The Bottle

BPA/BPS Free

Our borosilicate glass bottle is 100% BPA and BPS free. It is infinitely reusable and won’t ever leach any harmful chemicals into your water. What’s more, it will never add plastic to our growing landfills, making it an environmentally friendly choice.

 

20-Ounce Capacity

Twenty ounces is a perfect amount for staying quenched during a workout or running errands around town.

 

Easy-Clean Mouthpiece

The hygienic flip-top mouthpiece makes for easy sipping and stores out of the way when not in use. It’s also a cinch to clean when the day is done.

The filter

Affinity Filtration Technology

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

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.

very good filter bottle

Experience and water quality is fine. Nice to travel with but for one exception. More protection would be good to add for breakage. One of the bottles was destroyed by dropping it in the airport and I feel if it had a few more heavy grade strips of silicone it still might be o9ik.

Great for travel and on the go!

Often, my main concern when I am out in public is having access to clean water. When I found out that there was a water bottle with the filter, I immediately bought it. Now, I feel confident that I can have access to clean water where ever I go.

Questions We Get Often
How long will the filter last?
The bottle filter lasts up to 25 gallons or 6 months (whichever comes first). This number may vary depending on how often it is used and the amount of contaminants in the water. Generally speaking, 25 gallons is about 160 fills in this bottle.
How do I clean the water bottle? Is it dishwasher safe?
The borosilicate glass water bottle can be cleaned in the dishwasher. However, the mouthpiece and straw need to be hand-washed in warm, soapy water. Never wash the filter.
What’s the bottle made of?
The glass bottle is made of a type of glass called borosilicate. It is specifically designed for thermal expansion so it will not crack during temperature changes.
Which contaminants does the water bottle remove? (e.g., Fluoride, Lead, Chlorine)
Our filtration technology removes over 230 contaminants. We use an independent, EPA-certified lab to rigorously test our filters to NSF standards. Here are just a few of the more notorious contaminants this filter removes:
  • Fluoride: removed at a rate of up to 99.9%. It is difficult to remove once it’s added into the tap water and typical carbon-block style filters don’t have fluoride removal capabilities. For that reason we specially formulated our technology so fluoride removal is standard with every filter.
  • Glyphosate: The active ingredient in Roundup® weed killer. Our filters remove 99.9% of this highly controversial chemical.
  • Lead: Even though it’s been widely banned due to its highly poisonous nature, lead pipes remain in use across all 50 states. Lead is harmful to human health even at low exposure levels and accumulates in the body over time. Removed at a rate of 99.9%.
  • Chlorine: While chlorine is effective at reducing the spread of infectious waterborne diseases, it reacts with naturally-occurring materials in water to form dangerous chemical byproducts that threaten your health. Removed at a rate of 99.9%.
We are all about transparency so we post our full test results on our Test Results Page. It shows the name of the particular contaminant, the concentration before filtration, the concentration after filtration, and the percentage removed.
Is it hard to drink water through the straw?
The filter contains a dense block of filtration material. As you draw water up through the straw the filter will cause some restriction in the flow of water, but it should feel similar to drinking a thick milkshake.
