Filtrete 10x20x1 AC Furnace Air Filter, MERV 12, MPR 1500, CERTIFIED asthma & allergy friendly, 3 Month Pleated 1-Inch Electrostatic Air Cleaning Filter, 6-Pack (Actual Size 9.81x19.81x0.78 in)

Well-made, top-quality, perfect fit, excellent filtering. Fantastic price. Purchased a years worth.

Have always used this brand but recently started purchasing this level of filtration. No problems so far with our system and it seems to be doing a better job with particles in the air. Fair price here with the subscription.

Excellent filtration and the maximum air resistance our small, cheap furnace can handle. Any higher filter rating than this and our furnace starts acting up after a month or less. I get a good 3 months out of these filters in our dusty and smoky Central Oregon. Price is crazy expensive though. The electrostatic attraction of the Filtrete material definitely makes a difference.

As always, I will check every package even though I am not using it at the moment to make sure everything is fine. Everything came intact and ready to use for when I use it genuine .

I have been buying these for several years. They always fit perfectly. It’s a value for my money. It has good build qualities build. They’re really sturdy. They don’t have a smell. My only complaint will be that I did buy the six pack and they’re not wrapped individually which that will last me a whole year and I’m afraid that they’re gonna get dust in there before I get to use them.

These are fine for my old Trane unit requiring a 20x25 filter. HOWEVER they do not fit in my new Trane XL17i that’s supposed to take a 20x25. For some reason, they are about 1/2 inch too long and the door for the filter area will not close all of the way. Another brand barely fits but works with a bit of effort. A great filter and it appears Trane may be the problem. That’s why five stars with a warning.

I used to buy filters, when I remembered, based on price and reviews. But an indoor cat, acouple of seasons of heavy smoke from wild fires and increased use of both the AC and the heater got me to thinking that price should be the least critical factor. After looking at a lot of filter specs and reviews and some on-line videos, I bought a 6 pack of the Filtrete 10x20x1 AC Furnace Air Filter, MERV 12, MPR 1500, CERTIFIED asthma & allergy etc. filters. At the end of summer, you could easily see how much more effective these filters are than the other brands we used. I just ordered a second box of six and I recommend them highly

This is the 5 or 6th time I have purchased the and I'll do it again when I get low again!!! They make a BIG difference in the dust levels. I change them every 2 months, without delay. They work.
