Review on 🌿 EnviroSupply 4x8 Activated Carbon: Premium Coconut Shell Bulk Charcoal for Gas Purification, Air Freshening, Odor Elimination, and Deodorizer Vapor Phase Applications - 5lb Bag (80oz) by Kyle Tran

As usual, the goods arrived a day earlier. This charcoal appears to be of good quality. The granule size is slightly larger than the activated carbon replaced in the 6" × 18" filter, but matches the small dust size. I was able to freely fill a small filter, its volume is about 1565 cubic centimeters. Advertised at 5.5 pounds. The packaging only says 5 kg. 5.5 pounds would have filled the filter canister better as I had to leave it loosely packed. It's nice to see the NSF label on the solid packaging, hopefully it's actually certified material. I use the filter 24 hours a day, 7 days a week to decontaminate my living and sleeping areas. As soon as I started the fan at 400cfm I could smell burnt plant matter. This tells me that at 400-600°C the charcoal was not properly processed and no catalyst was added. I personally cannot recommend this supposed "activated charcoal" and believe that it is not NSF certified. After a week of use, the product seems to feel good.
