Coconut Carbon - Filtration From Nature

All of our water filtration products here at KOR, including KOR Plus, our new antioxidant and alkaline water bottle and filter use coconut carbon as the main media for making great tasting water. So why use coconut carbon vs. coal or wooden carbon as found in other filtered water products? 

Why use coconut shells?

Activated carbon is the filtering agent that eliminates contaminants from water. Carbon pulls unwanted particles, first, to its surface and then deep within its pores, leaving only the purest water possible.

Coconut shells are a renewable resource made of high-grade carbon and are ideal for filtration due to their high percentage of micro-pores on their surface, nearly 50 percent more than coal, making it the most promising option for removing a wide variety of particles and pollutants.

One of the guiding principles for all KOR products is the commitment to sustainability. So, when it came time to create our filtration products, we went with natural sustainable coconut shells.

Benefits of Coconut Carbon Filters

The key benefits of using coconut shell carbon for water filtration include:

  • Renewable source of carbon
  • Manufacturing is easy on the environment
  • Highly porous and tightly structured

The coconut shell filtration systems featured in KOR products have been custom developed to remove chlorine, chloramines (chlorine and ammonia) and objectionable tastes and odors found in tap water. It also reduces hydrogen sulfide and other organic contaminants. Because of coconut carbon’s wide surface area and its porosity, this form of filtration can remove chemicals that have proven difficult to expel using other forms of carbon.

Additionally, our coconut shell filters have independently undergone the NSF 42 test. This test establishes the minimum requirements of filtration systems to reduce aesthetic and non-health related contaminants like chlorine, taste, and odor from drinking water. The NSF 42 test analyzes the carbon filter for material safety, structural integrity and aesthetic, and claims about the reduction of non-health related contaminants. 

Coconut shells are a purer form of carbon compared to coal and wood filters. Other forms of activated carbon can add to an off-putting taste from inorganic ash, whereas coconut carbon is more tightly structured and won’t leach.

As previously mentioned, the fact that coconut shells are easy on the environment is hugely important to KOR. Coconuts will continue to grow without needing to cut down the tree itself (unlike when you use wood-based filters) and they’re harvested three to four times per year. Coconut shells can be easily preserved and manufacturing them as filters produces less carbon dust than their coal and wooden counterparts.

Hi Danielle Gaynor,

We do not currently have a filter recycling program but are working on it for the future. Keep in touch. Thank you!

are the casings for the filters recyclable? Do you take them back for recycling?

Many thanks,

Thanks for the comment, Marian. Water Fall’s filter has been custom developed by KOR to remove chlorine, chloramine (chlorine+ammonia) and objectionable tastes and odors found in tap water. It will also reduce hydrogen sulfide and other specific organic contaminants. Our internal tests have demonstrated a rating to 80 gallons meeting NSF 42 for chlorine and chloramine.

Nava’s filter is primarily designed to make tap water taste and smell great. It does this by reducing the amount of chlorine in the water. It has been tested by an independent lab to meet or exceed the NSF Standard 42, Class II for chlorine removal . The activated carbon in Nava’s filter also traps volatile organic compounds (VOCs) such as benzine, but the filter has not been tested or certified for this capability. It is also important to note that Nava is designed for use with potable water only. It does not remove Giardia or other harmful microbes.

Do you have a list of contaminants, Biological and chemical, that this device filters out? This site seems a little short on facts.
