Grayl UltraPress Purifier Bottle
Preocupacion muy baja de PFAS
Veredicto: ComprarLower-concern design; no known PFAS-prone materials, but brand offers no explicit disclosure.
The Grayl UltraPress uses borosilicate glass and coconut-shell carbon for filtration, materials with lower inherent PFAS risk compared to Teflon-family coating membranes. The polypropylene housing and silicone seals are not inherently PFAS-heavy, though the brand provides no PFAS transparency statement or third-party testing.
Material: Borosilicate glass filter cartridge; coconut-shell activated carbon; polypropylene housing
