We have been using these in our home for years. We change them about 2-3 times a year and appreciate this value at SAM's.

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.

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

Have not opened these yet but it is a product I use almost exclusively and is always a good performer.

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

These are great! We found out that my son is allergic to our cat. These filters help a lot! And I have noticed we have less dust.

My daughter has allergies and these filters work great and really seem to help with the desert pollen

These filters were supposed to fit but they were too long. I purchased same at Walmart and they fit.

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.

Great filters, finally in my required size for in store purchase (14x20x1). Was only available online ordering before.
