How to choose the ten-faced squatting air purifier?
Under the smog, China's air purifier market sales share soared, becoming the world's third largest air purifier sales market. The performance, appearance and price of the air purifier are very different, which makes it difficult for consumers to have a dazzling feeling when purchasing an air purifier. How to choose an air purifier? What should I pay attention to when purchasing an air purifier? Which air purifier is suitable for my current situation? Do you understand these? Let us take a look at the following content.
What kind of suits me?
The air purifier mainly does three things: removing dust particles, killing bacteria and viruses, and removing formaldehyde benzene.
First of all, determine whether there is formaldehyde pollution in your own room, if there is, then it is recommended to buy a strong ability to remove formaldehyde, many foreign brands of air purifiers are basically ineffective for formaldehyde (no formaldehyde after the renovation), of course, there are many products now For the special purpose of China, it has added the function of removing formaldehyde, so pay attention to it when buying! If there is no decoration pollution (or you think it is not serious), then the core function is only to solve dust and bacterial viruses.
For dust particles: activated carbon adsorption, electrostatic dust collection, HEPA high efficiency filtration.
For bacterial viruses: active oxygen, low temperature asymmetric plasma air purification.
For the reaction of formaldehyde benzene, there are: molecular complexation and photocatalytic catalytic decomposition. In addition, negative oxygen ions are specifically for secondhand smoke.
Remember: not every new technology you need!
Secondly, I want to know if additional functions are needed, such as increasing humidity, increasing negative ions, increasing oxygen, etc. Personally, these functions are chicken ribs.
Finally, considering the cost of post-maintenance, the regular replacement of filters and additives, the replacement of consumable parts, and the warranty service are all costs.
Be prepared to buy which ones are necessary
Air output: A good air purifier must be fast, that is, the air volume is large. It is expressed by the (m3/h)cadr value in the product manual. The larger the value, the better.
Purification efficiency: Select products with high purification efficiency, specifically the removal rate of solid particles, the removal rate of volatile organic compounds, and the removal rate of formaldehyde. These three indicators are usually expressed as a percentage, and the larger the value, the better.
In addition, the filter is the core purification device of the air purifier, so pay attention to it.
