Here's what actually removes PFAS from your water
The right filter eliminates PFAS at the tap. But not all filters do - and the type you choose matters for your home.
Common pitchers like Brita do not remove PFAS. You need a filter independently certified to NSF P473 (for pitcher filters) or NSF/ANSI 58 (for reverse osmosis systems). All three options below carry the relevant certification.

Frequently Asked Questions about ZIP 70084 Tap Water
What contaminants are above EPA limits in ZIP 70084?
ZIP 70084 has lithium above EPA health guidelines in the latest available data. The full table on this page lists every tested compound and its measured level.
Will boiling ZIP 70084 tap water remove lithium?
No. Boiling tap water does not remove lithium. Lithium is a dissolved mineral, so heat does not break it down and evaporation can actually concentrate it. Reverse osmosis (NSF/ANSI 58) is the most reliable at-home option for reducing lithium.
Do basic pitcher filters remove lithium?
Standard pitcher filters are not certified to reduce lithium. Reverse osmosis (NSF/ANSI 58) is the most widely available home option for reducing lithium in drinking water.
Who provides tap water in ZIP 70084?
Public records identify ST JOHN WATER DISTRICT 1 as a primary water system associated with ZIP 70084. Service boundaries can vary by address, so confirm exact service with the utility.
