Bought this a month ago after having my unit replaced. I was suffering with severe allergies due to the ductwork and unit being replaced by a very sloppy company, so I decided to give it a shot (it had its work cut out for it) I am replacing it today. Usually lasts a lot longer but my home was contaminated severely due to the negligence of our ac repair company!

[This review was collected as part of a promotion.] I have two cats, two Labradors, two teenage daughters and myself in my house. There is always dust, dirt &/or dander in the house no matter how frequently I clean. Having this Healthy Living filter in my house gives me peace of mind.

[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.

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!

I used to use those half-inch wide throw-away $2 fiberglass filters on my old furnace. But when I invested in a high efficiency furnace, I decided to go with better air quality in the house, too. Boy did I get it. My Filtrete 4-inch wide furnace filter traps a lot of stuff I don't want in the furnace, no less the air I breathe. I have a dog, and though I keep her groomed, there is still dog hair left over; the filter is doing a great job filtering out dog hair that would otherwise enter the furnace air supply. It's a comfort knowing my home is a little cleaner and the air is a lot more breathable with a high quality Filtrete filter.

Filtrete filters are the best. I've tried cheaper brands and even though the measurements on the box are what I need, they don't fit my furnace correctly. They leave too much space. The Filtrete filters have a snug fit and really catch all the dirt. I would totally recommend them.

I have used Filtrete filters for years! The 4" filter fits inside the frame of a disconnected electronic filter system that was always problematic. Filtrete filters perform better than the electronic system ever did and provide a superior return on my investment.

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.

Good filter. Although it is advertised as lasting up to 12 months, I feel the need to replace it every 2-3 months. I have a VERY difficult time removing it from air cleaner, as there are no holes in the filter in which to insert your fingers to grab it for removal. A simple design change would make it more user-friendly. I've found that I have to use a knife to cut a hole in the filter cardboard to have something to hold on to. Also, the cardboard strips on the sides usually get caught in my air cleaner, so as I'm removing the filter, I really have to pull hard, tearing the side strips, as I remove the filter.

[This review was collected as part of a promotion.] This is absolutely the best air filter I have found for my home. We had some minor construction in our kitchen, Sheetrock, taping and sanding. Dust was everywhere. Installed one of these Filtrete Healthy living filters and the air quality improved within minutes. I change my filter every season, the Healthy Living filters trap so much dust, dander and who knows what else. Great product worth the price!
