Air purifiers: who needs them?

Home air purifier is a compact device that allows you to create a healthy microclimate in the room. It effectively removes dust, smoke, pollen, pet hair, harmful allergens, volatile organic compounds, including formaldehyde, and other contaminants from the air. This is especially important for people with allergies, asthma and other respiratory diseases, as well as for those who care about a healthy atmosphere at home.

Types air purifiers

All devices can be divided into several types, depending on the filter inside the body. The simplest devices are with plasma filters. Their principle of operation, the following - inside the body there are two plates, which under the action of electricity create a static field. It attracts the microparticles, purifying the air. The advantage of such devices - the low price, it is not necessary to buy new filters, the plates are washed and installed back. It is important to understand that due to the one-stage cleaning, the devices may not work effectively in dusty rooms.

HEPA filter is a special finely porous material, folded into an accordion, which detains the smallest particles. The air driven by the fan through the filter becomes clean at the outlet. The filter should be cleaned once or twice a month, and replaced annually for a new one. These devices clean well, plus they are inexpensive because of the simple technology.

EcoQuest Air Purifiers have a more complex design, where the air goes through several stages of purification. A fan draws in the air and first removes large particles of dust.

Then ultraviolet disinfects it. After that, the purified masses fall between electrostatic plates that attract finer dirt. In the last step, the ionizer saturates the air with charged particles, which is beneficial for the body.

This is a great option for children's rooms, but you should pay attention to the noise level of the device. As in the previous type of purifiers, in this one there is no need to change the filter, the plates are washed, and everything else is cleaned with a vacuum cleaner.

In photocatalytic purifiers, the air, after passing the primary filtration, enters the chamber, where it is irradiated with ultraviolet, and is treated with a special catalyst. It converts harmful substances into harmless ones: oxygen, water and carbon dioxide. Devices of this type clean the air so effectively that in addition to harmful microorganisms remove neutral. Therefore, in the process of using it, it is necessary to follow all the tips and recommendations that are listed in the instructions.

In purifiers with ozonation function, the air goes through several stages of purification, but the final stage will be passing through a voltage converter, which creates static electricity. Such a device copes quite well with the task, but periodically it must be turned off so that the ozone concentration was normal.

Separately carbon filters in air purifiers do not use them. They are additional and can be installed in any device. They detain coarse dust and also neutralize odors. The main drawback is that they need to be replaced every six months. Also, they do not tolerate moisture and when wet, the filter will caking and ceases to perform its functions.

How to choose

Before you buy it is important to correlate the area of the room with the volume of air to be cleaned. Consider whether you will be moving the device to different rooms or it will stand permanently, for example, only in the nursery. Or maybe you even need a model with a wall mount. Some additional functions might be useful, such as an air quality measurement, a night mode in which the device works with minimal noise and does not disturb your sleep, or a special allergen program that actively neutralizes pollen from plants and animal hair. It is convenient to use the cleaning intensity regulator.
