Great replacement for electronic filter

[This review was collected as part of a promotion.] My electronic filter quit! What to do? Your 25x24x4 was a perfect fit and works better!
I would recommend this to a friend!

Whiteness Helps You See Performance
on October 5, 2010
Posted by: FilterFitter
from Southern Illinois

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.
I would recommend this to a friend!

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.
I would recommend this to a friend!

I bought this a few months ago and its amazing the difference this product makes vs. competitors...It's like night and day. Breathing the air in your home after installing this makes it worth every penny.

My Go-To Filter
on March 21, 2016
Posted by: Blue Stripe
from Russellville, AR
Gender:Male
This is a very good quality filter. It does a fantastic job of filtering out allergens and dust. With routine filter reminders from Filtrete, the heating/AC unit does not have to work as hard either.

[This review was collected as part of a promotion.] This filter works as advertised, and is a great value. I don't try any others at this point.

Still dust
on September 23, 2016

I have a continuous problem with dust. The duct work has been cleaned sometime back, however the dust problem continues. While not as bad as it use to be, prior to using Filtrete, it still exists. I have been purchasing the 1200 filters. Would appreciate any recommendations.
No, I would not recommend this to a friend.
