LifeStraw
Specs partially disclosed lifestraw.com ↗
A filtration brand first, with the Home glass pitcher its most plastic-conscious product rather than a company-wide ethic. Filtered water does sit in hand-blown borosilicate glass on a silicone base, which is the good part — but the water reaches that glass by passing through a plastic filter housing, and the lid is plastic too. So it minimizes plastic on the storage surface while keeping it in the flow path, which is inherent to a membrane microfilter.
How clear are their specs?
The glass and silicone parts are clearly described, but the plastic filter housing and lid are acknowledged more than characterized, and the broader (largely plastic) product line sits behind the Home line's glass showpiece.
