This is the only filter I’ve used since taking over the job of replacing the filter in my home, no problems with doing it at all.

Excellent filters, I have 2 dogs and bad allergies, these filters make all the difference in how well I breath.

I love these 4 packs! They are the most affordable way to purchase air filters. We love them because it helps keep our air quality up with 3 dogs.

These filters do a great job of capturing all the harmful particles that can cause problems for my wife's COPD. Highly recommend this product.

I change my furnace filters every time the season changes. This makes it handy to order a year's worth every spring.

Great Buy! I have used this product in the past and I know I will get the experience every time I buy this filter.

These are pretty nice air filters. With all the pollution in the world it's nice to be able to filter some out.

I am very happy with this item and price. If you keep this in stock, I won't return to Amazon for it.

We purchase these quality filters (2-sizes) every 12 months at a great price compared to other stores!

Four pack of 12 x 12 air filters cost $20 ea at Home Improvement stores. So four pack for $39.99 is a deal.
