Before I purchase anything, I compare all products and read reviews. Reviews do matter and are a part of my decision making process. Deciding on an air purifier was a bit time consuming because there are so many out there that provide a wide variety of options to suit different needs.
This is the first time I purchased a Whynter product and was pleasantly surprised.
It truly does clean the air!
While in the auto mode:
When my dog walks past it, it kicks on! He's "bad air".
When I sweep, it kicks on! Dust is "bad air".
It kicked on when I picked up my dirty laundry and the machine got a whiff of it. Dirty laundry is, "bad air".
If you want good air, this machine will clean the bad air and distribute the good air.
I like the low amperage rating, the UV light feature, and the replacement filters are priced reasonably at this time.
