The information below will focus on room air purifiers (called air purifiers for short).

The mechanism of action of the air purifier

There are two types of air purification mechanisms that air purifiers can apply: passive air purifiers and active air purifiers.

Passive air filtration mechanism

Passive air filtration is a method of using filters to purify the air. With this mechanism, the air purifier will use exhaust fans to draw air from the outside environment into the machine. After that, the air will be passed through the filter to clean and then returned to the external environment.

With passive air filtration mechanism, the filter usually consists of many different types of filters made from materials such as foam, fiberglass, cotton . Each type will have the effect of eliminating pollutants. based on the size or nature of that agent. Common types of filters include:

1. Coarse filter : Has the function of filtering large size dust, animal hair, hair, small insects, some types of pollen.
2. HEPA filter : Has the function of filtering dust, mold, pollen . with sizes as small as 0.3 micrometres.
3. Activated carbon filter : Has the function of filtering exhaust gas, smoke, unpleasant smell .

Air cleaners may have different types of filters.

Active air purification mechanism

Active air purification is a method that uses air filters without filters that apply a number of other technologies such as:

1. Ionization : The air purifier releases negative ions and ions to contaminate the pollutants, thereby preventing them from floating in the air and sticking to the surfaces around the room. and can be easily cleaned by vacuuming, sweeping, and cleaning.
2. Electrostatic precipitator : The air purifier also electrically pollutes the air pollutants, then drains them with a charged plate.
3. Generating ozone : Air purifiers create ozone to eliminate air pollutants.
4. Thermodynamic disinfection : Air purifiers apply heat treatment to harmless pollutants. The air from the external environment is directed into the machine through convection, then goes through the ceramic core of microscopic capillaries heated to 200 degrees Celsius to burn the contaminants.
5. Ultraviolet sterilizing irradiation : The air purifier will use UV rays to kill bacteria, specifically removing microorganisms such as bacteria, viruses, mold.
6. Using photocatalyst cleaners : Air purifiers will use ultraviolet light in combination with catalysts (usually titanium dioxide - TiO ₂ ) to create chemical reactions that oxidize bacteria, viruses, molds, odors, volatile organic compounds into harmless byproducts.

The construction of an air purifier

Air purifiers on the market today can use either passive or active air purification mechanisms or both at the same time to enhance air filtration efficiency. Depending on the type of filtering mechanism applied, the principle of operation of the air cleaner may have different specific structures.

For example, for an air purifier that only applies a common passive filter mechanism, there will be three main components: the frame, the fan and the filter. With an air purifier that only applies active filtering mechanisms, the structure will consist of the main components of the chassis and the reaction unit (such as ion generation, photochemical reaction, UV emission . .). For an air purifier that applies both active and passive filters simultaneously, the structure of the machine will consist of the main frame, the fan, the filter and the reaction unit.

Features of air purifiers

In addition to the basic function of air purifiers, dust filters are also equipped with many other utilities such as deodorizing, bactericidal, fine dust filtration, creating negative ions, reducing static electricity, removing effects. cause allergies, moisturize, dehumidify, catch mosquitoes . to help purify the indoor air more effectively, bringing a fresh and healthy atmosphere to the user.

Along with advanced features, the air cleaner also has additional types of dust sensors, odor sensors, humidity sensors, air quality indicators, filter replacement warnings, etc. timer, sleep mode, power saving mode, child lock, remote control, display screen, intuitive control panel system . so that users can use the machine conveniently , easier.
