PUR
PUR is a plastic system. Its faucet-mount units, pitchers, and dispensers are molded from BPA-free plastics (polypropylene and ABS), and on the faucet systems the entire housing the water passes through on its way out of the tap is plastic. The brand's pitch is contaminant reduction - lead, chlorine, and more - not getting plastic out of the water path, and there is no plastic-free way to own one. We list PUR as context, not as a plastic-free pick.
How clear are their specs?
PUR discloses its filtration certifications (WQA lead reduction, NSF/ANSI for chlorine and other contaminants) in detail and calls its plastics BPA-free, but it does not publish a full component-by-component material breakdown of the housing on its product pages.
