I've used these filters before, and they seem to work great. I've not noticed and issues with the HVAC system. Sams Club are much less expensive than most other retailers for the same filter.

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!!

These are great filters. They are thicker and sturdier that other ones. We change our monthly and they capture the dirt and odors. Cost is the best compared to home stores.

These filters arrived quickly and neatly packed. The value for the 1600 style filter is very good considering I have paid more for a lesser quality filter from another online retailer. I’ll order these again.

I purchased the Filtrete 90 day filters while an instant value and received a one year supply for $6 off the regular price. I trust these filters to keep my furnace and A/C operating at good performance.

I am always cautious about buying filters by mail because the carriers often destroy them if they are not packed carefully. My filters arrived in perfect condition and I install them immediately without any problems.

The filters are good and was cost effective when I was shopping around! I gave it a 4 star because there was a bug on one of them when I opened it! But other than that, what I needed it and good deal for the price!

The best when it comes to necessary for the home. Living in Florida where we have lots of allergens, and especially during dry seasons, we all want the best filter available for our homes.

Best filters I have found for our home. Very pleased with them. You should change your filters every 30 days, however, I have gone 6 weeks with these and still had good filtration and flow.

4 pack that is in stock at the Sam's Warehouse. When on sale, I purchase them, and with no expiration date, change the filter at my home once a month.
