Filtrete FBA22-3PK Basic Pleated Air Filter, 30 in L x 20 in W x 1 in T per 2 PK3

I have been buying these filters for 10 years and have loved the quality, what they catch and the cost for a 3 pack. I always get two packs to have 3 changes. I change them between 2 to 3 months apart regularly. However; since the change that was made in their actual "1" inch width NOT so satisfied with the 3 Pack anymore. They are so thin they whistle ALL the time and it is so annoying when trying to sleep. I haven't given up on Filtrete yet, I returned the unopen packs I had and purchased a 2 pack 1085 Micro Allergen Extra with a true "1" inch edge/rim. I sure hope they are quiet like the other filters used to be when they were thicker. Unfortunately they are twice as expensive. Love to see you change the thickness back and even you had to raise the cost just a little.

The Basic air filter is poorly designed, having the wire support on the intake side of the filter material. It used to be on the back side, and whoever made this change must have made a mistake. A strong airflow can pull the filter material off the support wires, and into the blower, if the filter is installed per the arrows on the frame of the filter. I'll turn my filters over, so the support wires are on the outgoing side. Next time, I won't buy 3M filters.
