Filtrete 16x20x1 Air Filter, MPR 1500, MERV 12, Healthy Living Ultra-Allergen 3-Month Pleated 1-Inch Air Filters, 6 Filters

Received incorrect size originally. Amazon made good immediately. Correct size identical to what I buy locally, but much less expensive. The 2-pack came in 3M shipping box. Installed easily. The box arrived with a damaged end, but did not damage product such that it couldn’t be used properly or effectively. That wasn’t sellers fault.

These are pretty amazing. They don’t last too long, but that makes sense, they’re supposed to pull allergens and dirt from the air to filter it. So, with a good filter, they shouldn’t last long. With two dogs, I feel so much more confident with these filters!

When I was ordering, I needed 20X25X1 ---that is what I had searched for and that is what I clicked on. Since I needed 4 of them, I selected a 4 pack. What I didnt realize was that when I clicked on 4 pack, the size changed and when I received the order, I got 20X30 X1. Of course I had to return those since they were too big-----and then I was charged for shipping, so there wasnt enough money to order the correct size. I ended up going to a local store and finding something that would work. I tried the order again (not ordering, just seeing if that would happen again) and when I clicked on a 4 pack or other bundle, sure enough, the size changed. So, just beware that could happen and check and check again to make sure you are ordering the right thing.

These work great.

This filter removes a lot. This is how mine looks after just one month, so I recommend replacing them that often.

Filtrate filters are thicker to block more allergens. However, my apt has an older model a/c unit. The system couldnt pump through the thicker filter. This caused my a/c unit to freeze up requiring emergency maintenance. So know age of your unit before you order and install these filters.

I live in a year-round allergy state where basic filters just dont do the job - have always used Filtrete but switched to MPR 1500 Healthy Living Ultra Allergen to combat allergies even in the winter. We live in a moderately wooded area of suburbia and took the advice NOT to go with the thickest Filtrete filter available, which would require replacing monthly instead. The Healthy Living Ultra Allergen filter seems to be the happy medium; only required replacing after 3 months during the winter and the same into the spring months - so far, noticeably better than the basic version. About to enter the summer months, expecting it to work just as well.

Fits perfectly and appears to filter well. Good price too.

Ive been buying the Filtrete MPR 1500 Ultra Allergen filters for years. I will likely never go to another type of Filtrete, not to mention a different brand. If anything, I may go up a level or two if I ever anticipate lengthy construction projects in my home. However, I can say without a doubt that I feel my 3200 sq ft home has noticeably cleaner air. Ive even had a slip of the mind and didnt change the filters for over four months before. Keep in mind, thats NOT a good idea. Nonetheless, the filters kept working fine and I noticed no degradation to my HVAC and during regular maintenance, there were no issues in my home system. Again, I strongly advise replacing them every three-ish months or less. Id say that during normal operation, one should inspect the filters at least once a month. These filters are not restrictive whatsoever. I havent noticed any issues in my heating and cooling for as long as Ive used them--including when I accidentally went over in their lifespan. Ill keep buying these for as long as they make them and quality is maintained! Unlike some other reviewers, I have never had an issue with quality. Id also like to point out that I do not care if the cardboard around the filters has tiny imperfections. Its hidden and has never affected the air quality or function of my system whatsoever. Buy these! You wont regret it.

Love these filters. Helps allergies by doing a better job of filtration.
