Carbon Premium Catalytic

Sale price Price $34.99 Regular price


Kolar Labs Premium Catalytic Carbon quickly eliminates chlorine, chloramine and hydrogen sulfide from tap water, aquariums and reverse osmosis (RO) filtration systems. Our unique manufacturing process combines the best of adsorptive and catalytic carbons to also safely and efficiently remove unpleasant odors, tastes and other volatile organic compounds (VOCs) from your water.

Our laboratory-grade granular activated carbon features a large pore structure and high catalytic activity to remove a broad range of contaminants better than dechlorinators and other prime chemical removers. All Kolar Labs carbon is produced to rigorous food and drinking water standards for safe use across all applications.


  1. Eliminates chlorine, chloramine, hydrogen sulfide
  2. Removes organic contaminants, colors, odors, and volatile organic compounds (VOCs)
  3. Low dust and fines for quick rinsing
  4. For use in tap water filters, reverse osmosis systems and aquariums
  5. Highly effective in filter cartridges, filter bags and as a pre-filter in RO systems
  6. Manufactured to maximize absorption and catalytic removal performance
  7. Made according to Food Chemicals Codex (FCC) standards
  8. No harmful metals or alkalis often found in other catalytic carbons
  9. High purity, phosphate-free production process

Applications and Uses 

Kolar Labs premium catalytic carbon is made by Calgon Carbon specifically for chlorine, chloramine and hydrogen sulfide removal. It is a special catalytic activated carbon that quickly and effectively eliminates challenging contaminants in tap water that cannot be removed by standard activated carbons. Chloramine is growing in popularity as a disinfectant in many municipal water systems, and is not removed by traditional activated carbons or activated charcoals. Chloramine is extremely toxic to fish and aquatic life and it degrades reverse osmosis membranes resulting in decreased RO system performance and membrane lifetime.  

Our manufacturing process modifies the carbon’s surface electronic structure to create catalytic performance without harmful metals or alkalis used in other catalytic carbons. The production process is phosphate-free, to eliminate the potential for phosphate release from the carbon. The result is a fast-acting, laboratory grade carbon with high catalytic activity and low metal content that can be safely used in all applications, from tap water prefilters for RO systems to aquariums to remove chloramine and challenging organic contaminants such as volatile organic compounds (VOCs) and trihalomethanes (THMs).

Use Kolar Labs premium catalytic carbon to remove chlorine and chloramine to keep your RO system performing optimally. It is a high purity, food grade activated carbon that is safe for all freshwater and marine fish, invertebrates, plants, and pets.  

Detailed Instructions

How to Purify Your Water

Use in filter cartridges or filter bags; Short rinse before use; For use in tap water filters, pre-filters for reverse osmosis (RO) systems, and aquariums.

For use as a prefilter stage in an RO system, fill a filter cartridge tightly with carbon. Perform short rinse before use. Place catalytic carbon cartridge before the RO membrane stage to remove chloramine and keep your RO system running optimally.
