FILTRATION GROUP IAQ 10441 FILTER AIR MERV 10-PLEATED 14X20X1IN

The Aerostar Pleated Air Filter - Series 400 incorporates a 100% electrostatically charged synthetic media with an ASHRAE 52.2 average atmospheric efficiency of 25% to 30% and an average arrestance exceeding 90% by weight. The 1 and 2 inch filters handle velocities up to 500 fpm - the 4 inch filters up to 625 fpm. The media is bonded to a metal grid on the air-exiting side, preventing fluttering and maintaining uniformity of the pleats. The filter pack is enclosed in a heavy-duty, moisture resistant, die-cut frame that will not warp, crack or distort under normal operating conditions. Front and back media retainers are an integral part of the filter frame. The media pack is bonded to every part of the frame, preventing any possibility of air by-pass.
