14x20x1 Air Filter AIRx ODOR MERV 8 Carbon Pleated Air Filter - Made in the USA - Box of 6

Not nearly as good as Nordic Pure or other charcoal furnace filters. These became totally ineffective after just 2 weeks. There's not nearly as much charcoal embedded in them as with other brands. These furnace filters are of cheap generic design and quality. They lasted me half as long as charcoal filters I've bought from other makers.

These filters were nothing less than an excellent value when originally purchased in 2018, as their construction was nothing less than great. They are reinforced on both faces, and do not collapse under the force of airflow over time. In addition, they also have thin wire woven throughout the filtering material itself, further insuring the shape is retained for maximum filtering efficiency. They are also individually wrapped to assure they are completely clean when introduced into the ventilation system. Of all the types and brands of filters tested ( and I have tested quite a few ), these are the best in all areas, hands down; in short, they easily deserve a " 10 ", or 5 full stars. The downside is that the price for six ( 6 ) has increased some 50% over last years price, but that does not negate the quality of this item. If they decrease back to a more reasonable price , more will be purchased by this reviewer; if not, a different brand will be purchased. As good as these are, they have not cornered the market on quality.

The actual size air filters I needed was 15.5 x 15.5 x .75 (15 1/2 x 15 1/2 x 3/4) and the description states that is the actual size, and that the ordering size is 16 x 16 x 1 .. The filters I ordered came today and I was happy to finally have clean filtered air, but as I went to put the air filter in, it was not fitting properly.. I had to force the filter in place because the filter was a little to big.. The air filter that was sent was 15.75 x 15.75 x .75 (15 3/4 x 15 3/4 x 3/4) , order size 16 x 16 x 1.

The only complaint that I have with these filters is that they don't come in 2-inch thickness. 20x20x2 is what my filter box is sized for.

The previous owner of my house smoked. Running through several months of these has tremendously helped. I hope to switch back to less expensive non-carbon filters in a few months.

We got these filters because the new apartment we moved into either had smokers living here previously or someone under us smokes, but our clothes were picking up the smoke smell. The old filter, a cheap one installed a month ago, started out white and was jet black when we changed it. With the AIRx, I've stopped coughing every time the air turns on, so I think it's working.

Fits fine. Can't say I notice any reduction in odor, but there isn't much carbon in the filter (not the filters fault as it has to be thin by design). For less than the 3M filters at the biy box store, I will keep buying these.

Poor quality. Filter media didn't even go all the way to the cardboard frame

Waste of money as not effective for odor removal. Merv works! This does not!
