Its mesh bag design allows quick, tool-free replacement without removing the filter, ensuring continuous performance and a fresh environment with minimal effort. ## Description Product description The OdorHog eliminates odors as they exit the plumbing vent stack, allowing you to enjoy an odor free back yard/patio. Here is a list of our FAQs The OdorHog carbon filter installs directly onto plastic PVC or ABS vent pipes on the roof. The majority of homes and buildings today have plastic pipes. Filters for metal, copper or cast iron pipes are available on our website. OdorHogs are made from heavy duty Schedule 40 PVC and ABS. They are made to stand up to the harshest climates and storm conditions. They are not made from thin, plastic injection molded parts from China like other filters. OdorHogs come with the highest quality pelleted carbon in a replaceable, breathable mesh bag, that can be easily changed out while the filter remains on the vent stack (no dirty mess, like change outs on other filters). OdorHog activated carbon is formulated for the H2S molecule and made to last. We include a freeze protectant to keep the carbon from freezing in cold climates. The additive is similar to salting your walk or driveway after a freeze or snow. It coats the carbon and keeps it from sticking together. Slip on cuffs require no glue or tools. Snug it on and give it a twist. Proudly made in the USA. OdorHog has been in business for over 19 years and is the leader in vent pipe filters. Contact Odorhog with any questions. We're also happy to help with sizing questions. Review: Amazing product! - this is truly an amazing thing! I never write reviews, but I had to for this. I have a waterless toilet in my tiny house and the toilet has to be vented. The only way I could do so was to vent it out the front and up - and it had a constant odor coming from all the pipes from the beginning all the way to the top. flies would hover around it and that combined with the odor just meant that we couldn’t even sit out in the front yard at all. I saw this advertised so I thought I’d give it a try. I purchased just the bag. I took the 3 inch pipe apart that comes out from the front of the house and I just slid this right inside the pipe, put the pipe back together.... AND NOW after just the first few days, the ODOR is GONE! it is truly unbelievable! I don’t care if the filter lasts a year or a few months... I’m going to get a dozen and have them on hand!

I’m going to get a dozen and have them on hand! ### ⭐⭐⭐⭐⭐ Work great *by D***E on September 26, 2024* Bought to replace for my odor hog vent cover and they work perfect ### ⭐⭐⭐⭐ Works perfectly for the intended purpose of eliminating the smell. *by K***R on February 5, 2026* Like the title says this works perfectly at removing the smell but if you live in a very cold climate these bags can freeze solid and block your air vent. I live in MA and I made it through the first winter without any issues but the second winter the bottom portion froze solid blocking my air vent which causes problems when you flush a toilet. I had to hire a roofer to get on a snow covered roof at the time of failure to remove it. The bag was 2.5 years old and I planned to replace in the spring but the freeze beat me to it. Maybe it would be a good idea to remove it in the Fall. Happy with my purchase just be aware of the freeze risk. ## Frequently Bought Together - OdorHog Activated Carbon in Mesh Replacement Filter Bag, Fits 4-Inch OdorHog - OdorHog Vent Stack Pipe Filter 4 Sizes, Black ABS with Mushroom Cap, Removes Outdoor Septic and Sewer Odors (3.0-inch) - Septic Tank Treatment - 1 Year Supply of Septic Safe Dissolvable Easy Flush Live Bacteria Packets (12 Count) - Best Way to Prevent Expensive Sewage Backups - Made in USA --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/214905165-odorhog-activated-carbon-in-mesh-replacement-filter-bag-fits-4](https://www.desertcart.be/products/214905165-odorhog-activated-carbon-in-mesh-replacement-filter-bag-fits-4) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-06-11*
