I've been using pleated 3M filters in my furnaces since I built my home in 1996 . I have gradually upgraded to higher MPR ratings as they have become available and am now using the 2800 healthy living filter in both of my systems . I'm extremely happy with this product and both subjective and objective findings suggest that these are high-efficiency filters . As an allergy sufferer I've noticed greatly diminished symptoms and moreover surface dust on furniture is much reduced . I also have a Dylos particulate counter that confirms much reduced dust levels. I was initially concerned that the 2800 filter would clog more readily and need more frequent replacement then the lower rated filters . This has not been the case however , as airflow remains excellent which attests to the high capacity of these filters .

[This review was collected as part of a promotion.] I have used this 4" filter since replacing our furnace (used 1" Filtrete filters before this). Love how it cleans the air, especially since we have 2 Balinese cats. The only "con" about this filter is how hard it is to remove from the furnace. I finally figured out a way to attach a string to the front of the filter so that it's an easy pull-out when it needs to be changed. Perhaps Filtrete could come up with something like this, or 2 finger holes for easy removal.

It was time to change the filter and reorder. I like to keep a couple on hand.

Great and not our size but was able to fit to size!
