That air cleaner looks nice. We're looking to figure out a way to do a whole house air cleaner when we remodel. We're thinking of installing a small-duct air conditioning system. It doesn't blow dust around like the old one that used the hot air ductwork. We've gotten to where we run the a/c's earlier in the spring and long into the fall simply for dehumidification, and we don't want to open the doors during allergy season, which happens in the Spring AND Fall around here.
This one does the whole house. I don't understand exactly how it works. But I know it will do up to at least 3,000 sq. ft. (no, we don't have that much room).
'Course the cat's kinda got this nice orange glow about her these days...
