Works as expected. Usually change it after about 2.5 months. My air conditioner registers are much cleaner since I've started using these. There's no more dust build up over time like with cheaper filters. Well worth the price for cleaner air.

Thin fiber filter came ripped with an egg sized hole on 1 filter of my most recent purchase. Not packed with care. The size is what I need so it is what it is.

These work great. I’m so glad Sam’s carries this size. These usually last 3 months between filter changes. In the summer when my system runs a bit more I’ll change the filters every 1-2 months.

Great discounted price! And Sam’s Club surprised me with a free package of delicious danishes, when they immediately brought to car. Told they do this sometimes, how nice!!

I always bought the inexpensive filters which needs changed each month. Then i decided to try the Filtrete filter. So much better i got this pkg on sale. I will always get these, they only need changed every 3 mos.

I was finally able to buy the correct size filter for our furnace! We've always had to buy a larger length and leave some hanging out of the furnace because most stores don't carry the size our furnace requires.

I always wait until these are on sale and then I buy what the limit is to try to stock up for a year. With prices going up daily, I'm glad to see a sale. Sometimes it's difficult to find the right size in stock.

Quality filters at a much better price anywhere else. Bought the max limit of 4 sets of 4, and were delivered in 3 or 4 days. Great value and hope the special runs again in a few months so I can get more.

Great quality for the price. I have used others very strong filters as I have cats. They were supposed to last 90 days but did NOT. These filters appear to be staying clean.

I been using these filters for a long time. Change them every 60 days. Highly recommend them. When I have my furnace inspected every season, they tell me it looks great.
