Air Filters

One of the major problems with average filters is that they collect mold spores and bacteria at a place in the air conditioning systems where moist air passes through.


This dangerous formula helps support microbiological growth. You have all the elements of moisture, micro-organisms and organic food harbored in one spot. When the filter is not adequately protected with an antimicrobial, the possibility of that filter becoming a nest for microbial growth is heightened.

Read below to learn why 4 Corners Home Inspections highly recommends the PerfectFit Filters for your home.  

MERV 7 ASHRAE rated standard

PerfectFit Filters are rated MERV 7 for performance and meet the rigorous testing standards set by ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers). A MERV 7 filter is the best filter to avoid blower motor burnout while still filtering out particles better than an expensive HEPA filter, providing an acceptable level of efficiency in collecting average size particles to reduce dust.


Internal frame eliminates paper cardboard

Most one inch filters, (even the most expensive pleated filters), use a cardboard frame to support the filter. This cardboard is organic and can become a source for mold and bacteria. Once mold and bacteria grow on this frame, the toxins produced enter the air stream and significantly reduce the quality of the indoor air you breathe. By utilizing an internal frame and no cardboard, there is nowhere for mold or bacteria to grow.


Edge-to-edge design for PerfectFit

Because the frame is internal and the filter surrounds the outer edge, the PerfectFit Filter fits the opening perfectly! In cases where the return grill might be oversized, requiring two filters to be placed side-by-side, the PerfectFit Filters overlay each other to seal the two filters without using duct tape or some other adhesive.


Quieter than average filters

Because the PerfectFit Filter is a double layer of filter material that is thicker than a pleated filter, the PerfectFit Filter serves to quiet the noise often associated with the air handler or blower motor. Customers have commented on how quiet their system seems after having installed a PerfectFit Filter.
