Something to think about. Take a home that is 2000 square feet. Multiply that by a standard eight-foot tall ceiling. This yields 16,000 cubic feet. If we use a fan rated at 50 cubic feet of air flow per minute (CFM), times 1440 minutes in a day, we have 72,000 cubic feet – 4.5 times the volume of the home – that is being blown out the window each and every day. Annually, that's 1,642.5 housefuls of air that you paid big bucks to heat or cool. An air purifier such as the Purrified Air litter box air purifier costs about $4 per year to operate in always on mode. Filter media replacements are about $80 per year. That is way less than the cost of 1,642.5 housefuls of heated or cooled air.
