This is a really great deal for filters that need to be changed every 30 days. It gets so expensive when you have to buy them one at a time so I was really happy to find a four pack! They have all sorts of sizes and honestly, you can buy three of them and get by for a whole year!

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 :-)

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 always buy 3M filters. They feel like they work the best and are well worth the extra money than the plain-jane filters. Not only do we live on a gravel road in the country, we have 2 dogs that are inside/outside and shed. I also have some allergies, These filters help tremendously!

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!

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!

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!

Excellent filters at a really good price! These really eliminate the finer dust and pollen particles in the air in our house in SC. We have noticed a drop in accumulated dust on horizontal surfaces in the house since we switched to these very efficient filters about 8 months ago.

These filters work very well & keep my house & vents very clean! No allergies either & priced a bit high but lower than at other places. I date them & change every 3 months. Once I vacuum cleaned them to reuse once and they held very well for over 6 months!

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.
