Loved by Our Early Sippers
"You don't really know what you're drinking all the time. Having [the CLEANR SIP] is a good reassurance. I really like how you don't have to buy a new water bottle... you can just add it on."
Marcus T
Tested with Hydroflask
"It's fresher, it's better than tap water. I personally don't like drinking tap water, but the filter makes it better"
Dana R
Tested with Hydroflask
"I like that it goes into different types of water bottles. I already have 50 bottles, so if I grab one, it's good to know it will fit."
