What is an air purifier? Is the air purifier harmful?

In the face of increasingly serious air pollution, everyone wants to stay in the air fresh environment, and the air purifier can clean the indoor air very well, so it gradually becomes a common indoor electrical appliance, then what is an air purifier ? Is the air purifier harmful? Let's take a look at the decoration home decoration network Xiaobian.

What is an air purifier?

Air purifiers, also known as "air cleaners", air purifiers, purifiers, are capable of adsorbing, decomposing or converting various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc.) , bacteria, allergens, etc., products that effectively improve air cleanliness, mainly divided into household, commercial, industrial, and building.

There are many different technologies and media in the air purifier that enable it to provide clean and safe air to the user. Commonly used air purification technologies include adsorption technology, negative (positive) ion technology, catalytic technology, photocatalytic technology, superstructure photomineralization technology, HEPA high efficiency filtration technology, electrostatic dust collection technology, etc.; material technology mainly includes photocatalyst, activated carbon, synthetic fiber. , HEAP high-efficiency materials, negative ion generators, etc. The existing air purifiers are mostly compounded, that is, a plurality of purification technologies and material media are simultaneously used.

Is the air purifier harmful?

The air purifier uses a green and environmentally friendly way to filter, adsorb and decompose various pollutants in the air, but as a household appliance, it is the same as the household appliances such as TV sets and induction cookers in our home. If the air purifier is from a very professional point of view, there is a little bit of radiation, because as long as it is an electric appliance, there will be electromagnetic radiation. This is unavoidable. The key is the magnitude of this radiation value. The damage to the human body is very small, and it can be neglected. When using it, we can refer to the method of use so that radiation can be effectively avoided.

The radiation of the air purifier can be said to be minimal, and when we use the air purifier, it is usually used in the corner of the room, so the radiation is negligible for pregnant women or children, the air purifier is Anti-static and anti-radiation aspects are in place. There is a special anti-radiation electrostatic protection film, which can effectively reduce the radiation intensity and anti-static protection system. It is suitable for families with pregnant women, children and the elderly.

The traditional air purifier uses the filter intercepting method to purify the air. The purifying principle is to use the built-in fan to extract the air, the air is pumped, and the filter is mechanically filtered. When the dust collides against the filter net, the layer is blocked. Large particles of dust are trapped in the filter. Professor Chen said that the current filter-type air purifier on the market does not play a role in PM2.5.

The harm of the traditional air purifier is not limited to this. It is not only unable to fully effect the 3-state pollution, but also because of the high-speed operation of the fan, continuously exerting a strong suction force on the filter screen, and blowing some of the pollutants passing through the filter mesh to the air again. Produce secondary pollution. The strainer is susceptible to mold and mildew, and is sent to the indoor space with a hair dryer. Some models with electrostatic dust are prone to produce ozone, nitrogen compounds and other derivatives during work, which is not worth the candle.

The above is what Xiaobian brought to you. What is an air purifier? Is the air purifier harmful? I believe that everyone has a basic understanding of air purifiers after reading this article.
