Filtrete 12x24x1 Air Filter, MPR 1500, MERV 12, Healthy Living Ultra-Allergen 3-Month Pleated 1-Inch Air Filters, 4 Filters

My friend needed these filters and I am happy to have been able to buy them in a large package. This will handle his furnace and A/C needs for approximately all of 2021. It makes things so much easier to get them in this package size.

Traps so much dust, I should replace them every 2 month

I’ve been using 3M allergen filters for many years. I want to make sure my house air is as free of dust and dander as I reasonably can, so I use these and change more often than recommend to insure they don’t draw down the effectiveness of my airflow (usually two months). Having them delivered right to my door at a competitive price is a huge convenience! No need to make a special trip to get them, and I get just the size I need.

The merv 12 filtration level may be a little too high for some furnaces. We installed these filters and went from a merv7 to 12 and a week later the blower motor is having problems. Possibly coincidental, but we put the old dusty ones back in and it stopped tripping the blower motor switch. We do have an older furnace and I think these are restricting air flow a little too well. Our hvac friend suggested not going higher than a merv 8. Hope this helps.

I was so impressed how fast delivery was and the packaging. The price was very competitive and overall best filter I have ever used. Will buy again

my allergies are much less for using these products. our hvac technicians notice they keep our surroundings dust free. only thing for older hvac units 10 years or more, like ours until we get a new unit, these filters make the unit work harder. sometime we have to resort to 30 day filters instead. these filters are remarkable and of awesome quality.

I would highly recommend this item. I use them in small classes that I have, and they are well liked by my students.

Functions well.

Filtrete is the brand of furnace filter I always buy. They work great, are easy to install and I dont have to worry about anything when I use them!

Sometimes they don’t fit and need to be smashed in, sometimes they do.
