Research On Refills For Vent Stack Filters Often Called Stink Pipe Filters

When you purchase replacement chemicals for your odor eliminator filters for rooftop sewer or septic tank vent stacks, first check which chemicals are in the media and which odors they mask or absorb. The vent stack is often called a stink pipe because it is designed to vent all sewer gas. After all, that is the reason you installed the filter. You want to buy a chemical media that functions through oxidation followed by adsorption and absorption. The replacement chemical's formula should have Hydrogen Sulfide as its primary target. Ammonia is the second target. Hydrogen Sulfide is most often referred to as H2S (rotten egg odors) and the secondary target is Ammonia (urine odors). In many situations, Ammonia is present at problematic levels. H2S odors present in vent stacks from sewers and septic tanks are another problem.

Pellets of Chlorine Dioxide, referred to as ClO2, does a great job on H2S and other bad odors. It does not react with Ammonia as a chlorinating agent nor as an oxidant. This is a strong, positive reason to search for a media that can remove Ammonia. There is a chemical formula that can remove Ammonia at a fraction of the cost of other chemical removal formulas. Search it out and you will find it will remove other Nitrogen based odors as well. It also will remove primary and secondary amines. This means it is better or equal to the media in you current filter. It does not clump as does charcoal and in field tests , it has worked in vent stack filters for five years before the chemical media needed to be replaced.

There are numerous odor eliminating chemical medias on the market today. The best ones use a combination of the same chemical formula. This type of odor eliminator chemical media is the best for refills. They all have refill bags that are designed to fit 2-inch, 3-inch, and 4-inch vent stack filters. The pricing is very competitive on all odor eliminator chemical media made with these formulas, and they are superior products. Unlike straight carbon based media these products are not affected by the weather.

Always wear gloves when you remove the any existing media, and dispose of it in a plastic bag that you can seal. When you are installing any new refills always place them in the filter vent housing as directed by the manufacturer of the chemical. Find a chemical media made with materials that can be spaded into your plant beds; they can be a great fertilizer. Let's help make this island home, our earth, GREEN!

Do not open the polyester refill bag that any chemical media comes in. They all adjust to fit the shape of the housing of your filter.
