| Merv 11
pleated filters are made with electrostatically charged synthetic media and are MERV
11 rated according to ASHRAE 52.2 standards using 24 point beverage board
while our 4" deep filters are made with 28 point beverage board.
The pleated media is bonded to expanded metal which is coated with a
rust inhibitor. The entire inner surface of the frame is coated
with adhesive to encapsulate the pleated media pack and prevent air
bypass and provide rigidity.
