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.

[This review was collected as part of a promotion.] The Air Flow direction has been changed (redesigned maybe) with the a stronger stretched wires first and the pleated material second. In addition, the paper each is reversed. I installed them (I have two AC systems) and could see they worked just fine. My question is was this redesigned to improve performance or was this a mistake in the manufacturing process? Can you explain this new design?

I was hoping that I'd just bought a bad package of these but after reading reviews of other long time users, it looks like the quality has really dropped on these. I've been using this product for about 10 years and have been very happy with them. This last package contained filters that are too small to fit up in my ceiling intake. They drop down onto the grill and the air can be pulled up around the filter instead of going through it. If this is what I find in the store again, I'll be shopping for a different filter.

The Basic air filter is poorly designed, having the wire support on the intake side of the filter material. It used to be on the back side, and whoever made this change must have made a mistake. A strong airflow can pull the filter material off the support wires, and into the blower, if the filter is installed per the arrows on the frame of the filter. I'll turn my filters over, so the support wires are on the outgoing side. Next time, I won't buy 3M filters.

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.

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.

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 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.

[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.
