Clean air is vital to our health, but are you breathing in air that is clean enough? Even inside the house, the air quality cannot meet standards safe for people with allergies or respiratory diseases, for there could be smoke, pet hairs, dust, or other particles in the air.


Why We Need Air Purifiers?


According to the U.S. Environmental Protection Agency (EPA), indoor air pollution is five times that of outdoor air. It is because the lack of good circulation inside the room creates a favorable environment for airborne pollutants, which can increase the possibility to make us occur respiratory infections, neurological problems, asthma, and more problems. A powerful air purifier can reduce the risks greatly.


How to Choose an Air Purifier?

What is CADR? CADR means Clean Air Delivery Rate. The larger the CADR number listed on the air purifier, the more particles the filter can remove from the air. Generally, a larger room would require a larger CADR value correspondingly. Most of the time manufacturers will suggest the recommended room size on the packages.

Many manufacturers would mark noise levels on the packages. Choosing an air cleaner with little noise is important if you are going to stay in the room with the cleaner for a long time. Being exposed to noise pollution can be as harmful as air pollution. Generally, air purifiers with a noise level of 50 dB are suitable for most residential spaces., just like a modern refrigerator, it makes about 50 dB that is acceptable for most people.
