Filtering units for removing odor from plumbing vent pipes, most often referred to as stink pipes by plumbers, are the best solution age old problem of stink coming out of the plumbing/septic tank roof vent. The vent is design to release gas to the outside air so the waste water can flow down the drains. What are the differences between the various manufacturers? They are all similar in appearance with the outer shell made of PVC and ABS design. Sweetfilter was epoxy coated Black. Sweetfilter, VentPure, and Peacemaker show they are registered. Sweetstack has one way off and on valves and cannot be sold in Minnesota. OdorHog is now available with solar powered exhaust fan. Is that an added part to fail? VentPure and SweetAir units have rain cap because their chemical medias must be protected from moisture.

All chemical medias are a mixture of Carbon with other additives. You have to check the chemistry, or be a chemist, to see which is really the best chemical. What the home owner is looking for is a chemical media whose primary target is Hydrogen Sulfide. Hydrogen Sulfide produces that rotten egg odor that any home owner is familiar with if they have any type plumbing problem. The secondary problem is the Ammonia which produces the urine odor.
