ZeroWater
ZeroWater is a plastic system. Its pitchers, reservoir trays, and lids are molded from BPA-free polypropylene and ABS, so filtered water pours through plastic and then sits in a plastic tank until you drink it. The brand's strength is filtration performance - a 5-stage filter independently certified to reduce PFAS, lead, chromium, and virtually all TDS - not the material of the vessel. There is no plastic-free way to own one; we list it as context.
How clear are their specs?
ZeroWater publishes its filtration certifications (IAPMO/NSF-equivalent for lead, chromium, and PFOA/PFOS) and states its pitchers are BPA-free, but it describes the housing plastics only in general terms rather than a full per-part material breakdown.
