4 Lbs Bulk Water Filter-Air Filter Refill Coconut Shell Granular Activated Carbon Charcoal
4 Lbs Bulk Coconut Shell Granular Activated Carbon
NSF 42 certified 12x40 mesh GAC for refilling water and air filters. Acid-washed coconut shell carbon delivers superior chlorine removal, low dust, and extended service life in drinking water and food-grade applications.
Coconut shell carbon outperforms coal-based media
Coconut Shell Source
Made from selected coconut shell grades, not coal. Higher micropore density means better adsorption of chlorine, chloramines, and organic compounds in drinking water applications.
Acid Washed Process
Additional acid washing step removes impurities and reduces ash content. Results in cleaner carbon with minimal dust formation and longer filter life compared to standard GAC.
NSF 61 Certified
Tested and certified for drinking water contact. Safe for potable water filters, RO pre-filters, whole house systems, and any food-grade liquid phase application.
12x40 Mesh Size
Optimal granule size for most residential and light commercial filters. Balances contact time with flow rate. Low pressure drop while maintaining high adsorption capacity.
Dual Purpose Media
Works in both water and air filtration applications. Removes chlorine, taste, odor, and light organic chemicals. Superior hardness rating resists breakdown during backwashing.
Refill media for GAC filters and carbon tanks
This 4 lb bulk bag refills most 10-inch and 20-inch GAC cartridge housings, carbon tank vessels, and backwashing filters. Compatible with Pentek, Culligan, Aqua-Pure, GE, Whirlpool, and generic granular carbon filter shells. Also works in inline post-filters, countertop systems, and air purification canisters. One 4 lb bag typically refills two to three 10-inch standard filter housings. Rinse thoroughly before use to remove carbon fines.
Carbon replacement schedule by application
Drinking Water Filters
Replace GAC in cartridge housings every 6 to 12 months depending on chlorine levels and daily usage. Higher chlorine content shortens lifespan. Taste or odor return indicates exhausted carbon.
Whole House & Tank Systems
Refill backwashing carbon tanks and whole house GAC vessels every 12 to 24 months. Larger volume extends service life. Monitor pressure drop and effluent quality to determine replacement timing.
RO Pre-Filters
When used as pre-filter for reverse osmosis systems, replace every 3 to 6 months. Protects RO membrane from chlorine damage. Critical for maintaining membrane warranty and performance.
Air Filtration
For air purification and VOC removal, replace every 6 to 12 months depending on contaminant load. Activated carbon adsorbs odors, smoke, and chemical vapors until saturated.
High Purity
Acid washed coconut shell carbon with low ash and minimal extractables for clean, safe drinking water
Superior Hardness
Resists attrition and breakdown during backwashing cycles, extending media life in tank applications
Bulk Value
4 lb bag refills multiple filter housings at lower cost than pre-filled cartridges
Certified Safe
NSF 42 certified for drinking water contact and food-grade liquid applications (NSF certification under "Carbon Activated Corp")
