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

Filtretes seem to do a very good job and are well made. 20x20x1 and 16x20x1 are accurate measurements. The larger filter for the downstairs system needs to be precise to slip in. Other cheaper brands have been a teeny bit too wide and an ordeal to install. 5 Stars except 3 for Presentation because when this set arrived one of the ends was a bit smashed. I will straighten them out to work.

These filters are well worth the extra cost over lesser filters. They really work as advertised and they are sturdy enough to last for 2 to 3 months. I went from MERV 9 filters and was very happy with the results.

Love these and how convenient they are instead of going to the store to purchase.

A bit pricey

filter was advertised as filtering smoke but it did not do so with our forest fires in Sept here in western Mt.

Ive used Filtretes furnace-A/C filters for many years. My wife and friends doesnt sneeze at all or as much with these compared to other filters.

I have allergies and asthma. I can tell they work because in the summer months I am fine until I go outside. Then my eyes water and nose runs something awful. And I get allergy shots and take allergy medications.

I use only this brand for allergen concerns. The Heavy Duty Filtret Air Filters are good, expensive, but many times I dont need to change it monthly as recommended, unless I have been running my central a/c or heater non-stop.

Better than the cheap stuff. Hopefully they last longer than the other ones.

I did not buy these filters from Amazon. Well, actually I did. I ordered 20x25 and received 14x25. So I went to Lowes and bought what i needed. Amazon would not refund my $$ because I did not note the mistake until after 30days. These are great filters. Very efficient, long lasting and bluetooth enabled. The Filtrete app gives you updates on the status of the filter & lets you know when it needs to be changed.
