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.

Excellent filtration and price. I have confidence in the manufacturer and so happy that Sam's carries these products.

Great brand and great product. Cheaper to get my filters like this than have to pay half that price to get one

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.

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.

These seem to work very well, there is much dust around the house since we’ve been using these filters

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

I use them all the time-good buy for the price.I wish they were available in all Sam's Club stores (size)

Best Effort with Animals but requires changing monthly or I find dust starting to get inside duct intake

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
