DIY air purifier

The principle of operation of a do-it-yourself air purifier for the home, which anyone can make, is the same as a commercial device - polluted air passes through the device (a filtration system or a single filter) and the cleaning process occurs.

How a homemade air purifier works

Some filters may use atypical, rare additions to purification - air ionization, treatment with infrared radiation, and others. Such additions are considered unitary (highly specialized) and only partially enhance the effect of cleaning using the standard method.

DIY device manufacturing options

Anyone can make a filter for air purification with their own hands. You just need to decide in advance about the conditions in which it will work and choose the filtration filler that is suitable for you.

DIY air purifier for dry rooms. Dry rooms are rooms where the humidity is less than 30%. It is very important to try to increase the overall humidity level, and in no case reduce it. Take a small water container and fill it halfway.

Place a computer cooler or fan that runs at low speed at one end of the container.Secure the “air supply system” so that it cannot get into water - this can lead to a short circuit in the electrical network. Thanks to the interaction (penetration) of air with water, it is purified, and the process of increasing humidity also occurs. You can pour hot water into the container, thus saturating the entire room with steam.

For wet rooms. It is better not to additionally humidify wet rooms (humidity level more than 60 - 75%). For an air purifier, instead of water, as described above, you can use standard kitchen salt.

The properties of salt allow it to absorb moisture and clean. To prevent the salt from flying away from the air flow, it should be covered with gauze or any other material that would prevent it from breaking into small grains.

With carbon filter. You can make your own purifier with a carbon filter if you have a sufficient amount of activated carbon. Place the coal inside the container and make small holes in it (you can use a corner).

The "fan" should be placed so that it blows air out of the container rather than blowing air into it. Next, you need to cover the container with a cloth so that the “fan” blows out only the air that can enter through the small holes where the coal is located.

Important! For greater efficiency, such a purifier can be raised so that it is easier for it to take in air from the bottom of the container. Coal does not affect indoor humidity in any way.

Rules for using the device

1. The device should not be too noisy; loud noise indicates difficulties with the air supply (the engine “chokes” and begins to operate at high speeds).This may also indicate an unsuccessful fastening of the fan itself.
2. The filtration media must be changed periodically; Don't forget about it! A homemade filter will not be able to personally remind you of this procedure! It is recommended to set a notification on your mobile phone about the date for replacing the filter media.
3. Try not to leave homemade air purification devices unattended. Any electrical appliance (especially a homemade one) requires special vigilance and care when operating it and, if possible, should not be left unattended. As for homemade air purifiers, they must be supervised throughout the entire period of their operation.
