4x8 Coconut Shell Activated Carbon | Air & Odor Filter GAC Media, 20 Pounds

Very pleased with this carbon - I reached out to Joe as he gave his phone number in a response to a question and sure enough he answered the phone and answered all my questions about activated carbon and it's use in 3D printing. They sell to large scale industrial customers for VOC filtering on 3D printing & laser cutters, so this is the right material for the job. The carbon I received seems very nice - pretty uniform granule size and very clean. No dust on my hands from handing it. I run it on top of a HEPA with a prefilter, and after a week of using it I pounded out the filter to see what came out. Very small amount of "dust", enough to where I'm really not concerned with it degrading flow. Actually, 20mm of this flows quite a bit better than the 10mm thick HEPA of the same surface area I have. Very pleased to have found a quality source!

Great. I finally found some activated carbon of the right size! Usually it's too fine for most air cleaners, too fine because it's intended for use with water. The fine stuff just wouldn't pass enough air, too restrictive. I've been using it to renew old air cleaner units and it works just perfect. I will buy again! thank you

Product arrived a day early as usual. This carbon looks to be of good quality. The size of the granules are slightly larger than the carbon being replaced in a 6"×18 " filter but consistent in size with a low dust content. I was able to fill the one small filter loosely the volume it holds is approximately 1565 cubic centimetres. Advertised as 5.5 lb. It is only labeled as 5 lb on the package. 5.5 lbs would have filled the filter canister better as I had to leave it loosely packed. Good to see the NSF label on the sturdy packaging, I hope it is actually a certified material. I run a filter 24-7 to scrub pollutants in my living and sleeping areas. Once I started the 400 CFM fan One could smell the odor of burned plant material. This tells me the carbon has not been processed correctly 400-600 C and no catalist added. I personally can not recommend this supposedly "activated carbon" and believe to be not NSF certified. After weeks of use the product seems to be holding its own nicely...

great product being used in my ash trays

The small carbon filter in the bambu printer doesn't last more than a week and you begin to smell the PLA. I added a heavy duty filter to the back of my bambu 3D printer to remove smells. I filled the inside with this carbon and attached a HEPA filter to the back. It works wonders! I don't smell anything at all and it's been close too 3 months. I need to test VOCs to see how much is in the air.

This is an easy way to keep air dry and clean. I can't say how it smells because no odor lasts with a bag of carbon open. I put bowls of it out in the kitchen bathroom basement. It's a good value for all that it does. It helps with galvanized air too. It's carbon it can be dirty but it is just the dust of it. I put it in the to keep it up.

Bought this to make air purifiers for our Cat litter boxes. These granules are very nice big chunks and work wonders at absorbing odors. I have made little baggies and placed them all around our house, I like not having to use fragrance to mask our everyday smells.

decent. didn't work very well in an air scrubber I think you would need a finer product .this is a bit too corse .. probably works much better for liquid filtering applications.
