MERV 13 Filtration - Now available in 1-2-4 and 5" Filters

I receive many questions regarding Pleated filters and what is the "Best" filter available today.  Now since many of our customers utilize 1", 2' and 4" filters, I will address only standard size filters.

The American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) designed a scale to rate the effectiveness of air filtration back in 1987.  This scale is known as the MERV (Minimum Efficiency Reporting Value).  The higher the number - the better the filtration

There is a balance between cost of replaceable filters - suggested length of service - and filtration.
Recently MERV 13 filtration has been designed and released into  1", 2" and 4" pleated filters.

Below is a pictorial of how a MERV 13 filter is designed.



Glasfloss - a major manufacturer of Air Filtration released the MERV 13 pleated filter optimized for "LEED" compliance in new and existing building as well as providing a cost effective upgrade to the popular MERV 11 filter.
