Including filter system and high-performance Tungsten filter.
Tungsten is a metal that occurs naturally and can end up in drinking water at low levels. It may be mobilized when groundwater moves through certain rock and soil types or where human activities affect local sources. Because tungsten is usually colorless and odorless, you won’t detect it without laboratory testing. Arran homeowners who want more assurance about their water quality often begin by checking for metals like tungsten as part of a broader water test.
As research into tungsten in drinking water continues, many people choose a cautious approach if testing shows elevated amounts. Clear-looking, normal-tasting water can still contain dissolved metals, so routine testing matters—especially for private well owners in and around Arran, where seasonal changes can affect water chemistry. If you’re on municipal supply, reviewing your utility’s water quality report and testing at the tap will confirm what’s actually entering your home.
To reduce tungsten at the main water entry, a whole-house reverse osmosis system is generally the most effective single-filter choice. RO systems force water through a semipermeable membrane that rejects many dissolved metals and inorganic contaminants, lowering tungsten before it reaches faucets, showers, and appliances in Arran homes. Simpler media focused on taste and odor won’t reliably stop dissolved tungsten, so a properly designed whole-house RO includes prefiltration to protect the membrane from sediment and any chlorine present.
A whole-house RO can be set up with storage and a delivery system to provide treated water throughout your home, but performance relies on correct sizing, sufficient pressure, and routine maintenance so the membrane continues to remove contaminants effectively. If your Arran property uses a well, additional pretreatment for hardness, iron, or particulates may be advised to extend membrane life. Mr. Pure Water can review your water test results and recommend a whole-house reverse osmosis system tailored to reduce tungsten for your household.
