The air in modern homes can hardly be called clean: it contains a large amount of dust, as well as a variety of toxins emitted by furnishings.
To combat this, air purifiers are designed, the various models of which are offered by the modern market for household appliances. In addition to a ready-made expensive device, you can also make an air purifier with your own hands, saving a significant amount on this.
What cleaners can be made?
Before you start developing a homemade air purifier, you need to determine what level of moisture is contained in the air in the apartment. This indicator should not fall below 30% and at the same time exceed 75%. You can determine the level of this parameter using a conventional psychrometer. If the moisture content in the room’s air mixture does not meet this norm, you need to make not just a device for air purification, but devices that, in addition to its main function, will also humidify or dry the air.
Depending on the humidity level of the air mixture, one of two types of cleaners can be made:
- for air mixture with a high moisture content;
- for dried air.
Dry device
To make a device for purifying air with a low moisture content, it is necessary to prepare the following materials:
- plastic container with a tight fitting lid;
- low-power fan, which is a good computer cooler;
- water, best distilled;
- power supply for the cooler - it can be ordinary batteries.
First of all, holes are made in the container lid to secure the fan. It should be noted that such a design must be fixed as securely as possible, otherwise the fan may fall into the water, which will lead to a short circuit.
Next, a small amount of distilled water is poured onto the bottom of the container - so that between the upper part of the liquid and the lower part of the cooler approximately 3 cm remains for safety reasons.
To ensure economical energy consumption, such a home-made device can be equipped with a relay that will turn off and start the purifier at certain predetermined time intervals. When assembling the electrical circuit in this case, care should be taken to ensure that the fan does not supply voltage exceeding its rated value.
Having installed the cover of the homemade appliance in place, the do-it-yourself DIY air purifier is ready. Turning it on, the air from the room will fall into the container, where it will be mixed with particles of water, moistening in this way. All harmful microorganisms and dust contained in it absorb water particles. As a result of all this, the air will become not only cleaner, but also humid.
In addition, the device can also be equipped with a carbon filter by installing it on a fan. In this case, it will be possible to provide even more reliable air purification in the house.
In addition, some masters advise putting a silver product on the bottom of the container to ensure the purification of water inside the container.
The device for moist air
The second option is a do-it-yourself air purifier for a too humid environment, when this figure is more than 60%. In this case, additional humidification of the air mixture is not required.
To make such a device, you need to prepare:
- a plastic container and a lid to it;
- low power fan;
- common salt;
- any porous material - gauze, foam rubber, cotton wool or something like that.
From the opposite sides, two holes are made in the container at different levels - one for installing the cooler, the other for passing the air mixture. The next step in creating a homemade cleaner is to install a fan on the first hole, and the selected cleaning material on the second. Salt is poured inside the container, which should be located slightly below the cooler and at the same time completely cover the filter with it.
The principle of operation of the device made is that the air entering into it passes through the salt, on the surface of which harmful substances and excess moisture from the air will settle. At the same time, a clean air mixture will be saturated with salt particles - chlorine ions with sodium. Passing through a porous filter, such a mixture will contribute to the destruction of microbes living in the home, thus providing double air purification.
It should be noted that, when making such a device, it is recommended to choose a low-power fan. Otherwise, salt crystals will constantly drum against the walls of the plastic container, thus creating excess noise.
Thus, we examined two main options for home-made devices that provide good air purification in the home. Of course, such simple instrument designs that can be easily done with one's own hands even without special skills from literally improvised means do not have a high level of efficiency in comparison with serious factory models.
But taking into account the difference in the price of the finished device and the total cost of the materials used for the homemade cleaner, any complaints are simply inappropriate.
