DIY air purifier

The air in modern apartment buildings is not clean, it contains many different particles: dust, microorganisms, bacteria, pet hair, particles of clothing, etc. It is harmful to human health. Contaminants must be removed from the air. To do this, you do not have to buy expensive installations. You can assemble an air purifier with your own hands. Such a device will be inexpensive, simple and effective.

Types of Cleaners

According to the type of method used for air cleaning, the device can be divided into 2 types:

1. Designed for rooms with dry air.
2. Suitable for rooms with humid air.

In the first case, water is used as a filter. Due to its evaporation, additional humidification. Therefore, in damp rooms, such a device is not recommended to be used - air humidity will only increase.

The second type of device uses an absorbent, for example, simple edible salt. This substance is hygroscopic, which means it absorbs moisture from the environment. Therefore, when using this type of purifier, the air will be dried.

Before proceeding with the assembly of the cleaner, it is necessary set the degree of humidity in the room. The optimal level is from 40 to 60%. If this indicator is lower, then the air must be humidified, if higher - dried.

So, the use of a cleaner will allow not only to remove pollutants from the air, but also help to make the microclimate in the room more comfortable for its inhabitants.

Cleaner for apartments with dry air

To assemble such an installation is very simple. To do this, you will need:

• deep container with a lid;
• a small fan of low power, a cooler for a computer is quite suitable;
• water, better purified, filtered or distilled;
• fasteners for fan / cooler;
• power source, for example, batteries;
• sharp knife or other cutting object.

Step-by-step air cleaner manufacturing

Progress:

1. In the lid for the container, you need to cut a hole for the size of the cooler. The fan should be tight.
2. Fix the cooler. Suitable size screws or special glue can be used. The fan must be carefully fixed, otherwise it may fall into the water, which will lead to a short circuit and its failure.
3. Pour water into the container so that it does not reach the cooler. For safety reasons, 3-5 cm should remain before the fan. Then there will be no risk of water entering the device contacts.
4. Close the container with a lid with a fan.
5. Connect the cooler to a power source. When choosing, you need to consider what voltage it is designed for: a 12-volt fan can not be directly connected to a home outlet.
6. A properly assembled cleaner will work immediately when turned on. You can also make a device that automatically adjusts the fan operation time. But this is already at the request of users.

Do not leave the device turned on all the time, because this can lead to excessive moisture. Periodically, the water in the container must be changed or refilled as it evaporates. To monitor the water level and its degree of pollution, it is better to use a transparent plastic container.

To enhance the cleaning properties of the device, you can use a carbon filter, which is mounted on the fan. And if you put a silver object in the water, the air will be saturated with silver ions.

Wet Air Purifier

If the humidity level in the apartment is highthen the water installation will not work. Due to excessive dampness, mold or fungus may appear in the room. Therefore, it is necessary to use a dry substance as an absorbent. To create such a cleaner you will need:

• a plastic container with a lid, it is desirable that its depth is not less than 20 cm;
• fan with low power or variable speed, the impeller should rotate slowly;
• salt;
• gauze folded in several layers, cotton wool, foam rubber or other porous material;
• power supply for the fan;
• fasteners for cooler;
• instant universal glue;
• sharp knife.

Step-by-step purifier manufacturing

The assembly instructions for the purifier will be as follows:

1. In the container, you need to cut 2 holes on the walls opposite each other, but at different levels. The fan hole should be higher. The second, located on the opposite wall, is lower and smaller in diameter.
2. Fix the fan in the place intended for it.
3. Make a filter of porous material a little larger than the second hole. For example, cotton wool or foam can be wrapped in several layers of gauze folded.
4. Fasten the filter with glue or tape.
5. Pour salt into the container so that it covers the hole with the filter, but does not reach the fan.
6. Connect the fan to the power source and turn on the device at low speed. Otherwise, the crystals will knock on the container, creating a constant unpleasant noise.

The intake air will pass through 2 filters: a porous material that traps larger particles, and through salt that collects excess moisture, bacteria, and finer dust. Also, the air will be saturated with chlorine and sodium ions.

As it becomes soiled, the porous filter will have to be changed. Salt, absorbing moisture, will condense, cake. It will also need to be periodically changed.

Almost everyone can assemble an air purifier with their own hands. This does not require special knowledge and skills. This is a very simple and useful device.
