I've been using these for years. I buy them when they go on sale, so I'm always stocked up. The keep my heating and cooling system in great shape!

I absolutely love these filters. They keep my furniture clean!! If the furniture is clean it is the reason we are not sickly!!! The air is clean !!

Quality product that I have used before and will continue to buy, product does a real good job filtering out household contaminants.

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

My son an HVAC technician said too high of a rating makes your furnace work harder. This was the only filter I could find that fit my furnace

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

I like the Filtrete filters but they’re expensive. Sam’s has the best price. Will order my filters from Sam’s from now on.

Great filters. Every chance I get I purchase these filters. They really help keep the air free of animal hair and other types of dust.

I have read filtrete is the best, I know that they're the most expensive but I have been using them for years, wish they cost less.

Since using these filters, my allergies have been much better. I like getting 4 at a time instead of one or two because I have several registers.
