These are the best filters we found at any store, including the local hardware stores. We wait for them to go on sale, and usually buy two packs, as we change our filter every month. Thus far, we feel that these filters are helping to keep our furnace cleaner and our air clean. Definitely recommend.

These are good filters. They are good quality and stronger than the cardboard filters. These have a wire mesh on both sides and stay firm and strong with the air flowing through them. They hold a lot of dust and keep the AC unit very clean. Keeps a lot of dust from flowing into the house. Keeps the air cleaner.

I bought these "higher end" filters from Sam's Club (online) for a great price, and had them shipped directly to my home. I already knew the quality was good but I was shocked when the filters arrived with no damage whatsoever. No dents, no dings, no moisture . . . perfect. They were in better condition than what they would have been if I had bought them from a store in person.

Filtrete is a very good filter. Traps the pollen this time of year. I have a dual heat pump that has different Returns and the settings. One upstairs and one downstairs in the ceiling. I also have a larger return in the Den. All work well with Filtrete filters. Rarely have to dust!

I know HVAC workers will cringe when I say this, but we really like these better than the cheap ones they HVAC workers say to use. I don't think they're a waste of money. Having the pets we have, being smokers, and living in an older house that's hard to keep dust and dirt out these help much better than the cheap ones. Instead of changing the cheap ones 1 or 2 times a week, we can sometimes go almost a month with these

Seems to have only a few less pleats as a 1900 limited info out there on these but I'm glad to have a budget option that seems to perform well and let's the HVAC unit breather easier. More pleats equal better air flow and less static pressure for your system when it starts to get dirty. Less stress on HVAC units

I have used these filters for several years and don't have to change them out as often as other brands. Although it states they last 3 mos, I usually swtich them around 2 mos in summer. I don't have much along allergys so I can't speak to it's effectiveness or maybe that's why I don't have allergys :-)

We had a difficult time locating the Ultra Allergen 2X Bacteria and Virus Filters in the correct size (18x20) for our furnace, but finally found them online from Sam's Club. We are grateful for the ultra-allergen / 2X bacteria and viral protections provided by the 3M Filtrete Filters. We also appreciate being able to shop online at Sam's Club even though we are not members. Wow!

I’ve been purchasing my furnace filters from Sam’s for a few years now and it appears these filters are much sturdier than those I have purchased in the past. Great upgrade in product and as always, great customer service/support. Thanks, Sam’s Club!

They were received in good condition from the shipping company. We use these filter because I have a severe respiratory condition, These filters help keep down microscopic particles that could exacerbate my condition. In my option they are excellent filters.
