Dang this this is awesome. I read some other reviews and though they were excellent reviews they did say there was a smell to it. but I just came home after being evacuated from the creek fire in California and my house smells so bad I am so happy to smell this clean air that has been improved from this air purifier. It worked overnight in one room and about 3 days for the whole house.
We keep buying Alen air purifiers because of the great job that they do in cleaning out the air. You can prove this by taking a look at the used filters. During the Covid virus the add a protection to ones family.
We had evacuated from the fires and a friend had this filter from years ago to help keep down allergens from their pets. It did amazing when the air quality was terrible outside. And while the fires are done for the summer we are ready for next summer now, for better or worse.
I purchased a FIT50 to hep reduce the smoke particulate levels inside our house's master bedroom from the ubiquitous California wildfires. (When outside PM2.5 levels are high, AQI>150, and there's an in-out temperature gradient, infiltration into the house is inevitable, even with HVAC house filters w/MERV ratings>13.)
We were very pleased with the FIT50's quiet, soothing sound levels -- allowing us to sleep during the disturbing smoke episodes. It undoubtedly reduced the smoke levels in the master bedroom.
Delivery was amazing quick (after the units became available due to high demand. Submitting our email addresses to the wait list actually worked, thanks!)
We live in the San Francisco bay area. When it is "fire season" the air can get really bad. We now have 3 of these FIT50 air purifiers and they keep our air clean. I love the way the unit tells you how the air is improving with the change of the light color. I have recommended this unit to several friends and they really like this unit as well.
