[This review was collected as part of a promotion.] I only use 3M filters for my home. Grabs all the allergens out of the air and traps them in the filter. Would like to see the price drop though.

[This review was collected as part of a promotion.] We live in an old house, and even though the heat/air system is not old, we rely on good filters to help control dust and allergens. The Filtrete Allergen Defense Air Filter does an excellent job.

Be advised all the one star reviews are correct for these products. They made them 1/8" too big for the air filter holder. Shame because it is a good product otherwise. I smashed my 20x30 into the hole and will use it anyway. LOL

I upgraded from a different filter when I was diagnosed with asthma. What a difference! The old filter never caught nearly as much as this one. That makes me cringe to think of all the stuff being blown back in to the house. :-(

[This review was collected as part of a promotion.] Just started using the filter in my new house after living in an apartment for many years and always being given the cheapest filters on the market

I have been faithfully purchasing this 2X Dust 3M Filtrete, because of its quality MERV 11, and double filtering capacity! The best you can buy and a good return for your investment!

[This review was collected as part of a promotion.] The Allergen Defense Filter works well in our household, because of allergies and cats. Much better for us than other filters.

[This review was collected as part of a promotion.] for the price i paid i think this is a good buy. i highly recommend and specially with a husband with allergy through out the year this helps to prevent it

As I always change my furnace filters every three months and document it. I find that Filtrete makes a competent product. You can always tell if the filter is working by how dirty the folds are. This works.

Online order for card cash back. In store pickup while doing other shopping. This is a quality filter that outperforms the old fiberglass. With the quantity package and discount, this is a value.
