These catch a ton of airborne particles that can collect on the fan blower, evaporator coils or the furniture.

We've used these filters for decades. They are the best for allergens. Sam's prices are the best we've found.

This is the only brand of filters we buy. We live in the country, so lots of dust. . .these work great to help keep the amount of "yuck" in our air!

This is a very good filter. I have allergies and these filters cut way down on the dust and various seasonal irritants.

We have been using this product for several years and have been told using them has been good for our new heat and air system.

My home air quality definitely improved. Although they are bit expensive but I’m glad I purchased these filters.

Check the "Merv" recommended for your make and model of furnace. This matters for the efficiency and longevity of your furnace.

I have used these for several years and for some reason this batch isn’t keeping the dust down like before.

Filters are exactly as ordered. I love this brand; works really well. Tomatoes are just right as far as ripe, color, flavor.

Good filters, not as good as the higher rated, but worth the money when Instant Savings discount in effect. Hence the rating.
