How Activated Carbon Filtration Works

Coconut Shell Activated Carbon Technology

Coconut Shell Activated Carbon Designed to Improve Water Taste and Odor

Where listed in the applicable Purewell product specification, the filtration media uses activated carbon derived from coconut shells. The coconut shells are processed to create a network of microscopic pores and a large internal surface area. As water moves through the media, certain compounds are attracted to and held on the carbon surface through a process known as adsorption.

Coconut Shell–Derived Activated Carbon Media Where activated carbon is listed in the product specification, Purewell uses activated carbon derived from coconut shells as part of the standard filter construction rather than offering it only as an optional upgrade.

How Activated Carbon Works

Coconut shells are converted into highly porous activated carbon. The media primarily works through adsorption, meaning certain compounds are attracted to the carbon surface instead of simply being screened out by pore size.

Water Enters the Carbon Media Source water flows around and between the activated carbon particles inside the filter.

Water Contacts the Porous Coconut Carbon Processing the coconut shell material creates microscopic pores and a large internal surface area for water and dissolved compounds to contact.

Certain Compounds Are Adsorbed Chlorine, taste-and-odor compounds, and certain organic substances may be attracted to and held on the carbon surface.

Water Continues Through the Filter After contacting the carbon media, water moves to the next filtration stage or exits the system, depending on the filter design.

Improves Taste and Odor Helps reduce compounds that can create unwanted tastes or odors in drinking water.

Helps Reduce Chlorine Activated carbon is commonly used to help reduce chlorine taste and odor in treated municipal water.

High Internal Surface Area A network of microscopic pores creates extensive contact area within a compact amount of filter media.

No Treatment Chemicals Added Activated carbon performs through surface adsorption and does not require chemicals to be added to the water.

Coconut Shell–Derived Media Uses activated carbon made from processed coconut shells, where specified for the applicable Purewell filter.

✓ Designed to Help Reduce

Chlorine taste and odor
Unpleasant tastes and smells
Certain volatile organic compounds
Certain adsorption-sensitive organic substances

i Understand the Filtration Limit

Does not normally reduce dissolved salts or TDS
Does not soften hard water by itself
Is not a complete microbiological barrier on its own
Does not reduce every contaminant without additional media

Important Use and Care Notes

Correct preparation and timely replacement help maintain adsorption performance and water quality.

Flush Before First Use Flush the filter according to the product instructions before drinking. This helps remove loose carbon fines and trapped air.

Temporary Carbon Fines May Appear A small amount of dark carbon dust may appear during initial rinsing. Continue flushing until the water runs clear.

Use Within the Recommended Temperature Range Do not use hot water unless the specific product instructions state that the filter is designed for hot-water use.

Use with an Appropriate Water Source Activated carbon alone does not make microbiologically unsafe, industrially polluted, or saltwater sources suitable for drinking.

Replace the Filter on Schedule Adsorption sites gradually become occupied. Replace the filter when its rated life is reached or when taste and odor reduction noticeably declines.

Follow Storage Instructions Clean and store the filter as directed when the system will not be used for an extended period. Do not leave stagnant water in the system longer than recommended.

Coconut Allergy Precaution This filtration media is derived from coconut shells. People with a known coconut allergy or sensitivity should review the product materials and consult a qualified healthcare professional before use.

Filtration performance depends on the activated carbon type, carbon quantity, contact time, water quality, flow rate, product design, and maintenance. Specific contaminant-reduction claims should be based on the applicable Purewell product specifications and test results.
