These have always worked well for me. Price is okay

So far superior to cheaper brands

Just what I needed at a reduced price!

Good filters. Only 4 stars since of the filters had a manufacturing flaw that rendered it unusable.

high filtration rate. Love it for my allergies

These filters work great. we change every 3 months

Great brand, great filter, great price.

Great product for keeping air clean. These furnace filters are our top choice.

These are some of the best AC Filters. But why do they cost so much.

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