Whynter ARC-FIL-3M 3M Filter for ARC-14S, ARC-14SH and ARC-143MX

Works exactly as advertised. It does a good job of filtering out dust and other impurities from the air, although it doesn't reduce odor as much as the carbon filters. But that's to be expected, plus having a hepa-filter with carbon pre-filters would more than take care of this problem (as I have). I recommend this product.

Earlier items sold under this name may not have been authentic but the product I received, shipped and sold by Amazon, are legit. Perfect cut, perfect sizing, quality is better than the OEM carbon filter that was included with the AC.

Fits right, but there is no way for the user to test efficacy thus its actual value is a crapshoot. At least it does not emit any onerous odor into the air stream in cooling or circulation-only modes. Wholly a "take-it-on-faith" proposition.

I have used this for about 2 summers. It needs to be cleaned about every 3 months of use and washes off easily with plain water. Stops most dust/lint. The coils in my unit still look new. It also helps hold the flimsy carbon filter in place.

Do not buy this item! It does not work with the machine. It is false advertisememt. It is a poor fit and a poor size.

My old filter was finally tore in half. On a whim, I looked on Amazon … and sure enough, they had them. Now I will order regularly instead of trying to clean the old filter.

Well first off it fit. Reading some reviews about size, I was a bit concerned. It was the anti microbial filter as stated. Turning on the a/c now.

Works great, just wish it was cheaper. I spray a little colloidal silver on it, let it dry and use!
