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!

I only buy Filtrete, they're the best. Unfortunately my 10 year old furnace died 2 days after I received these filters and I never had a chance to use them. Replacement furnace uses a different size and the company I used provides free filters for 2 years so I will be returning these. Will buy the new size from Sam's when the free filters run out or if I decide the free filters aren't doing the job.

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.

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!

The Filtrete Ultra Allergen Bacteria and Virus filter seems to be helping reduce my allergies, especially when used in combination with room air purifiers. The MERV rating of 12 is higher than I usually prefer since it can restrict airflow, but these filters make it worth having my A/C work harder throughout the day. They offer great value when purchased in a pack of four, and Filtrete is a leading brand in air filters.

The filters themselves are good. The delivery, not so good…..one corner of shipping box was smashed and wet when received. Filters inside had corner damage and were wet. I live far enough away from Sam’s that I decided to use instead of trying to exchange…. Dried them out so should work okay.

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 :-)

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.

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
