Review: Best charcoal for refilling water filters - This is the right granule size to use for refilling activated charcoal water filters. Bought this to refill my Brita pitcher filters. Aquarium sized charcoal is too big, and charcoal powder is way too small. This product works great, easy to refill the cartridges because the charcoal pours freely, and there's a lot less dust than with other brands of activated charcoal. And of course the water tastes spectacular! Also comes in a 1 lb size. Review: Used for a water "finishing" filter on a commercial water distiller. - Washed charcoal to remove fines from the larger mesh grains, then wrapped in a drip coffee filter to "finish" water from a commercial water distiller. Improves taste, and removes volatile organics and chlorination byproducts that may come over condenser head with the distilled water. ## Features - Premium Coconut Shell Activated Carbon - Manufactured from high-quality renewable coconut shells, this 12x40 mesh activated carbon provides exceptional adsorption capacity for water filtration applications. - Designed for Water Filtration - Helps adsorb odors, discoloration, dissolved organic compounds, and many impurities to support cleaner, clearer water in a variety of filtration systems. - Industry-Standard 12x40 Mesh - The 12x40 mesh size provides an ideal balance of water flow and contact time for efficient filtration and dependable long-term performance. - Versatile Water Filter Media - Ideal for aquariums, whole-house water filters, reverse osmosis polishing systems, ponds, hydroponics, rainwater collection, laboratory filtration, and custom water filtration projects. - Professional-Quality Filtration Media - Suitable for residential, commercial, educational, and industrial applications where high-quality activated carbon is needed for dependable water purification performance. - Premium Coconut Shell 12x40 Mesh Granular Activated Carbon - 5 Pound Resealable Bag ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00XLZZGX2 | | Best Sellers Rank | #108,189 in Pet Supplies ( See Top 100 in Pet Supplies ) #1,715 in Aquarium Filter Accessories | | Brand | EnviroSupply | | Brand Name | EnviroSupply | | Customer Reviews | 4.6 out of 5 stars 174 Reviews | | Item Form | Granules | | Item Weight | 5 pounds | | Manufacturer | EnviroSupply | | Manufacturer Part Number | coconut-shell-12x40-5lb | | Model Number | coconut-shell-12x40-5lb | | Target Species | Fish | ## Product Details - **Brand:** EnviroSupply - **Item Weight:** 5 Pounds - **Item Form:** Granules - **Manufacturer:** EnviroSupply ## Images ![12x40 Coconut Shell Activated Carbon | GAC Water Filter Media, 5 Pound Bag - Image 1](https://m.media-amazon.com/images/I/411SYfHOxbL.jpg) ![12x40 Coconut Shell Activated Carbon | GAC Water Filter Media, 5 Pound Bag - Image 2](https://m.media-amazon.com/images/I/81AKPQd8sUL.jpg) ![12x40 Coconut Shell Activated Carbon | GAC Water Filter Media, 5 Pound Bag - Image 3](https://m.media-amazon.com/images/I/71KKJhp-m3L.jpg) ![12x40 Coconut Shell Activated Carbon | GAC Water Filter Media, 5 Pound Bag - Image 4](https://m.media-amazon.com/images/I/817BAiIg0jL.jpg) ![12x40 Coconut Shell Activated Carbon | GAC Water Filter Media, 5 Pound Bag - Image 5](https://m.media-amazon.com/images/I/81YD9+z3ULL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What is the "fineness rating" so one can determine how powdery the product is ?

Improves taste, and removes volatile organics and chlorination byproducts that may come over condenser head with the distilled water. ### ⭐⭐⭐⭐ We use this in our Nutriteam Water Distiller *by S***G on February 2, 2018* We use this in our Nutriteam Water Distiller in place of the overpriced charcoal packets. I simply cut a cheap coffee filter down to size, wash a tablespoon (or less) of this charcoal in a strainer and place it into the distiller nozzle. Works perfectly for us and the water taste great. --- ## 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.us/products/46682255-12x40-coconut-shell-activated-carbon-gac-water-filter-media-5](https://www.desertcart.us/products/46682255-12x40-coconut-shell-activated-carbon-gac-water-filter-media-5) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-08*
