Affinity® Filtration Technology
Click Here for the Lab Report
The filter in our water bottle is powered by the same Affinity® Filtration Technology as our water pitcher filter, under-the-sink filter, and refrigerator filter, providing superior contaminant removal on the go.
Removes 220+ Contaminants
Our bottle filter, powered by Affinity® Filtration Technology, removes 99.9% of fluoride, lead, mercury, microplastics, BPA, glyphosate, pesticides, and a total of 220+ potential tap water contaminants.
25-Gallon Filter Life
For example, with a 25-gallon filter life, the Clearly Filtered® 20-Ounce Borosilicate Glass Water Bottle provides clean and safe drinking water for 160 fill-ups. This means if you fill up twice a day, you’ll need to replace your filter about every 2-3 months. Only fill up once a day? Replace every 4-5 months.
Published Performance Data
We believe in radical transparency, so we freely publish the results of our independent laboratory testing for your review. We think you’ll find it pretty refreshing.
