Honestly I didn't want to go as high as MERV 12 for my 2-ton SEER 14 HVAC system, but the brand I was purchasing MERV 10 filters from lowered the quality of their products. 3M makes good products and as long as my system doesn't work too hard to push air through filters this high rated then I believe it'll be fine.

It is absolutely outrageous how these large companies continue to take advantage of the hardworking people by pricing items like this so ridiculously high. There is no reason for the huge price increase in this product! The quality hasn't increased. The amount of time they last hasn't increased. Nor has the amount that this company pays their employees increased. And yet the price that they charge has gone up dramatically.

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.

They fit the opening OK and seem to work fine. I can't tell by using them if they do or do not capture allergens, bacteria and viruses.

Look! I had my attic coil cleaned, the guy went up and came back down!! I said “ boy you are quick “ he said my coil was as clean as he has seen. All due to changing my filter with Filtrete filters!!!

Excellent filter at a great price! It fit perfectly, seems very well made, and gives me confidence in the air quality in my home. Definitely a great deal.

Best price I've found for these ultra filters. Colds and flu are much decreased since starting to use these filters. Dust is minimal (for Nebraska). Would recommend it someone in your family has pets or allergies.

These have been great for my sinuses! They are all we use now. There has been a drastic reduction of dust on our hardwood floors.

Did not fit properly was off by a few mm it’s the same size as the one currently in the vent however not sure if it was not cut properly when manufactured but had to squish it in place

So happy to see Sam's carrying this 16x 25 size usually I have to go to a home store to purchase not to mention at 2x the price. I prefer changing them often because of all the dust in Arizona making my home fresher, healthier. Thank you
