Due to the continuous increase of haze weather in recent years
Many cities PM2.5 values frequently burst table
Plus new home decoration, purchase furniture, formaldehyde, etc.
In order to breathe clean air
More and more people are starting to buy large room HEPA air purifier
So is the air purifier really useful?
The large room HEPA filter air purifier can detect and control indoor air and formaldehyde pollution, bringing fresh air to our interior.
1) Settling particles in the air to effectively settle various inhalable suspended particles in the air such as dust, coal dust, smoke, fiber impurities, shavings, pollen, etc., to avoid causing allergic diseases, eye diseases, and other diseases.
2) Remove microorganisms and pollutants from the air, effectively kill and destroy bacteria and viruses in the air and on the surface of objects, and remove dead dandruff and pollen from the air to reduce the spread of diseases in the air.
3) Effectively eliminate odor, effectively remove the strange smell and polluted air emitted from chemicals, animals, tobacco, oil smoke, cooking, decoration, garbage, etc., and replace indoor gas continuously for 24 hours to ensure a virtuous circulation of indoor air.
4) Rapidly neutralize chemical gases, effectively neutralize harmful gases emitted from volatile organic compounds, formaldehyde, benzene, insecticides, aerosol hydrocarbons, and paints, while at the same time reducing the discomfort caused by inhaling harmful gases.
So, can the air purifier really eliminate pm2.5?
Air purifiers have become a must-have home appliance for many families. They have a small role in indoor air purification. They can detect and filter PM2.5 in the air and effectively protect the family’s respiratory health. In the smog weather, the indoor anti-mite air purifier can not be less.
Is the air purifier effective for removing formaldehyde?
First of all, we must understand that formaldehyde is produced by decoration and raw materials, and it cannot be removed for a long time. To solve the problem of formaldehyde permanently, it is necessary to remove the pollution source of the decoration or raw materials from the source. Otherwise, it can only be treated by formaldehyde, but if the formaldehyde exceeds the standard, then the treatment can not be completed. The air purifier is an auxiliary means, it is recommended to open 24 hours, which has a certain elimination effect on formaldehyde.
So what is the best way to remove air purifiers?
Most of the air purifiers are composed of HEPA filter and activated carbon filter. HEPA is mainly used to purify solid pollutants such as dust and PM2.5. The activated carbon filter is mainly used to adsorb volatile gases such as formaldehyde and odor.
There are two necessary conditions for indoor air quality to meet certain cleanliness standards.
First, it must be ensured that the indoor air reaches a certain number of air changes, that is, the fan built in the cleaner has a certain amount of air.
Second, the purification efficiency of the cleaner must be relatively high. Clean Air Volume (CADR) is the physical quantity that quantifies the two necessary conditions above the cleaner.
In general, the larger the CADR value, the higher the purification efficiency of the purifier. That is the clean air output ratio, which directly affects the purification efficiency. The higher the CADR value, the higher the purification efficiency of the purifier and the larger the applicable area. It can be seen that CADR is an important indicator to measure the excellence of an air purifier, but note that this is not the only or dominant indicator.
What should I pay attention to when purchasing an air purifier?
The brand, function, performance, design, and price of the air purifier are very different and dazzling. Consumers are advised to purchase products according to their actual needs, not as many features as possible. For example, for consumers who need to protect PM2.5, it is recommended to choose an air purifier with an outstanding PM2.5 purification capability. Newly renovated homes can focus on air purifiers that have outstanding formaldehyde and toluene capabilities.
At the same time, when purchasing, try to choose a big brand, the quality will be more secure.
