FPL07-2PK-24 10x20x1 Flat Pan Filter - Quantity 24

Been searching high and low for a polyester filter that flows as free as possible. Too many people get hung up on what the filter will filter out and forget that a furnace has to breath too. Otherwise the blower motor works too hard and is more apt to burn out as well as the a/c a-coil being more prone to freeze up. Do some internet research. My furnace has a static pressure issue ( more furnaces do than people realize) and wanted something better than the spun fiberglass filters that dont really filter- you can pour salt right thru them. This filter fits the bill... The merv 5 rating (3m equivelant of 100 in their rating system) is the only merv 5 that the big box stores sell in my area. Just wish they would go back to the standard 'boxed' framework that seals so much better. Give them a try and see if you dont get better airflow thru your discharge vents and save on your bill sinc ethe blower dosent have to work so hard.

[This review was collected as part of a promotion.] Installed this filter two weeks ago and have seen a definite improvement over the better rated ones, seems like my a/c has shorter run cycles and my house is as cool as before. I will use this level of filter from now on. Also the last two weeks we have had record setting temperatures almost each day.

I have been buying these filters for 10 years and have loved the quality, what they catch and the cost for a 3 pack. I always get two packs to have 3 changes. I change them between 2 to 3 months apart regularly. However; since the change that was made in their actual "1" inch width NOT so satisfied with the 3 Pack anymore. They are so thin they whistle ALL the time and it is so annoying when trying to sleep. I haven't given up on Filtrete yet, I returned the unopen packs I had and purchased a 2 pack 1085 Micro Allergen Extra with a true "1" inch edge/rim. I sure hope they are quiet like the other filters used to be when they were thicker. Unfortunately they are twice as expensive. Love to see you change the thickness back and even you had to raise the cost just a little.

I bought these filters at Lowes looking at them and seeing the air flow arrows they look backwards because the air filter supports are facing intake, never seen that before.This AM WOKE TO A whistling sound coming from intake, not happy. I AM taking them back.

[This review was collected as part of a promotion.] This is the first time I have purchases this style filter (does not have boxed edge). I have been using Filtrete since we moved into our house 10 years ago. I question the flow arrow on the filter. If you install it as recommended the filter element does not have support as the plastic grid is on the upstream side. I am concerned that the filter element will be pulled out of the frame. I cannot recommend this product as I just installed the filters. I will probably just replace them to have peace of mind.

First of all, the design is poor. The reinforcing supports are on the "upwind side" of the filter, which means the airflow would be trying to pull the filter off the supports. Almost all other manufacturers put the support on the "downwind side". Also, I bought the 12" X 12" filter which is so skimpy on the filtration. The cardboard support frame is tapered and wide so that the filter itself is only 9" X 9". Doing the math, the filter surface area is actually only 2/3 of what it should be and creates a lot of wind noise - trying to draw a lot of air flow through a small area. Plus the filter frame itself is slightyly undersized and allows A LOT of unfiltered air to go around the edges. I had to use cellophane tape to keep the filter in place and prevent air from going around the edges. I''ve seen this same poor design and undersized filter pleats on other 3M filters. They charge way too much for such a poor product. I will no longer use them in my house - they're useless and overpriced.

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.

Bought 3 at Fleet Farm to try as were on sale. Air flow was not good and filter pulled away from frame. Shouldn't support be on the opposite side? Are the air flow arrows printed wrong? Replaced with regular brand I was using. Not worth the worry to ruin a furnace. Threw the other 2 away. Waste of money. Sorry, would NOT recommend.

I have been buying these Basic 3M filters for years and when we built a new home, I continued to use this filter. Recently the look of the filters changed so I knew it had been re-engineered. Then the air returns with the new filters became very noisy and the filters were nearly being sucked into the duct. The cardboard seemed to be flimsy - (didn't take a micrometer to it but wish I had). The new style filters are noticeably smaller in both directions. Next time you re-engineer to cut costs, remember to account for the varying size of the lip on air return duct openings. Not all are 1".

Loyal Filtrete user. Changes to this one are disappointing. Now I see the comments about the air-flow arrows appearing to be wrong and how flimsy they fit in the frame. All true. Don't think it will hold up long with summer runtimes of our a/c. Disappointed.
