According to the Air and Heat techs this is the perfect filter to use monthly. I am happy with the price of the filters and they keep my utility bill lower.

Just what’s needed for returns to protect the equipment and not plug up from too much filtration and starve the blower fan.

Because these need to be changed more often, they are not as good a value. Unfortunately, my furnace can’t use the better filters.

I found that the High Merv filters for Allergies are too resistant. The air flow is restricted. When the AC is trying to keep it cool at 115f + it needs a full , unrestricted Flow for efficiency.These are perfect for me. The sides are hard , as not to collapse under high air flow and filter just great.
