The Honeywell 32004078-003 offers an unmatched degree of protection against gases, smells, chemicals, and VOCs thanks to the finest media in the business and outstanding filter design. Instead of the inferior carbon made from coconut shells that most people use, the media is made of the highest-grade activated carbon from bituminous coal. VOCs are eliminated from the air by using alumina pellets loaded with potassium permanganate. The CPZ filter's design provides very little air restriction while enabling excellent interaction between the air and the filtering material. All F111C and F116 Honeywell model types are compatible with this part. This is a direct replacement for 32004078-001. Dimensions: 21.75" (L) x 11.5" (W.) x 11.5" (H).
