Wolverine Heavy Duty Septic Vent Pipe Carbon Filter 4"

Industrial Odor Control's patented heavy duty residential and commercial HD Wolverine Brand Septic Pipe Vent Carbon Filter (Patent # US 8,273,162) is as strong as it is functional. The HD is made of schedule 40 PVC. The HD residential Wolverine has a 2-inch fill port for easy carbon change-outs and is also the only residential filter on the market that has an built-in end-of-service-life indicator to let you know when to replace the media before the odors return. The HD residential and commercial Wolverine uses the same catalytic carbon as our commercial models, Norit Darco's Sulfursorb+, and offers up to 4.5 times the life of conventional activated carbons and a 30% longer life span than impregnated carbons.
