Perfect fit! Not everyone carries the 20x30. Great price for 4.

Glad to see them, not on list buy on last filter.

Beat quality filters and great for the price

Great product at a very consumer price!

Good Quality Filters - Excellent Value

Great buy! Fraction of the price from other stores and keeps my air clean

I ordered these to help my wife and son who has allergies. Works great!

Works great Change every month

Great product- well worth the extra dollars for cleaner air. It works!

I like being able to buy in bulk.
