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, different models of which are offered by the modern household appliance market. 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 you make?
Before you start developing a homemade air purifier, you need to determine what level of moisture is in the air of the apartment. This indicator should not fall below 30% and at the same time exceed 75%. You can determine the level of such a parameter using a conventional psychrometer. If the indicator of the moisture content in the air mixture of the room does not correspond to such a norm, you need to make not just a device for air purification, but devices that, in addition to their main function, will also humidify or dry the air.
Depending on the moisture level of the air mixture, one of two types of purifiers can be made:
- for air mixtures with high moisture content;
- for dried air.
Device for dry environment
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;
- a low-power fan, which is a good choice for a computer cooler;
- water, best of all distilled;
- power supply for the cooler - these can be ordinary batteries.
First of all, holes are made in the container lid to fix the fan. It should be noted that such a structure 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 into the bottom of the container - so that about 3 cm remains between the top of the liquid and the bottom of the cooler 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 cleaner at certain predetermined intervals. When assembling the electrical circuit, in this case, care should be taken to ensure that the fan is not supplied with a voltage exceeding its nominal value.
Having replaced the lid of the homemade appliance, the do-it-yourself indoor air purifier is ready. By turning it on, the air from the room will enter the container, where it will mix with water particles, thus moistening. 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.
Additionally, the device can also be equipped with a carbon filter by installing it on the fan. In this case, it will be possible to provide even more reliable air purification in the house.
In addition, for heightened effect, some masters advise putting some kind of silver product on the bottom of the container, which will ensure the purification of the water inside the container.
Wet air device
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:
- plastic container and lid to it;
- low power fan;
- ordinary salt;
- any porous material - gauze, foam rubber, cotton wool or something similar.
In the container, on opposite sides, two holes are made at different levels - one for installing a 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 into the container, which should be slightly below the cooler and at the same time completely cover the filter.
The principle of operation of the device made is that the air entering it passes through the salt, on the surface of which harmful substances and excess moisture from the air will settle. At the same time, the 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 unnecessary noise.
Thus, we considered two main options for homemade devices that provide good air purification in the home. Of course, such simple device designs, which can be easily made with your own hands, even without special skills, literally from improvised means, do not differ in a high level of efficiency in comparison with serious factory models.
But if you take 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.
