I am trying to love it

From what I can tell, the filter works really well. I am bummed with the size. With the pressure if the filter, the ounces of water you get is a lot less. I want to exchange this for a bigger size bottle but I am still waiting to hear back from Clearly Filtered. I hope they get back to me soon so I could say I love this product!

Never Going Back

The water from my Clearly Filtered filtered water bottle not only makes my tap water miraculously potable, but it also makes my water taste better than the plastic water bottles which my family buys. I can't drink out of anything else. I have recommended the Clearly Filtered water bottle to everyone I know. The only minor issue I have with this product is the difficulty I have screwing the lid on correctly. I also recommend offering a variety of colors for the rubber sleeves so that multiple people with the same product might easily differentiate their water bottle from mine or someone else's. Other than that, it's perfect and I love it. Thank you!

Haven't used it yet, but...

I actually haven't used it yet. I will mainly use it for traveling. I'm excited to have a product that filters out so many impurities and is lightweight and easy to use.

Frequently Asked Questions
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 220 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 99.5%. 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 >99.3%.
  • 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 >99.5%.
We are all about transparency so we post our full test results on our Test Results Page.
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.
