Mechanical Efficiency Holds Its Charge Throughout The Life Of The Filter


The BestAir PRO MERV 11 Whole House Media Elements are designed to replace existing media elements used in SpaceGuard® AprilAire® And Lennox® Brand Residential Whole House Media Air Cleaners.

When installing the spacers into the media element, the media pack must have even pleat separation for proper finger insertion.  This is essential to not only make installation easier, but to also prevent tears and pinholes in the media from forcing the fingers into an uneven area.  

To create even separation, OEM filters drill holes in the media and insert a rope or string to assist in expanding the media pack.  Air flow operates on the same principles as water and takes the least path of resistance.  Holes in the media pack instantly create breach points for unfiltered air to pass through the filter.   

To improve on this design, the BestAir PRO MERV 11 Whole House Media Elements use a glue bead separator located on the outer perimeter of each pleat.

In addition to the improved design, the filtration efficiency has also been improved.  The MERV 11 media element is the first ASHRAE 52.2 rated MERV filter to remove more than 65% of particles  from 1 to 3 microns in size.

Filtration medias installed for prolonged periods of time have been shown to have a lower filtration efficiency over time if a static electric charge has been applied to the media.  The BestAir PRO MERV 11 media elements use mechanical filtration to maintain their efficiency throughout the life of the filter.
