They are worth the money. Once a week I just clean the filter. No more having to go run out to the store to buy replacement filters.

My air return is in the hallway ceiling. It is hard to tell just by looking up at the air return if the filter needs cleaned without taking it out. My filter arrived slightly damaged, but still useable.
