I have used Filtrete filters for years and they are consistently effective in pulling pollutants out of my home leaving it much more fresh. With droughts and dust a real problem this year the allergy causing agents are plentiful and everyone needs to use the higher grade filters for easier breathing!

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.

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.

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

My friend recommended these filters and I'm very happy using them. The air is a lot cleaner; I don't have to change the filter out for 3 months. I highly recommend, although pricey, it is definitely worth the money. Also, they have a reminder when to change out filters.

When I saw these on sale at Sam's, I immediately went down to stock up. They clean the most miniscule particles of dust, debris, and other particles from you recycled air, and add years of life to you HVAC unit by preventing this particulate from getting caught up in your coils.

I have tried cheaper brands but I always come back to filtrete. They have different merv ratings for different situations. I have Saint Bernards and lots of dog hair and dander and it takes care of it all.yes they are expensive but worth every penny.

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!

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.
