Air purifier: how it works and when you need it

In large cities, air quality leaves much to be desired. Dust, smog, and other pollutants can easily cause allergies, shortness of breath, or simply make you feel unwell. You can solve these problems with the help of technology: an air purifier will help you here. What is this device, how does it work and who will need it? We will talk about this in detail in this article.

What is an air purifier
Many people still understand the massive units installed in all kinds of industries as a cleaner. But reality is different. The range includes dozens of models for apartments and houses. The most compact of them are comparable in size to fan heaters. There are also more massive devices comparable in size to the indoor unit of the air conditioner. They can also be hung on the wall. Such models usually have high performance.

As you might guess from the name, the main task of this technique is air purification. Its effectiveness depends on the type and complexity of the filtration system. Most models cope with the removal of dust, allergens, animal hair, various microorganisms, mold, and unpleasant odors from the air. The most advanced models have an efficiency of up to 99.98%. They trap particles down to 0.1 microns in size. Most of the devices are powered by 220V.

Design, principle of operation and functionality
Most purifiers are designed the same way. Inside the case there is one or more fans responsible for blowing in and blowing out air. Most of the space is occupied by the filtration system. This can be a set of filters, electrostatic plates or a water filtration unit (it all depends on the specific model). The case has special grilles for the passage of air. The controls are usually located on the front panel.

The principle of operation of the cleaner is simple. Fans blow air into the interior, it passes through the filter system and is blown back.

The degree of purification depends on the set of installed filters – we will talk about them below. In some models, there are nodes that improve the performance of the cleaner.

Ionizer . A special element that ionizes air flows passing through it. Light ions “combine” with harmful substances, blocking them. In particular, ionization will help eliminate allergens.
Ozonator . Purifiers often use special ozone generators. This chemical compound is a powerful oxidizing agent that is used for sterilization. Ozone allows you to suppress the development of microorganisms and get rid of unpleasant odors.
Humidifier . If the purifier has a special flask for water, most likely, the gadget is also capable of acting as a humidifier.
Flavoring . The device can use cartridges or aroma capsules with essential oils, creating a pleasant aroma in the room.
Remote control. Some devices require control from a remote control and a smartphone. These models have a radio module, an IR sensor or Bluetooth.
When to Use an Air Purifier
First of all, residents of large cities will need an air purifier. This is especially true for those living in an industrial area or near roads. The maximum allowable concentration of harmful substances in some cities has been exceeded many times. According to the IQAir service , the Krasnoyarsk Territory is the leader in Russia in terms of pollution.

An air purifier is also useful in small towns, especially for residents of houses near parking lots, car services, and industrial enterprises. If you live near chemical industry facilities, look for models with a quality HEPA filter.Air purifier Xiaomi Mi Air Purifier 3H white
