Bought first one in October 2014... 3 adults, a 1 year old & 4 dogs live here so I wanted a good filter. I saw them on a home show so I tried them now they are the only ones for us. I am a 65 year young grandma & clean air is very portant especially for my grand-daughter. Love your product. Thanks Kathy Alexander

We live in the country, own a feedlot, have 3 kids and have 3 dogs. Needless to say, there is a lot of stuff in our air. My husband and 2 of our kids have respiratory issues. These filters have done a great job of keeping our system as clean as possible in this environment.

We used Filtrete furnace filters for years. A few months ago I made the mistake of being talked into trying a different brand because they were cheaper. What a mistake! The other brand jammed and bent when trying to insert it in the furnace and it simply didn't trap the dust like a Filtrete. Needless to say, we will only purchase Filterete brand filters in the future!

Had problems breathing, eyes itched, migraines nonstop. Finally went to an ears, nose, throat specialist and was diagnosed with numerous severe allergies. Started on medication but it was not doing the full job. We saw these filters and decided to try them. What a difference! I could not believe how dirty the filter was. The first time we replaced it after the three months which is recommended. We changed it monthly for three months following that than every two months for the next 3 changes. Each month it became a bit less dirty. We could not be happier with the cleaner air!

[This review was collected as part of a promotion.] My nephew stays with me from time to time. He has asthma, which seems to act up on high pollen days. We can have the windows up with the air off and he would need breathing treatments. A couple of minutes with the windows shut and the air being on, lil man is back to normal.

I have a household of 6 and all my children suffer with seasonal allergies. The great thing about this product is as soon as I change my filters my children feel relief within the day until the next time for change from their allergies. Also like clock work, when the filter is near time for change my children allergies will act up to remind me I need to change the filter. I have no complaint with this product! ;)

I use 16x20x4 inch MERV 12 filters from Filtrete because they have the best build quality of all the filter brands I have used. I just have an issue with the vague MERV rating for a particular filter. Filtrete uses their own rating system (1550 for example) and then I have to do some research to find the MERV rating.

I have been using Filtrete filters for about 11 years at my "retirement home". This is the last house I am buying my wife told me when we purchased this one. It is a small ranch and it is easy to keep up. I love the Filtrete filters because I hate to dust.

This is the best filter for keeping the animal allergens under control. I put in a new one in the furnace yesterday before relatives with dog allergies came over and they had no problems the entire evening. So great! Better, too, for us non allergy people to not be breathing in all those minute particles.

I bought this product because it was the right size to replace my Electronic Air Filter, that had died. I installed it and all seemed well. After about 1 month I noticed the A/C unit was running continuously and the temp in the house was going Up. I noticed that very little air was coming out of the vents. Turns out that the filter material had sort of Swollen-up and cut the width of the 'pleats' by more than half. Basically, it was like having a 30-day filter in your furnace for a year! After de-frosting the unit and mopping up all the water, all is now normal with a different filter. I would like my $30+ back please!
