Including filter system and high-performance Tungsten filter.
Tungsten is a naturally occurring metal that can end up in drinking water at low concentrations. In some places, groundwater interacting with particular rock and soil types—or nearby industrial influences—can raise levels, and because tungsten is usually colorless and odorless you won’t detect it without laboratory testing. Delta homeowners who want greater peace of mind often start by checking for metals of concern, tungsten among them, so they know what’s in their water and whether further action is needed.
While research into tungsten in drinking water is still developing, many Delta residents take a practical, precautionary stance when tests show elevated amounts. Clear, good-tasting water can still contain dissolved metals, so routine testing is a sensible step—especially for private wells, where seasonal shifts and usage can change water chemistry. If you’re on a municipal supply, reviewing your water quality report and testing at the tap can confirm what’s entering your home and whether treatment is warranted.
To lower tungsten at the point of entry, a whole-house reverse osmosis system is generally the most effective single-filter option. Reverse osmosis forces water through a semipermeable membrane that rejects many dissolved metals and inorganic contaminants, reducing tungsten before it reaches Delta faucets, showers, and appliances. Because tungsten exists as dissolved species, it can pass through simpler media designed for taste or odor; a properly engineered whole-house RO includes prefiltration to protect the membrane from sediment and chlorine where relevant.
A whole-house reverse osmosis system can be set up with storage and delivery to provide consistent treated water to every fixture in your Delta home. Reliable performance depends on correct system sizing, sufficient water pressure, and regular replacement of filters and the membrane to prevent fouling. Homes on wells may need extra pretreatment for hardness, iron, or particulates to preserve membrane life. Mr. Pure Water can review your water test and recommend a whole-house RO configuration built to address tungsten effectively.
