Review on 🌬️ Whirlpool 8171434K Air Purifier Active Carbon Pre-Filters - 4-Pack (Large) - Fit AP51030K, AP45030K, APR45130L, WP500 - 18x16.5 inch by Michael Cox

I bought this Hepa + Charcoal combo pack. Conducted by Revain himself. As others have noted in the comments and photos, the charcoal filter is very thin and easy to see through if held up to a light. I was skeptical that what I received was a genuine Swirl brand for two reasons: 1) The listing does not say 'genuine' compared to the HEPA filter listing which does. 2) Compared to the Hepa box, the activated carbon filter box looked a little "wrong". Even the whirlpool logo is completely pixelated. Looks like someone cut and pasted their logo from the website. So I figured the carbon filter might be fake so I called Whirlpool and bought it direct from them. Guess that's exactly the same. Whirlpool told me on the phone that they are "leaving the air purification business" and are now licensing their name to a foreign company that makes filters differently. This explains the change in quality and the confusion people had with it. This makes them real "whirlpools". But the hot tub is junk now.
