4mm Pellet Activated Carbon (Virgin Bituminous Coal), Premium Charcoal for Air Purification, Odor Control, Deodorizer, Vapor Phase Applications - Resealable 1 lb. Bag (455g)

Used this media to refresh the charcoal pellets in my kitchen hood filters. Perfect size & shape. Much cheaper than replacement filters.

Perfect for my needs. I used it as an air purifier and order control. Worked perfect for that. Totally worked.

This product is very standard for VOC filtering in 3d printers, and I use it in my Q1 Pro with a Nevermore filter. These pellets cannot escape the holder, so they work well for me. The price is a little high, but its worth it, as the bag will last quite a while. Only problem I have with it is that the CTC rating could be higher. For more industrial grade carbon pellets, the carbon tetrachloride percentage is higher, which makes for a higher rate of harmful organic compound absorption. This carbon is fine, with around 60%, but for a higher quality carbon they can be upwards of 80%.

These work well in cat litter.
