Ratings & Reviews+

Filtrete Allergen Reduction 4" Filter, 16x25x4 is rated 4.6 out of 5 by 82.
Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from Help for an old house Our house is more than a century old (built in 1888). Dust particles were magnified in the light that streamed through the over-sized windows. Filtrete filters have given us new appreciation for floor to ceiling sunlight.

Rated 4 out of 5 by from Good filter but some issues We've been using your filters for many years and have had one recurring issue. The housing for the filter doesn't have a lot of wiggle room, but it requires and accepts a 4" filter, so while the filter usually slides in just fine, getting it out is a challenge. It's ok if I am disposing of the old one and installing a new filter, but if I have to pull it for any kind of service, it gets destroyed in the process of extraction and that gets expensive when I have to replace a minimally used filter. My furnace company has worked on the housing and done as much as possible to improve the opening. What I notice is that the cardboard framing that contains the filter does not fit tightly and in fact bulges even on a brand new filter. This frame is what gets caught both going in and coming out of the houing. I would appreciate any feedback you might have pertaining to this issue. I apologize for the long-winded e-mail, but I wanted to clearly describe the issue I have with what is otherwise a fine filter system. Thank you, Harry Saxe

Rated 5 out of 5 by from Best Filter on the Market!!! I HAVE searched and cannot find a better filter than Filtrete. Not only does it make a noticeable difference in the air quality of our home, it has literally saved our HVAC unit. As do most new construction homes, ours came with the standard 'builder grade' system. Coincidentally, we have had a lot of storms and power surges this past summer. When our system (along with seven others in our neighborhood) burnt out last month, we were miraculously able to replace only the compressor, as opposed to the whole system. Since it came at a bad time for us financially, we had to opt for replacing the compressor only. Our HVAC technician told us that had we not been using good filters and replacing them regularly, that would not have been an option. Even though we will eventually have to replace the whole unit, we now have some wiggle room and time to save up. Meanwhile, our 'builder grade' unit and Filtrete filters are functioning beautifully. Thank you, 3M!!! You saved our lives (quite possibly literally--from this Southern heat and humidity)and allowed us some time to research and save for a new HVAC unit down the road a bit.

Rated 5 out of 5 by from My air is cleaner for me and my dog now 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.
