This! Impressive—shortly after replacing the filter, I sensed the cleaning of air in my bedroom as well as downstairs (my home is 1600 sq ft). Fast acting!

I thought I was buying the white filter replacement but a black one came. I didn’t want to send it back and wait for the correct one as it fit in the unit. I suspect the warehouse made the mistake.

Works well. I really like the air purifier, makes a big difference in my place. Update 7/4/2020: The original unit is not clearing the air as when I first purchased the complete unit. I don't know if the filter is faulty or if the unit itself is not working to full capacity. I do keep it running 24/7 since I have two cats, plants and allergies. It is not noticing foul smells and cleaning the air like it used to. I hope I don't have to replace the unit so soon, just purchased in 2018.

I’m happy that I’m able to get the filters from Wayfair too and I don’t need to be looking every where for them. Thanks Wayfair

The replacement filter was a reasonable price along with free shipping.
