I have been in the business of Indoor Air Quality for many years now. This filter is incredible. It actually replaced my 1 inch filter and I know it will last a whole year in my home. This filter is 5 inches deep and fit into my one inch housing. There is no substitute for depth for energy savings.It works like the ducted home air cleaners for a lot less. Amazing filter. I can only immagine what the odor control can do.Try this for yourself.
