Simple Air- Pleated Air Filter 20x20"x1" (12 Pack)

This filter is rated MERV 8 which is equivalent to FPR 4 or 5 if you are looking at the filters you usually see in your local home improvement store. If you use the Filtrete by 3M this is equivalent to the filter with Green Label or the MPR 600. This will attract Mold, spores, dust mite debris, cat and dog dander, hair spray, lint and dust. I am impressed with the solid constuction of the filter. The paper that was used is said to be water proof and it actually looks like a fabric to me. It looks like I can hose it off a couple of time before throwing it away. I have been using the Filtrete brand rated 1500 MPR so I was skeptical about using a lower rating filter but this new filter actually feels better. I have not noticed any dry throat during the night. I have also noticed that the heating does not kick in as often. It could be that I just have a cleaner filter or that a lower MERV rating allows more air circulation in the system.

These filters are a unique design and the thought behind them is solid but unfortunately they didn't fully hit the mark.First is what some reviewers are noting is noise. The filter media does not make any more noise than any other standard media I have used but the thin, high flow design allows more of your blower fan noise to emanate back through the vent and into the room. The noise has always been there, just muffled by other filters.The build quality on the filters is great. Materials are of good quality and the assembly seemed well above standard. It is American made which is one of the reasons I decided to try it. Its manufacture did not disappoint but the design/engineering is disappointing.Air flow is great when the filter is new and a significant increase in flow was noticed at the outlet but this diminished quickly as the filter pick up debris.The big problem is fit. The outer dimensions of the filter on both sizes I tried was undersized. This prevented a seal fit within the vent frame causing two issues. One, my vents are overhead so if the filter is not snug it wont stay in place when I let go of the filter to close the vent. This constant falling makes it difficult to center the filter in the frame. Second, the loose fit causes an air gap around the filter in the vent housing. This caused the filter to move and bend as the air pressure flows around the filter until it deforms enough to seal against the frame. The materials are rugged enough to take the abuse but it does not inspire confidence that air is not bypassing the filter at some point.

Ok, I bought a 2-pack to try and just checked the first one after 5 weeks of use and it still looks fairly good and I put it back in for a couple more weeks. I have a variable speed fan on my heating unit (HP w/ fossil fuel switch) and in the winter I have the fan set to "on/continuous" which allows the fan to run at about 20% speed to circulate the air constantly when not heating. A similar rated cardboard frame filter lasts about 1 month under these conditions in the heating months. For cooling, the fan is set back to auto.The filter definitely has more pleats as the company claims. The plastic framework holds up well, even though it bulges out toward the fan suction over time; but so due the others as they plug up. I had a cardboard frame filter buckle once after 5 weeks. I had to slip my fingers in to push the bulge back as I took it out or it would hang up on the ductwork top edge. If it had a stronger center support it might help.Anyhow I just ordered a pack of 12 and plan on using these in the future.

We recently bought our first house and the home inspector noticed that the previous owner installed the wrong air filter. Someone tried to cram a 16x25x1 filter into a 16x24x1 space. Not only was it wrong size, they installed it backwards too. No Bueno. I drove around town trying to find the correct sized filter but none of the big box home improvement stores stocked it. So I went to Amazon, looked through the different choices and settled on this one. It installed easily and fit perfectly. The next morning however my wife and I both woke up with chapped lips and a dry mouth/throat. This scenario has repeated itself daily since I installed this filter and created a new issue that I never experienced before. It has completely dried out the air in my house.

Found the frame of these filters bends under the vaccum of the furnace. Allowing particles to get past unfiltered. I have tried a total of 4 of them and after 1 1/2 to 2 months each, I found the same result. It's a great price for the type of filter, but the frame just doesn't cut it on our system. Also these need to be monitored as when they clog with dust, they will burn your blower motor up. Going back to our tried and true. We only use these types in the summer to help filter the pollen out.

Cheap, sturdy, and works well. I used to always purchase the regular filters you can get at your local hardware store. They were expensive, mostly cardboard, and creaked every time my HVAC turned on. These filters are much higher quality (and less expensive). They filter well, don't make any noise, and stack on each other while storing to minimize used space.

I try to change my furnace filters regularly and have tried a lot of different brands. When I noticed this item on Amazon it looked different than any filter I have used before. They seemed a little pricey, but I decided to give them a try. I found that they made way too much noise when the furnace was on. For that reason I went back to a more standard filter.

Yes, it flexes... but that's about all I can say about it. It actually flexes too much as it gets sucked into the duct a bit. Also--more importantly--within just a few short weeks it gets horribly LOUD... even when not dirty. Apparently the material used clogs up rapidly. I wanted to like it, but just couldn't stand the noise.
