Customer Reviews
Filtrete™ Basic Air Filters is rated 3.3 out of 5 by 86.
Rated 1 out of 5 by from New design is awful I used to really like the Filtrete basic filters. The ones that had a full box (not tapered) cardboard frame, with the metal wiring in a criss-cross pattern across the back. They were sturdy and held together well over 3 months of use. With the full box frame, they also fit tightly in my vent grills, which was especially important for my upstairs ones in the ceiling. They new design has a tapered frame and got rid of the wire mesh support and now uses a flimsy plastic support that is on the front-facing side -- NOT on the back facing the furnace, where the support should be in order to keep pieces of filter material from flowing into the furnace. Another problem with the new design is the plastic support material creates a super annoying whistling sound in some of my air intake vents. If 3M does not go back to the former design and quality, I will be finding a new brand of filter to use in my home and all of my rental properties.

Rated 2 out of 5 by from BAD DESIGN I bought two of these about Lamont ago so I would have them on hand and ready to go. Just got them out and noticed the air flow arrow. Others have commented it looks like it's going the wrong way. The other problem is because the cardboard frame is beveled or slanting out it does not go in the furnace easily and i think it would kink if forced. I am not going to take the chance of installing these and have one sucked into my fan. Money wasted and I won't buy again. I hope no one lost their job because of the air flow. Maybe they are working from home and are making them on the kitchen table. Seriously 3M should change back.

Rated 3 out of 5 by from new design I do not like the new design of the 1085 filter that I bought today. It had a cardboard support across the back of the filter that is very flimsy and certainly will do nothing to prevent the filter from bending inward due to air intake from the heater. It may even rip and bits may get sucked into my heater. No thanks. I returned it. Thank goodness there were a few of the old style still in the store so I bought them. Please go back to the previous style without those cardboard supports.

Rated 1 out of 5 by from Poor fit I purchased 20x30x1 filters for my 2 HVAC systems and tried to install them in factory manufactured return air grills. I removed the old 20x30x1 hardware store branded filters and attempted to install the new Filtrete basic ones. They were so tight I had to force them into the opening causing them to bow, allowing the air to go around the filters. I ended going back to the hardware store and purchase the cheaper brand that fit properly. I had this same issue at another property I own. Picture it the filter that fits correctly.

Rated 1 out of 5 by from Wish frame was full. I wish the frame on these filters was full instead of being so thin. It does make a difference, especially noise-wise when the unit comes on and turns off.

Rated 4 out of 5 by from Good Filter My husband came home with this air filter. I changed it out and watched it over the last month. It works good. A little heavy in thickness so not sure how well it filters through but it does the job.

Rated 1 out of 5 by from Not true to size I bought two different sizes (12x24x1 and 16x20x1). Both sizes are slightly larger than the size stated and will not fit in the openings. Very poor quality.

Rated 4 out of 5 by from Restricted Air Flow Why is there so much cardboard restricting the airflow? I remove all crisscrossed cardboard from the middle of both sides and they work fine with better airflow.
