Excellent filters. Been using these for 10 years. We change every 3 months. Sam’s has the best price especially when on sale. Fast shipping. ❤️

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.

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 liked and used Filtrete filters for many years. This is a great price for a product I usually buy.

These filters are very good. They are also very very expensive but the convenience of getting them while I'm out is why I buy them.

Its just 25 days I used this product. My wife felt a change in dust layers on furniture n felt air more fresh n not muddy smell.

I’ve used different brands and 3m filtrete is the best I’ve tried without the ones paying an expensive price.

This is such a great deal buying them in a 4-pack like this. They work better than the cheaper ones I was buying before.

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

Great value pack of filters that do a super job in your furnace filtering out dust and allergens. Highly recommend Filtrete brand air filters.
