As one who has basically tested as allergic to the planet, I find these filters do make a difference. Well made and get the job done.

This price is great for 4 of this fillters. Typically pay $20 a piece at other big box store. Thank You Sams

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 have used this type filter for years and they have done very well in keeping my furnace and air conditioning free of dust.

I got the filters without any issue. I've installed one and will know in a few months how well they work.

I was sneezing all the time from cheap filters. I switched to these and everything cleared up within hours.

Online ordering and delivery of the air filters in bulk is convenient for having them on hand when it’s time to change them often.

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

These filters have worked very well for us. When I change them you can visually see the trapped dirt.

I have not use but I have order before and use the brand but this time the price was higher and no rebate or discount,
