Residents of large cities are faced with the problem of high levels of various air pollution. Dust, dirt accumulate in the dwelling, pathogenic organisms appear. This leads to the appearance of various allergic diseases, fungus on interior items and other negative consequences. Airing cannot solve all the problems. Therefore, special devices that can significantly improve the indoor microclimate have appeared on sale.
Wanting to save money, you can make an air purifier with your own hands. With a responsible attitude to their work, it will turn out to make equipment with improved operational characteristics.
Principle of operation
Creating a do-it- yourself air purifier for your home, you need to evaluate the indoor climate. Today, there are various devices that eliminate dust, fluff, allergens, unpleasant odors (such as tobacco smoke), as well as chemicals.
The air that is in the room passes through the device. The contaminants that are in it settle on special filtering materials. On sale today a wide selection of HEPA filters, plasma, coal, ionizing devices are presented. There are also photocatalytic devices and air washers.
The cost of such devices is quite high, and the design is sometimes so primitive that homemade filters are more effective. Therefore, many owners of apartments and houses decide to assemble a cleaner themselves.
Medium type
When creating an air purifier for an apartment with your own hands , first of all, you should decide what level of humidity exists in the room. For this, it is better to use a special device. Humidity should be between 30 and 75%. If the indicator does not fall within the specified range, people living in an apartment or house may have health problems.
If the air is too dry, the filter must have the ability to humidify. It is also called a sink. In this case, a method of evaporating cold water is used. The indoor microclimate is normalizing. In this case, pollution and allergens will be removed from the air.
If the humidity in the room is more than 60%, you will need a device that will not use water in its design. Equipment, on the contrary, will remove high humidity.
If you need to quickly eliminate cigarette smoke in the room, chemicals floating in the air should use a charcoal filter.
Dry Cleaner
When considering how to make an air purifier with your own hands , you should start with a category of devices called sinks. In the heating season, the risk of overdrying air increases. Radiators, convectors, stove heating, etc. contribute to the rapid loss of moisture. Therefore, equipment such as a filter wash should be used.
To create this equipment, you will need to prepare a capacious container made of plastic, a computer cooler or a small fan, as well as distilled water. The system will operate on a network. Therefore, you will need to prepare a power supply for the fan.
A hole for the cooler is cut out on the lid of the container. It should be fastened with screws. The design must be reliable. If the cooler falls into the water, a short circuit will occur. Several holes should be made on the top of the container. Water is poured into the pan so that it is at least 3 cm from the fan. The electrical circuit is assembled and connected to the network. The device will absorb impurities in the air, making it cleaner.
Humidifier
Creating an air purifier with your own hands, you can use water as an absorbent. This approach has been considered above. However, for rooms with a humidity level above 60%, this approach is not suitable. The use of water in this case will be impractical. In a humid microclimate, a fungus is formed, pathogens. Therefore, such air, on the contrary, should be dried.
In this case, the filter element may be salt.
It absorbs excess moisture well. If the surface of sodium chloride is covered with a porous material, such a device will be able to clean the room from dust.
The design of such a filter also involves the presence of a fan with a low rotational speed of the blades. Two holes are made on the sides of the container. One of them has a fan. The other should be located on the opposite side a little lower and have a smaller size. It is covered with porous material (you can use gauze). The salt is poured into the container so that it completely covers the bottom hole covered with gauze. Salt should not reach the fan.
Principle of operation
Creating a dry-type air purifier with your own hands , you should choose low-power fan models. Otherwise, the salt will be in suspension. She will beat against the inner surface, creating a noise.
The air will be sucked in by the fan and pass through the salt. Dust will also settle on it. Sodium and chlorine ions will be sent to the environment. This will help to remove pathogens and fungi.
Carbon filter
If you want to assemble an air purifier from smoke with your own hands , coal should be the main active ingredient. It is able to eliminate harsh, unpleasant odors in the room. It is used together with a fan (selected in accordance with the dimensions of the room).
For the manufacture of the body, you can take plastic pipes with a diameter of 200 and 150 mm. Length and size are cropped. Holes are made in the inner pipe with a drill and drill (15 mm). The drill may become dull in the process.
30 mm diameter holes are also made in the outer pipe. The distance between them should be 5 mm. The large pipe is covered with agrofibre. Then it is wrapped with a masking net and clamped with clamps. The protruding agrofibre must be cut with a blade. The same procedure is performed with the inner pipe, but first you need to put on a paint net, and agrofiber on it. The edges should be treated with aluminum tape.
Mugs are installed in the plug that remain after drilling. One pipe is put into another. Coal is poured inside. The design is put on a fan.
Having considered how to make an air purifier with your own hands, everyone will be able to do all the work quickly and efficiently.
