AirThredsTM makes breathing clean air as easy as doing your laundry.

Installed this at my GrandParent’s house so I don’t need to keep buying the non-washable ones. Easy to install and is working perfectly so far. Stay green!

Worked great! The first time I changed it was last week and it really collected a ton of dust and seems to cleaned right up!

I always had a problem inserting the filters into my A/C. They seemed to be a touch too wide for a 20×20 and got hung up. I destroyed many a filter that way. This was easy to assemble and just slid right in.
