We've used these 1600MPR type filters from Filtrete for several years in our 1400 sq foot, 2-story condo. It does a good job for its intended purpose as near as I can tell. Although I'm not able to see allergen, bacteria and viruses, I do always see a discoloration on the pleats when I change-out the filter at 3-month intervals.

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.

I own an older home. My HVAC air return is an odd size. Can never find it at other retailers. Its always in stock online and at a better price with Sam's. I place my order and 2 or 3 days later the box is delivered to my front door! No shipping charges since I'm a plus member!

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 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.

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

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.

This is a quality high air flow filter. I took static pressure measurements with and without these filters and adjusted my HVAC max air flow settings for each zone to stay within a 0.5 to 0.8 range for static pressure. I installed 3 of these filters and 4 months later they are still clean and having almost no impact on air flow. These filters are far better and flow significantly more air than really cheap 3M filters. They also fit the housing tighter and seal better. I know because I had some from previous owners to compare. I gave that junk away on marketplace. These combined with a robot vacuum and mop have kept my home virtually dust free over these 4 months and they have a lot of life left. If you think these restrict your air flow too much, you need to get your HVAC settings adjusted and possibly get professional help if your ducts aren't sized properly. Air flow issues are a problem with your system, not with these high flow filters.

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!

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
