Filtrete 20x24x1, AC Furnace Air Filter, MPR 1900, Healthy Living Ultimate Allergen, 6-Pack (exact dimensions 19.81 x 23.81 x 0.78)

Loving these so far and I have them set to auto-ship every 3 months so I don’t have to remember to change the filter. These have a terrific rating, are easy to install, and received excellent scores on Consumer Reports. Looking forward to buying more.

For me the 1900s are a good balance of price and function. I paid 40 dollars more this year but that only comes out to an extra 3 bucks or so per month. Worth it to help clean the air we breathe.

Excellent Design that Results in Relatively Low Pressure Drop for High Filtration in 1 Filter

Good product, I really like the way it filters the air.

These 3M filters are far and away my favorite to use. No whistling, or other signs that my system is struggling to move air through, and they filter all manner of awful filth.

Product does not filter out cigarette smoke as advertised. Smoke is still strong coming through vents. Sadly disappointed. I really need something to work. My downstairs neighbor doesnt care what hes doing to my granddaughter, service animal or myself. Im going to keep looking.

The family was able to quite taking allergy medicine after these were install for a couple months.

Originally I thought high end filter would get dirty/blocked easily due to high filter performance. But there is one things that I didnt consider. With the same size 14x24x1. 1900 would have larger filter area comparing to one I used before. (3M Clean Living 300) Roughly around 4 times larger, because clean living 300 filter fold around 11 times, while the filter of 1900 fold at least 40 times.

great product. exactly what is described!

Great
