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.
Provide your family with easy access to pure, clean, wholesome water that’s better than bottled, everyday...right at home.
