Use them for 3 months or more with great results every time.

Excellent product, haven't been sneezing as much since replacing filter.

Just purchased a 16x25x5 model for my furnace, and this does not fit.

Product is just as described not like some other inferior filters!

None better. Been using them for 6 years never a problem....

We have an older nonstandard plenum...Filtrete filter can easily be custom cut to desired size

A third of the price as compared to the pure air, does a great job capturing pet hair.

Removes much more than just dust from the air! Mold spores, pet dander.

Excellent air filter. Air in our house is crisp, clear, clean, and allergen free.

Have used these higher level filtration filters for over 4 yrs with fantastic performance.
