery, because at temperatures below -50C, condensation may occur on the body, and a cold floor zone may form under the valve. Work on the design of a device for ventilation of apartments with warm floors is underway, but so far not on sale. In cottages where the first floor has underfloor heating, and on the second floor there are radiators, we install Domvent ventilation valves above the radiators of the second floor. And for the first, we can recommend you to put wall KIV or window Aereko.
Good day! When cold air from the street meets warm air in the room, condensation will fall out. Where will it drop? And won't a fur coat grow in the pipe of the supply valve, and then flow out onto the facade in the summer?
Boris.
As you have noticed, condensation falls out in the place where cold and humid warm air meet. In this device, this place is in the air above the battery, therefore, condensation does not form.
The second possible location: on the surface of the device. But condensation does not form there, becausethe unit is washed by a warm stream from the battery and is also insulated from the inside.
The third place for the formation of condensation: inside the tube - it is impossible, because You yourself noticed there is no second condition in it: warm, moist air.
Only cold dry air comes from the street. And since with properly functioning ventilation, air only goes inside, we have considered all the options with you.
In case of improper installation (for example, not above the battery), the heating is turned off, etc. condensate may fall on the surface of the valve, which is eliminated by closing (or decreasing) the valve of the indoor unit.
Thanks for the question.
Do any of the window installers put your valves right away when replacing them?
Yes, they do. It is convenient, and there is a good additional income for window workers. Window companies installing our ventilation valves can be found on the Internet or advertised in the media.
And if my A4 sheet sticks to the ventilation grill even when the bathroom door is closed, do I need a valve on this door?
Adhesion of the sheet shows that there is traction in the ventilation duct, and the grilles in the doors are needed for sufficient air access from the apartment to the bathroom. If there is a sufficient total gap between the door and the box for air passage, then the valve can be omitted.
On your website it is written "Our masters, coming to the installation, first of all check the operation of the exhaust ducts and in case of poor performance, either immediately fix the problem, or, if it is not immediately possible, give recommendations on how to solve the problem." How can you check the operation of the exhaust ducts yourself? How can you determine in advance whether a door valve will be needed, or if you can get by (and what will happen if you just do not close the door)?
Ventilation check:
Open the window and door in the bathroom, apply A4 sheet to the exhaust ventilation grill. If he "stuck", then everything is fine. If not, then:
We tear off a fine-mesh mesh from under the grate (which gets clogged in two weeks with dust and therefore does not let air through (and, in principle, is not needed), if there is a fan, then we buy a double grate (part of the grate, part of the space for the fan) so that the air passes through into the ventilation duct and with the fan off.
We call the management company (ZhEK, HOA, etc.), they must fix it for free.
Compared to an open door, the door valve is more comfortable (maintains silence); instead, you can put simple door grilles or a gap under the door of at least 1 cm.
If the door is not closed, then when you, for example, wash, all the moisture (all steam) will go into the apartment and increase the humidity in the entire apartment, which is not good for the home climate. Yes, and it will not be very comfortable for you to wash, and the children will sleep at this time.
If there are grilles at the bottom of the closed door, air from the apartment will enter the bathroom below and humid steam will be discharged into the ventilation grill at the top, but will not go into the apartment.
In the kitchen and toilet, the situation is similar for all points.
Is your system suitable for a private house or cottage?
Nina Alexandrovna, Vsevolozhsk.
Dear Nina Alexandrovna!
For a country house, our system is ideal, because any house has exhaust ventilation, as well as stoves and fireplaces, which also work to remove stuffy air. For a comfortable stay, only 7-10 Domvent ventilation valves are needed per cottage (they are easily installed in one day). They do not make noise, which is especially important in suburban living, and will please you with the cost in comparison with complex systems.
Can a ventilation system be installed without drilling a hole in the wall?
Maria, St. Petersburg.
Dear Maria!
The Home ventilation system, like any other natural ventilation system, works according to the following principle: it starts up fresh outside air and removes the polluted inside air into the ventilation mines. Therefore, an inflow of fresh air from outside is necessary, i.e. opening to the street is required.
But don't let that scare you, becausetoday, this operation for drilling a hole by an experienced craftsman takes 5-10 minutes (the entire installation of the Domvent ventilation valve will take about an hour) and, practically, without dust, this is permitted by law and does not pose any threat to the supporting structures.
Explain how to calculate how many DOMVENT valves are needed for adequate ventilation in the room?
Alexey, St. Petersburg.
Dear Alexey!
The DOMVENT ventilation valve is placed under each window of the living quarters (first in the rooms, then, if necessary, in the kitchen). Under normal operating conditions, one valve is enough for 15-17 m2 of a room. But if you have a lot of people or not very good natural draft (for example, the last floor), then you need to install two ventilation valves. Only then take into account the size and power of the battery. For a one-room apartment, we recommend at least 2 houses (or two in a room, or one in a room and one in a kitchen). If you are in doubt, send a description of your apartment and we will help you.
Please tell me which tool is needed for self-installation of the DOMVENT valve, and how is the installation carried out?
Sergey, Moscow.
Dear Sergey!
The installation process is straightforward. You can install the DomVent valve using a household perforator (SDS-Plus). You can see the step-by-step installation process and our recommendations here. If you are going to start a business or launch a new service for the installation of DOMVENT ventilation valves, then you will need to buy a larger perforator (SDS-Max) and a pair of 40mm diameter drills. Details here and here.
Hello, are you wondering if it is possible to purchase a valve from you, and do the installation yourself? And how, in this case, is it delivered?
Alexey, Rostov-on-Don.
Tell me, can the installation of such a valve cause drafts?
Albina, St. Petersburg.
Dear Albina! No, he can not! The fact is that the air volume of 13m3 / hour leaving the DOMVENT ventilation valve, unlike open transoms, heats up all on the battery and rises warm up and in no way can create a draft.
Can I install your Home Ventilation if I live on the 1st floor and is it not dangerous? Will all the exhaust gases from cars go to my apartment?
Valentina Ivanovna, St. Petersburg.
Dear Valentina Ivanovna! Quite the opposite, replacing open windows with the "Home Ventilation" system will make your apartment impenetrable for thieves.
And the DOMVENT ventilation valve will hold back poplar fluff, insects, part of the dust and constantly airing your apartment, will not allow harmful substances from furniture, building materials to accumulate in it and, which is very important for the first floor, will not allow odors and harmful substances rising from the basement to accumulate!
Hello, please tell me, will it turn out that, along with the air, midges and insects will get into my apartment?
Alena, St. Petersburg.
Dear Alena! A mosquito net is built into the construction of the noise absorber, which will protect you from insects and poplar fluff. By removing the cover once a year (for example, when washing windows) with one finger (even with wet hands), you can easily remove the muffler and shake it out or even wash it. It will take 1 minute of your time.
How long will it take to install one such window valve and how many window and door valves will need to be installed for a 3-room apartment (we have 4 windows and 4 doors, one for each room)?
Mikhail, Kolpino.
Dear Michael!
Installation of one valve takes about an hour, the old foundation takes a little longer. For a standard three-room apartment, it is necessary to install three DOMVENT valves in the living rooms (you can also install them in the kitchen as an additional one). DOORVENT door valves must be installed in plumbing doors (toilet, bathroom) so that moisture and odors are immediately discharged into the ventilation mine, and not into the apartment.And in all living rooms.
But if there are gaps under your doors (at least 1 cm), then the installation of the DVERVENT ventilation valves is not necessary. If the living conditions in your apartment differ from the standard ones (many people live, the kitchen is a place for gatherings and is tightly closed by a door, etc.), then it is better to consult with professionals or call us by phone.
Why drill a hole in the wall when you can just buy a window with a valve?
Vasily, St. Petersburg.
Dear Vasily!
We do not like to scold our competitors, because they also do a wonderful job - they save people from problems with stuffiness. Therefore, we will talk about the advantages of DOMVENT.
Firstly, the air entering through the DOMVENT valve immediately heats up and enters the room warm (and there are no drafts, even in severe frosts!).
Secondly, the DOMVENT damper does not reduce the window light opening, does not violate the window warranty, and protects against noise much better (you will be very quiet!).
Thirdly, with comparable technical characteristics, DOMVENT will be half the price.
Fourthly, DOMVENT can be delivered at any time (before renovation, after renovation, during or after window installation).
Fifth, any person and even a three-year-old child can handle the maintenance and cleaning of the DOMVENT ventilation valve!
Can your ventilation regulate the room temperature and keep it cooler when I need it?
Alexander, Shlisselburg.
Dear Alexander!
During the heating season, the HOME VENTILATION system will supply cold air to the heating radiator and you can regulate the room temperature by reducing the air flow with the damper. And if your battery has a heat regulator, then you can achieve the ideal climate in each room individually. In summer, you need an air conditioner to cool the fresh air. And the combination of Home Ventilation and Air Conditioning is ideal as they complement each other. DOMVENT delivers fresh, oxygenated air, and the air conditioner cools it, and does not drive cold CO2 around the room, as in the absence of ventilation.
Can you buy a valve in gold color or somehow hide this box? The curtains do not hide it - we have Roman blinds. Thanks in advance for your reply.
Olesya, St. Petersburg.
Dear Olesya!
Ventilation valve DOMVENT is made of window ABS plastic, which can be easily painted even from a simple spray can. You can do this yourself or we will help you if you choose the tone of paint you need. The DOORVENT door valve has 4 grille colors (gold, bronze, silver and white) and is matched to the color of the door handles. In the case of non-standard colors, We can choose the color you need or also paint.
Please answer the question, our neighbors made repairs at our house and blocked all the ventilation outlets for us, will your device help in this situation? There is simply nothing to breathe in the apartment! Thank you.
Ivan Nikolaevich, St. Petersburg.
Dear Ivan Nikolaevich!
In such a situation, you need to contact the management company (or housing cooperative) serving your house with a request to eliminate the poor work (or non-work) of the ventilation shafts. And housing cooperatives must find out the problem and fix it (not you and your neighbor, but they themselves). Otherwise, file a lawsuit against the housing cooperative. Without normally working exhaust ducts, the work of Home ventilation will be ineffective.
Our foremen, coming to the installation, first of all check the operation of the exhaust ducts and in case of poor performance, either immediately fix the problem, or, if it is not immediately possible, give recommendations on how to solve the problem.
Often there is a situation when the residents of the house installed a ventilation grill with a mosquito net (they are sold in a set), which in 2 months becomes densely clogged with dust and stops letting in air. Cleaning or removing this mesh usually solves this problem.
Is it necessary to install the valve just above the battery? I have 7 cm places there. Will it fit?
Sasha, St. Petersburg.
Dear Sasha!
Yes! Installation of the DOMVENT vent valve is required above the battery. In some cases, it is possible to install a supply pipe above the pipes (as in your case) with air supply to the battery. The second option is to slightly lower the battery. There are several more options for solving this moment. You need to watch the master on the spot.
How much does installation work cost?
Installation Ventilation valve "DOMVENT" - 1000 * rubles. for 1 valve (* with a wall thickness of more than 60 cm and complex installation - 1300 rubles for 1 valve)
Installation in the door "DOORVENT" - 500 rubles. for 1 door
High-quality painting in any color according to the RAL catalog - 1500 rubles.
Departure of craftsmen within St. Petersburg - 500 rubles.
Departure of masters in the Leningrad region - 500 rubles. + 20 rubles / km. (outside the ring road)

DOMVENT delivers fresh, oxygenated air, and the air conditioner cools it, and does not drive cold CO2 around the room, as in the absence of ventilation.
Can you buy a valve in gold color or somehow hide this box? The curtains do not hide it - we have Roman blinds. Thanks in advance for your reply.
Olesya, St. Petersburg.
Dear Olesya!
Ventilation valve DOMVENT is made of window ABS plastic, which can be easily painted even from a simple spray can. You can do this yourself or we will help you if you choose the tone of paint you need. The DOORVENT door valve has 4 grille colors (gold, bronze, silver and white) and is matched to the color of the door handles. In the case of non-standard colors, We can choose the color you need or also paint.
Please answer the question, our neighbors made repairs at our house and blocked all the ventilation outlets for us, will your device help in this situation? There is simply nothing to breathe in the apartment! Thank you.
Ivan Nikolaevich, St. Petersburg.
Dear Ivan Nikolaevich!
In such a situation, you need to contact the management company (or housing cooperative) serving your house with a request to eliminate the poor work (or non-work) of the ventilation shafts. And housing cooperatives must find out the problem and fix it (not you and your neighbor, but they themselves). Otherwise, file a lawsuit against the housing cooperative. Without normally working exhaust ducts, the work of Home ventilation will be ineffective.
Our foremen, coming to the installation, first of all check the operation of the exhaust ducts and in case of poor performance, either immediately fix the problem, or, if it is not immediately possible, give recommendations on how to solve the problem.
Often there is a situation when the residents of the house installed a ventilation grill with a mosquito net (they are sold in a set), which in 2 months becomes densely clogged with dust and stops letting in air. Cleaning or removing this mesh usually solves this problem.
Is it necessary to install the valve just above the battery? I have 7 cm places there. Will it fit?
Sasha, St. Petersburg.
Dear Sasha!
Yes! Installation of the DOMVENT vent valve is required above the battery. In some cases, it is possible to install a supply pipe above the pipes (as in your case) with air supply to the battery. The second option is to slightly lower the battery. There are several more options for solving this moment. You need to watch the master on the spot.

Down with smell and smoke
The next item that often worries city dwellers is air purification. It is still very difficult to find such a device on the free market. So again you have to think about how to make a charcoal filter for air with your own hands. If it is available, for example, in the hood, then you need to see if it is disposable or reusable. If it is reusable, then it will be enough to open it, remove the used charcoal, rinse thoroughly, dry it and add new filler. If it is disposable, you will have to buy a new one or assemble a charcoal filter for the hood with your own hands.
All components are assembled again. It can be a standard hood for a hood, into which a structure of two mosquito nets connected to each other is inserted with activated charcoal poured between them, worn out to the state of granules or powder, depending on the density of the mesh. Some people suggest using sieves with metal meshes of different diameters. Charcoal should be poured into a sieve with a larger diameter, pressed with the bottom of a sieve of a smaller diameter and well secured with a sealant. And install this structure into the hood body. The peculiarity of such a filter is that the density of its absorbent will have to be adjusted according to the power of the exhaust fan. Since a layer that is too thick and dense may not allow enough air to pass through, and a thin and thin layer will not cope with its cleaning functions.
How to make a charcoal filter for ventilation with your own hands can be guided by the following instructions. For its manufacture, two pipes of different diameters, plugs, mesh, agrofibre and coal are used. Holes are drilled in the pipes. Then each is wrapped with mesh and agrofibre. The inner pipe is installed exactly in the center of the plug and secured with glue or other means. The larger pipe is installed later and also secured. Coal is poured between them. It remains only to put on one more plug on top. The filter is ready.
DIY ventilation in the apartment (5)
It's been ten days since I started up my air handling unit. Thanks to its use, dust is no longer visible on the windowsills. Also, I have never smelled any diesel passing by. All this suggests that the filters against dust and odors work perfectly!
Inspection of the filters of the supply unit after ten days showed that their condition is by no means ideal. The coarse EU4 filter got the most. He was literally wearing a dust coat. The EU7 fine filter is also not new in appearance. There are no crusts of dirt on it, but it has lost its snow-white color inside. Maybe partly due to the activated carbon in the previous filter.
Coal in a cassette can apparently serve for a long time. There are no smells from him and he looks the same as he was. During the operation, the layer of coal poured into the cassette was not disturbed in any way. It is uniform, as it was formed during backfill.
I vacuumed the coarse filter cassette and put it back. I have a powerful vacuum cleaner, thanks to which the cassette was cleaned quite well. Of course, you cannot clean it forever. You will have to hurry up with the purchase of filter material for replacement. With my ecology outside the window, apparently, I will have to watch the coarse filter once a week.
After these results, I am very pleased that I have installed an EU4 and EU7 filter in my air handling unit. Separately, one and the other filters would not be justified here. The first is not good enough in terms of the degree of filtration, and the second would clog very quickly without the first. Together, these two filters are the very thing.

Clean as a tear
How to bypass the filtering of a Russian folk drink in this thread? You can make a charcoal filter for cleaning moonshine with your own hands by analogy with a water device. The principle of operation is the same. Moonshine is poured into an inverted bottle with absorbents embedded in it and passively decanted into a prepared container. However, the sand and gravel will have to be removed in this case.
To clean the moonshine, experts recommend buying special coal. It is made from birch wood or coconut by pyrolysis and is capable of retaining a large amount of fusel oils. However, when collecting a charcoal filter for moonshine with your own hands, you need to take into account that plastic in this situation plays the role of an oxidizer. It is better to use a glass container or stainless steel flask for this purpose. Better yet, purchase a ready-made filter. In terms of costs, it is not much different from a homemade one. But there is much less hassle with the collection of the necessary materials.
Air supply to a private house
In order for supply ventilation to work in a country house, all the above methods are suitable. The exception is medium and large cottages or those houses in which a boiler is used for heating, taking combustion air from the room. Here we are talking about high air flow rates, local installations will not be able to provide it. A calculation should be performed and supply ventilation should be installed, which will supply air masses to all rooms. For this, stationary air handling units are used.
There are a large number of schemes and methods for placing equipment and organizing air exchange. The simplest of them provides for an inflow device in the main corridor or hallway. Taking advantage of the fact that the entrance hall is connected with almost all rooms, it is possible to supply heated and purified air into it, which will spread throughout all rooms of the building. But first, it is necessary to calculate the flow rate of air masses for the inflow. To do this, you can use the method described above, but the air flow for the boiler operation must be added to the result. If the house has local exhaust fans, then their performance should be included in the calculation.
Summing up all the costs, you can select the equipment.The issue is solved in two ways:
- Buy separately a fan, filter, heater and automation devices and assemble ventilation in a separate room.
- Purchase a ready-made supply unit assembled, then the ventilation device will consist in its placement and supply of air ducts.
Home appliances protection
Making a charcoal filter with your own hands is quite simple. If you need to filter out a little water for drinking or a little more in reserve, then this seems real. But protecting home appliances with homemade filters is not yet possible. More durable materials are needed for this scale. A plastic bottle will definitely not work, as well as a PVC pipe. In this situation, you will have to rely on specialists who have developed and manufactured functional structures that can protect home appliances from dirt in the water.
Summing up
So, making a charcoal filter with your own hands is not difficult. Anyone can handle it. However, this method should be used as a last resort, since such devices, made at home by inept craftsmen, can do more harm than help with water purification. The desire to save money and save the family's budget can lead to more tangible costs in case of possible poisoning with water passed through such filters.
