The Kor Nava water bottle replacement filters 2-pack are made from pure coconut shells and are designed to remove chlorine taste and odor from water. The filters have been independently tested to exceed NSF 42 standards for chlorine taste and odor removal.
Nava’s filter is made from pure coconut shells. After harvesting, the shells are converted to activated carbon using a proprietary process that minimizes greenhouse gas emissions. Coconut shells are widely recognized as the most effective material for carbon filtration. Unlike coal from underground, which takes millions of years to form and may contain heavy metals, coconut shells are a renewable and health-safe resource. Nava’s filter has been independently tested to exceed NSF 42 standards for chlorine taste and odor removal.
