We purchased this filter for the first last year. It is an amazing filter. Product does a great job filtering out dust in our home. You can actually see the difference in the minimal amount of dust in the house. It's a great product. Would recommend to any body needing a filter.

I've been installing this filter in our furnace since it became available. It not only produced a cleaner home interior (our house was built in 1913) but also keeps the motor/fan and its enclosure cleaner thereby saving major and expensive mechanical furnace repairs/replacements!

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!

I've been using this type filter almost 3 months, and I've got to tell you that it's a great improvement over reusable filters that I was using. You can see all of the particles it collected...yes, it is DIRTY! I couldn't really see the dirt on the washable ones. I've noticed that there is less dust collecting in the house' big plus! Haven't noticed reduction of airflow nor higher energy bills. I'll continue using this filter...a little expensive to me- but we'll worth it!

[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.

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.

I have been using the basic flat filters for several years. I always thought that as long as I changed or cleaned them every month they were just as good as the more expensive "Allergen Reduction" filters. Boy was I wrong. I decided to try a Filtrete Allergen Reduction filter because my eyes were constantly irritated and itchy, and on wet humid days I could smell that "wet dog" smell more often. I've been using the model 1200 filter for just over two months, and my eyes are not itchy and there has been NO wet dog smell. I have been very happy with this purchase; just wish I had tried them many years ago.

The Filtrete 1550 Allergy Reduction filter does a remarkable job in filtering out the seasonal mountain allergens that blow into our North Central TX home. We use fewer antihistamines since we have installed the high efficiency filters. Thank you, 3M.

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.

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! ;)
