Austin Air - Pet Machine

You don't buy a purifier for removing hair, that's not the function. And your purifier is not for pet odors as its for any odor. 1. Be honest on the square footage. If you leave the door of the bedroom open you just turned the right sized purifier into the wrong sized purifier. Either the door is always closed and you need a 150 sq ft unit or you need one for the bedroom + the hallway + the other 2 bedrooms, so you really want a whole house 2000 sq ft model. Same logic applies to the living space as unless its closed off, you want one for the entire area. 2. If item 1 is frustrating, you can alleviate this by just buy two 1000 sq ft units for your 2000 sq ft house and spread them equidistant. Or one 2000 sq ft unit. 3. The big BIFL brand is Ausin Air as it has a 5 year warranty, 5 year filter and also comes with carbon filter for smells. Find the unit(s) to cover your area's size.

Austin Air - it’s a tank and made in USA. No fancy controls . Heavy metal frame big fan. Filters last 5 years. Some of their filters can filter chemicals.

I ended up getting an expensive Austin air purifier appropriate for medical use because all the cheaper brands i looked at intentionally or accidentally produce ozone, which is not healthy to breathe.
