I have been buying 3m filters for my ac from SAMS club for years but the last batch has issues. I think it is too restrictive and causes my furnace to cut off or short cycle. A new filters fixes the issue but returns in less than 30 days, I can feel the decreased airflow in the registers. Also, I recall the 3M filters used to have rounded folds in the filter material however these newer ones have very sharp folds like a W or V. I am not sure if the earlier version had a lower merv rating. I can no loger use these for more than 20 days, and we do not have any pets or a dusty house.

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.

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’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!

I believe they work. Have the 1st of the pack we purchased in my handler now. I can't speak for the way they are supposed to remove odors, mold, dander, etc..as they say they do, but I need to replace my filters once every month as required by my property management company so I got these. With the price we paid its about $10 a month. I am good with that!

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.

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!

Rating is not based on scientific analysis but based on observation and long-term use. The 1600 MPR appears to substantially reduce as claimed pollen, pet dander, smoke, bacteria and viruses. The latter two elements cannot really be determined. Changed every 2-3 months and the amount of collected debris in the filter is supported of filtering.

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 appreciate the price Sam’s club provides us for this air filter. It’s almost half priced as compared with the other retailer. The 3M quality is always the best. I can immediately feel fresher air in my home after replacing the old filter with this one. I bought 12 packs with this price, enough for next 3 years. I highly recommend this product to everyone.
