Best Plastic-Free Water Filters
Pitchers, gravity dispensers, and countertop/under-sink systems for filtering drinking water.
Why plastic matters here
The central irony of the category: people filter their water to remove microplastics and contaminants... through an all-plastic Brita pitcher into a plastic reservoir. Glass-carafe pitchers and stainless gravity systems (Berkey-style) exist but are a minority, and filter cartridges themselves always have plastic housings - so the honest framing is minimizing dwell time in plastic, rarely eliminating it.
What to look for
- Where does the filtered water SIT? The reservoir material matters more than the funnel
- Filter cartridge housings are plastic in essentially every system - a fair minimal-contact concession
- Stainless gravity dispensers hold the largest volume plastic-free
- Does the filter actually remove microplastics/PFAS? (certifications: NSF/ANSI 401, 53)
Our picks
The honest answer to the category's central irony: filtered water sits in and pours from stainless steel, not plastic. Both chambers are 304 steel and the spigot is stainless with a ceramic valve, so the only plastic is the unavoidable filter-housing hardware. Certified to NSF/ANSI 401 for microplastics and 53 for lead/PFAS, and it holds the most filtered water plastic-free of anything here.
A near-identical stainless gravity dispenser (formerly Propur) with the same NSF/ANSI 401/53 microplastics-and-lead certifications and steel chambers. The one asterisk versus the Boroux: base configurations ship a plastic spigot, so buy the stainless spigot upgrade if you want the dispense path fully metal.
The fridge-friendly pick. It swaps the all-plastic Brita tank for a hand-blown borosilicate glass reservoir on a silicone base, so filtered water dwells in glass. The filter housing and lid are still plastic in the pour path (why it's minimal-contact, not no-contact), but its 0.2-micron membrane is specifically certified to exceed NSF/ANSI 401 for microplastics - a big step up from a standard plastic pitcher.
Considered, but not picked
Popular options that look plastic-free but aren't — and why.
Brita pitchers (Standard / Elite)
The exact thing this category is a reaction to: filtered water sits in a polypropylene/SAN plastic reservoir. Only the Elite filter carries NSF/ANSI 401 for microplastics at all - the standard filter isn't certified for them - and even the Elite deposits its output straight back into a plastic tank, undercutting the point of filtering for microplastics in the first place.
