Due to COVID we are having trouble getting filters from our suppliers as there is a national filter shortage. There will be a delay in getting the filters to you, and we do not know at this time when we will be able to ship them. Please call the office at 303-423-1982 for more information.
This filtration system is the most highly recommended and most often used system. It effectively captures 40% of particles at 1.0 micron and larger, which is 11-times the efficiency of standard pleated filters. This filter also resists moisture found in air conditioning systems, and does not support microbial growth on the pleats.
(For 14"x14"x4" return air filter grilles ONLY - NOT for Media Air Cleaners. Can ONLY be used on 14"x14"x4" filter grilles.)
(All pricing INCLUDES taxes and UPS Standard Ground shipping.)
(We recommend a 4" filter change at least 2 times per year - September & March. For DIRTY environments or most efficient filtration, you may need to change filters more often...do monthly visual checks for the first few months.)
