This air filter does a better job of trapping all the junk in the air of our house. It located in a very clean walk-in closet and we're at what it catches. Its especially effective during the spring pine tree pollen season

This filter was restrictive enough to cause my evaporator to start icing up. Should be labeled that a HVAC technician needs to adjust refrigerant charge or up the speed tap on blower motor.

[This review was collected as part of a promotion.] Best filter I've ever bought! This filter is worth the extra $. I notice less dust/particles in the house and when I change it, I can see it is picking up more than other filters.

I know this filter works because when I change it, within the 90 day recommended time, with its fine filter capabilities, it really does its job as the filter is grey with particles.

Put the model 16x25x4 in Bryant furnace, after one run the cardboard retaining material was sucked in and had to destroy it to get it out. As a 3M stockholder I am not happy\.

My 16"X25"X5" filter was 4 7/8 thick. It was about 1/2" too thick for my particular venting. Be sure to measure your filter box before ordering...........

I love the idea of cleaner air, but my furnace company told me I needed to change the setting on my furnace when I use a higher quality filter such as this one. This was unexpected news.

I love things that just work. You know; Do exactly what they're supposed to do. These filters do that. In the country, one cat, and clean fresh air. Not to mention clean and efficient work load for the central heat and AC unit. Thanks Filtrete
