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.

My wife has had "4" open heart surgeries, 2nd pace-maker defibultor so the quality of the air in our home is very important to us. We use Filtrete filters. They are an excellent product to say the very least. We keep a spotless home and change the air filters every 3 months. I am amazed how much they catch dust, pollens etc. as our home has been taken care of meticulously. It amazes us, again as our home is very clean. The filters do an exceptional job in clean the air. My only wish they be more responsible in price but it is what it is. Thank you for making sure a wonderful product. Just wished they are a little more reasonable in price.

The way our air system is set up, we have a 1200 filter installed just under our unit, but we also have another filter mounted in the door. The air is sucked in through the door filter first and then up through the one in the unit. We LOVE this set up and we LOVE using Filtrete filters. With my husband's asthma and allergies I don't know what we would do without them! Thank you Filtrete!

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.

My HVAC of 30 years brother told me to purchase these filters vs the little 5 pack ones in order to cut down on the allergens and dust in the house. Monthly I would always change the cheap ones too, but let me say that this Filterate filter is really helping our allergies and furniture dust. I plan on always using them now but often the local is sold out of them. But eventually I get one. I like that there is an area for you to write the installation date on the filter and then take the provided sticker and stick it to your calendar for follow-up.

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 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.

After my electronic air filter system failed, I decided to to try the Filtrete Air Filter. (1550, 4"). I have been using it for the last four years. It seems to work every bit as as well as the expensive electronic system. I thought we would notice more dust in the house, but that is not the case!!

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.

Decided to try this filter to see if it could remove household dust. For the last 9 years I have used the 1085 filters but they let too much dust through them. After the merry maids finished I would change the filter then test for dust for a week. These filters allowed dust to accumulate. Not good!
