I WOULD BUY THESE AGAIN AND AGAIN THEY REALLY CUT DOWN ON ALLERGIES AND DUST IN MY HOUSE, THE WHOLE FAMILY HAS NOTICED

[This review was collected as part of a promotion.] For the price, this is a great buy for the value...highly recommend!

These are the best home filters I've used and they go a long way towards reducing the amount of pollen and dust in the air.

We have a relatively new construction and I'm always amazed at how dirty these get after a few months of use. That tells me they really work!

When my electronic filter stopped working I replaced the electronic filter with a 4" Filtrete and it worked great.

I have used Filtrete filters for many years and the best. I can tell when 3 months is up and needs replacing

i change it every 6 mos and motor compartment looks like new which is the point if your compartment is clean your motor is too

I get these because of my allergies. These really help. They don't make allergies go away but it sure does lessen the severity of the problems.

I've had no problems with the filters. I have used 1" lesser brands and had trouble with allergies. This filter is much better
