Hello clean water enthusiast! Hydro Flask has redesigned their bottles for 2020 increasing the height. If you have purchased your Hydro Flask after February 1st 2020 please reach out and we will send you the exact length for your bottle! This will help us minimize plastic waste that you may not need!


THE ANSWER is a simple, but revolutionary solution for contemporary water bottles. Keep your favorite Hydro Flask, Nalgene, Camelbak TruFlask, or Hydro Cell wide mouth bottle. Ditch 99.99% of the harmful tap water contaminants inside of it.

We all love our double-insulated, wide mouth Hydro Flask bottles, but the fact that they don't include a filter, left us without an answer. That is, until we decided to create one.
