Reduces the need for cleaning

The fact that the air in your home is cleaned on a continuous basis reduces the amount of dust and other particles on all surfaces. Thus your home stays fresher for a longer period of time and the need for dusting and vacuuming diminishes.

Air tight furnace filter
 




We eliminated the path of least resistance.

To insure that all the air and pollutants go through your furnace filter and  not around it, your new filters feature our patented anti-bypass seal.  When your air conditioner or furnace turns on, the difference in pressure causes an air tight seal.   No bypass means your filtering 100 % of the air.




Air Filtration Options:

You'll choose from two types of air filtration refills for your new furnace filter.  You can use our popular BioSponge plus®, or our ultra-efficient MicroSponge® refills in your new filter. 

Both offer outstanding protection from airborne contaminants!  Select the refills that fits your needs.  You can also choose to add an activated carbon refill, if you wish to control odors and V.O.C.'s.
