Filtrete 12x12x1 Air Filter, MPR 1500, MERV 12, Healthy Living Ultra-Allergen 3-Month Pleated 1-Inch Air Filters, 4 Filters

I can’t find my downstairs size filters in any store. This is my favorite that I’ve tried so far.

Often now, dimensions are a bit off… to save material, many companies manufacture on the small side. These fit perfectly, preventing unwanted flow around rather than through the filter. I used to smell cigarette smoke from the basement, but that is gone with these filters. Our daughter’s allergies have improved, there is less dust building up on furniture and yet airflow is not reduced even as the filters age. A little pricey, but worth it if you have these types of issues

3M produces the best air filters in my opinion. I’ll keep buying.

They seem to be good filters but a little pricey in my opinion.

Help a lot, will order them again.

Perfect size and great for allergies

I like these a lot and in fact after my new HVAC system was installed the technician recommended Filtrete Filters BECAUSE THEY HAVE REALLY GOOD AIR FLOW !

High quality filters, easy to install. Good value for the money! Will buy again!

I have been using this filters since 2020 and have been satisfied with them. I ensure to replace them per the schedule since they can be more air flow restrictive.

These filters fit properly, and work as advertised.
