Recently, the pollen season has come. Many friends say that the "air purifier" is an artifact, which can effectively reduce the pollen rate in the room and relieve the discomfort caused by hay fever.
But in fact, research has found that not all air purifiers are effective! We checked some information and found that there is also knowledge in it.
Let's first look at what air purifiers actually do and how they work: in simple terms, it contains a filter and a pressure pump that forces air into the filter and then releases the filtered air. During this process, particles are deposited into the filter, which cleans the air in the room.
Donna Green, who works at the UNSW Centre for Climate Change Research, said not all air purifiers were effective at filtering pollen.
The best option is an air purifier with a HEPA (High-Efficiency Particulate Air) filter. HEPA filters are capable of removing up to 99.97% of dust, pollen, mold, bacteria, and other particles in the air, down to 0.3 microns.
So, if you have black mold in your home, or babies with asthma or pollen [allergies], be sure to check for HEPA filters when buying an air purifier!
In addition to filtering PM2.5, air purifiers with HEPA filters can also capture air containing COVID virus particles, which can be used to help remove the virus from the air, experts say.
Now everyone knows how to choose the right air purifier for you!
