Review on TRUSTECH 215ft² Air Purifier for Home, H11 HEPA Filter, Removes 99.97% Allergens, Smoke, Pollen, Pets Hair, 20DB Desktop Air Cleaner, 3-Stage Filtration, Air Quality Sensor for Office, Bedroom (White) by Kimberly Bryant

for a long time for suitable air purifiers and when I saw them, I was attracted by their description. At the very beginning I had doubts about their functionality. But now I have to say it was better than I expected. I brought them to put one in my daughter's room and the other in my room. Their size and other aspects look like the picture. I thought their 3 stage filtration system really got rid of odors and pet hair because the air quality is better than before. HEPA air purifiers have 3 fan speeds and they can automatically adjust the fan speed based on the ambient air quality, which is good for my daughter as she doesn't have to think about which mode to be in. And its easy operation is convenient for my daughter. The HEPA air purifiers sleep mode was great. My daughter and I can have a good rest when they are still working. Also, I always think about the environmental problems that these household appliances will cause. And HEPA air purifiers surprise me because they are 100% ozone free. Air purifiers are environmentally friendly and improve my quality of life. So far it has exceeded my expectations.
