Been using for over 16 years!

Bought my home new in 2000 and to this day its the only filter I've ever used and trust. I change about every 3 months (more often in hot summers and less in mild spring when not in use). Highly recommend this product. My brother and mother also use 3M filters for many years in there homes too.

Whiteness Helps You See Performance

The filter does a great job as evidenced by how infrequently we need to dust the house, and by how little dust and lint are on the blower fan blades of the AC/furnace. Beyone performance, one attibute I like is that the filter is super bright and white out of the package. Later when you remove it, you'll see how gray it has become from catching all the particles in the air. Separately, if the filter comes out curved instead of straight, you've left it in too long and were reducing the efficiency of your system. The reminder stickers help keep you on schedule.
