Water filters

Water filters selected for what they actually reduce, with particular attention to microplastics, lead and other drinking-water contaminants.

Start with your water report, then choose a filter tested for the contaminants you want to reduce.  We prioritize verified microplastic reduction and check the exact system and replacement cartridge behind each claim.  Plastic housings, tanks and tubing are allowed here and disclosed.  A taste-improving charcoal stick is not a substitute for a complete filtration system; replacement schedules matter too.
