Wow, this filter works great. I get mysterious in the house, live with other people I don't know! I didn't want to sacrifice quality and I'm glad I chose this brand! Costs money! I hooked it up directly to a 4" Terrabloom variable speed auxiliary fan. It pulls air through a filter in a sealed enclosure. It operates almost silently and does a great job, contrary to what people have told me, a great one, powerful noisy vortex fan it has been working for 2 months nothing blows outside the closet bought the gel just in case but never had to use it.
