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.
