Merv 13 Filter Material for Air Filters (16Ft²), Air Particles, Clean Living Basic Dust Small as 0.3 Microns, Efficiency Breathable DIY Design (16 Square Feet)

Perfect for anything with a fan. Just cut to fit the intake side of the fan and the air exiting the fan will be cleaner. I have used it on a box fane and it collects an amazing amount of dust. I have also been using it on two window air conditioners to filter the air. I don't know why I didn't think of this years ago but it is absolutely fantastic and I will continue to do this for the rest of my life. Try it and you will be amazed.

Works well to reduce airborne particulates by filtration. I have noticed a decrease in respiratory issues after use.

I installed these at my inlet intake to see if I could prevent cat and dog hair depositing in our drain pan or bypassing our regular pleated filter to deposit on our Heat Pumps coils. To make this work, I had to cut to size then tape the back end on the metal intake vent. Then I screwed the vent back in place and vaccuumed the outside periodically. After 6 months I was blow away. Picture one is the back of this filter cloth. Picture two as I am removing to replace is a picture of the front. (The original color of the filter cloth is bright white) The last picture is of our drip tray, which remained pristine. Our normal filter was a bit dirty too, but I got 6 months out of it and the coils to the heat pump are perfect. The filter cloth never moved when the unit was on, stayed in place perfectly. Highly recommended.

Funciona pero reduce la fluidos del aire considerablemente

I can literally see pores through by holding it up to the light. It does not look Merv 13 at all. I have no idea it's just very thin

We have been using the more expensive antimicrobial mesh filters for our RV a/c units. With 3 units it was costing a bit to replace them every 90 days since in sunny Florida the units run quite a bit. The filters that come with the A/C units are practically worthless BUT, if you cut this material to go over the original filters it works great at a fraction of the cost is the more expensive mesh filters.

Thick material. Good filter. Not much will get through this. Cut to size for your needs. A generous amount for the price.

added a piece of this in front of each of my return grills because we have lots of dogs that love to shed hair. Was tired of all the dog hair that was collecting on our a-coil upstairs. Somehow it was getting past our filter system. I looked the other day and there wasn't near as much as expected after installing these. I installed these by cutting my pieces and using small magnets to hold them in place which works really well.

I used this to revive an old Rigid air filter system. OEM filters are no longer available so this is a practical alternative.

they worked great

I live in a mobile home and the furnace only uses a certain kind of because of the size of furnace…..they suck(pun intended) they are terrible….this one is fantastic cut to size ….allergen certified…dander….smoke…hair….this one gets it all……best I’ve used…I recommend

The product is fine. Curious why the listing shows 32 square feet in the main description but then 16 square feet listed as the colour. Why? The piece I got was 16 ft2.
