Trust Hammacher to be able to lay claim to carrying the “only stainless steel water bottle with an integrated filter”. But that’s exactly what this is and me likey. The filter can get clean 100 gallons of H20 before needing to be replaced and removes up to 99.99% of microbes, which exceeds or meets EPS water filtration standards.
Would you trust it to filter water from a random stream you happen stumble upon while hiking? You would if you were lost and thirsty. $50.
