These filters catch the dust and pollen that others let through. I am very pleased with these filters, they are not as inexpensive as the others but do a better job., NO MORE SNEEZING.

I have to buy filters and replace once every couple of months due to my dogs and this is the cheapest place to find them. They are almost $20 any where else.

Been using these for 3.5 years now and they are doing a great job plus when you buy them at Sam's on sale, that even a better thing cause it's a great deal!!

Hi quality filter that works great. We change the filters every three months, seems about right here in the desert southwest. Great price at Sam's for a 4-pack, and usually in stock when we need to restock.

Great to see these in side the Sam's Club store considering that are a very pricey piece of equipment wherever you go. Therefore seeing then in bulk only helps the customers.

Very inconsistent in size. The actual dimensions are bigger for a filter in the pack, while a different filter has correct size to fit the vent opening. Very frustrating!!

I love these filters. I can feel very confident knowing that all pollutants and contaminants are being filtered out. The added bonus I wasn't expecting was having less dust in my home.

Great Filters to use, our service guy said we could go up to 3 months before changing them out with good filters. We change them every 4 - 6 weeks but knowing we could go longer using a good filter is good to know.

Love these filters!! I have been using them for a number of years now and have figured out that changing them out every two months works best for me. I try never to run out of them even if I have to buy a single filter elsewhere occasionally.

Always bought these AC filters at Sam's when on sale. Good value and it works. Online site shows all the sizes. Free delivery via UPS or FedEx for Plus members. Recommended.
