[Outline]

DC621 are sheets containing 70% impregnated activated carbon designed to remove ammonia odors.
In addition to the adsorption and recovery of solvents, this product is also effective in the removal of ammonia and amine odors which were previously difficult to remove using unimpregnated activated carbon alone.
Furthermore, improvements have been made in deodorizing performance with respect to substances including hydrogen sulfide, etc. making this product effective for removing household odors including garbage odors, etc., and it is perfect as a deodorizing filter material for air purifiers.
