4x8 Activated Carbon (Virgin Coconut Shell), Bulk Charcoal for Gas, Air Purification, Odor Removal, Deodorizer Vapor Phase Applications - 5 Pound Bag (80 Ounces)

My second purchase.

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!

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...

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.

Refilled our Austin Air filter with this. It worked perfect and the air smells clean coming out of it again. It took about half the pail to fill the filter.

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

I am using this for an air scrubber on my 3D printer, and although I have not installed it yet, in testing, it seems to be working OK so far. The particles are about the size of coco pebbles cereal so they can be held with a pretty coarse mesh as you can see in the pic. I had to wash them in RO water and dry them in a veggie bag before I could use them - to get rid of the dust.

Ordered the Envirosupply 4x8 activated Carbon. 1lb.The bag opened up with little to no dust. I still rinsed a sample and got very little dust off. Rinsing probably wasn’t necessary.The screen size is ideal for air filtration which is what I need.It’s to coarse for ideal water filtration. If that’s your need, buy the finer screen.
