Due to the continuous increase of haze weather in recent years
PM2.5 values in many cities frequently explode
In addition, the smell of formaldehyde, etc. is strong when purchasing furniture for new house decoration.
to breathe clean air
More and more people are starting to buy air purifiers
So do air purifiers really work?
Of course the answer is yes!!!
The air purifier can detect and control indoor air and decoration formaldehyde pollution, and bring fresh air to our room.
which includes
1) Settling particles in the air, effectively settling dust, coal dust, smoke, fiber impurities, dander, pollen and other inhalable suspended particles in the air to avoid allergic diseases, eye diseases, skin diseases and other diseases.
2) Remove microorganisms and pollutants in the air, effectively kill and destroy bacteria and viruses in the air and on the surface of objects, and at the same time remove dead skin flakes, pollen and other sources of diseases in the air, reducing the spread of diseases in the air.
3) Effectively eliminate peculiar smells, effectively remove strange smells and polluted air from chemicals, animals, tobacco, oil fume, cooking, decoration, garbage, etc., and replace indoor gas 24 hours a day to ensure a virtuous cycle of indoor air.
4) Quickly neutralize chemical gases, effectively neutralize harmful gases emitted from volatile organic compounds, formaldehyde, benzene, pesticides, misted hydrocarbons, and paints, and at the same time achieve the effect of alleviating physical discomfort caused by inhaling harmful gases .
So, can air purifiers really eliminate PM2.5?
Air purifiers have become a must-have household appliance for haze prevention in many families. They play a significant role in indoor air purification. They can detect and filter PM2.5 in the air and effectively protect the respiratory health of family members. In haze weather, indoor anti-haze air purifiers are indispensable.
Are air purifiers effective in 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 permanently solve the formaldehyde problem, 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 seriously, then the treatment cannot be completed. The air purifier is an auxiliary means. It is recommended to open it 24 hours a day, which has a certain effect on formaldehyde removal.
So which air purifier has the best haze removal effect?
Most air purifier filters are composed of HEPA filter and activated carbon filter. HEPA is mainly used to purify solid pollutants such as dust and PM2.5, while activated carbon filter is mainly used to absorb volatile gases such as formaldehyde and odor.
To make indoor air quality meet a certain clean standard, there are two necessary conditions.
First, it is necessary to ensure that the indoor air reaches a certain number of ventilations, that is, the fan built in the cleaner is required to have a certain air volume.
Second, the primary purification efficiency of the cleaner must be relatively high. Clean air volume (CADR) is a physical quantity that can quantitatively characterize the above two necessary conditions of a cleaner.
Generally speaking, 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 whether an air purifier is excellent, but note that this is not the only or dominant indicator.
