FAQ

functions : It can adsorb, decompose or convert various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, allergens, etc.). Features: Air purifiers are used in home, medical, and industrial fields. Home-based household air purifiers are the mainstream products in the market. The most important function is to remove particulate matter in the air, including allergens, indoor PM2.5, etc., and also solve the problem of indoor and underground space and airborne volatile organic air pollution caused by decoration or other reasons. The use of air purifiers to purify indoor air is one of the internationally recognized methods for improving indoor air quality due to the persistence and uncertainty of the release of air pollutants in relatively closed spaces. Extended data: How the air purifier works: The air purifier is mainly composed of a motor, a fan, an air filter and the like. The working principle is as follows: the motor and the fan in the machine circulate the indoor air, and the polluted air passes through the air filter in the machine to remove various pollutants. Or adsorption, some models of air purifiers will also be equipped with a negative ion generator at the air outlet (the high voltage in the negative ion generator generates DC negative high voltage when working), the air is continuously ionized, a large amount of negative ions are generated, and is sent by the micro fan. Form a negative ion airflow to achieve the purpose of cleaning and purifying the air. 1, passive adsorption filter purification principle (filter purification class): The main principle of the passive air purifier is to use a fan to pump air into the machine and filter the air through the built-in filter, which can mainly filter dust, odor, toxic gas and kill some bacteria. The filter screen is mainly divided into: a particulate filter and an organic filter. The particulate filter is further divided into a coarse filter screen and a fine particle filter. , 2, active purification principle (no filter type): The fundamental difference between the principle of active air purifier and the principle of passive air purging is that the active air purifier is free from the limitations of the fan and the filter screen, and is not passively waiting for the indoor air to be pumped into the purifier for filtration and purification. It is an effective and active release of the purification and sterilization factor into the air. Through the characteristics that the air will diffuse, it will reach the corners of the room and clean the air without dead angle. 3, double purification class (active purification + passive purification): This type of purifier combines the technology of passive purification with the technology of active purification.

The principle is that the air purifier sucks in the dirty air and is removed after passing through the internal filter. According to the power of the fan, the space of the filter screen is arranged. If the wind is too strong, the air discharged through the filter will be contaminated. Inhale air again and pass through the filter to remove contaminants to the greatest extent possible. In principle, air purifiers can be divided into two types, one is the principle of passive adsorption filter air purification. The other is the active air purification principle. 1. Passive adsorption filter air purification principle The passive air purifier mainly uses a fan to pump air into the machine, and then filters the air through the built-in filter to filter dust, odor and disinfection. Filter air purifiers mostly use HEPA filter + activated carbon filter + photocatalyst (cold catalyst, far catalyst) + ultraviolet disinfection + electrostatic adsorption filter to deal with air. 2. Active air purification principle The principle of active air purification differs from the principle of passive air purification. The active air purifier is free from the limitations of the fan and the filter. It is not necessary to wait until the air is pumped in and then filtered and then discharged through the fan. Effective and active release of purification and sterilization factors into the air, through the characteristics of diffuse and diffuse in the air, to achieve the effect of no dead angle purification of air in all corners of the room.

1. New house in addition to odor The family decorating the new house will always smell an unpleasant smell. In fact, this is the formaldehyde substance in the adhesive among the large amount of wood and decoration materials in the renovation of the new house. Formaldehyde is used in the production of adhesives. Urea-formaldehyde resin, urea-formaldehyde resin is the main substance among the decoration material adhesives, but the urea-formaldehyde resin is not stable, and it is easy to volatilize formaldehyde in case of high temperature. Compared with traditional window ventilation and plant removal of formaldehyde, the air purifier has stronger strength in addition to formaldehyde, which can accelerate the adsorption and purification of formaldehyde. 2. Clear indoor particles A lot of particulate matter is hard to see by our naked eyes. The common PM2.5 is a substance that is invisible to the naked eye. In fact, there are many small particles in the enclosed space. The performance is obvious. A lot of dust will appear in a room that is not cleaned for a while. In fact, this is the precipitation of floating objects in the air. If the air purifier is activated for a long time to effectively adsorb and intercept these invisible particles, the air in the room is cleaner and the frequency of cleaning the indoor space can be reduced. 3. Protect respiratory health In recent years, the incidence of respiratory tract in China has risen sharply, which has a great relationship with environmental changes, and the overall quality air quality of indoor space has also declined. The popularity of air purifiers is also a great guarantee for the respiratory tract, especially for weak constitutions. Both the elderly and the children can play a good role in protecting them.
