Not suitable for
- Treating every tap in the home
- A whole-home hard-water or scale problem
- All PFAS: its evidence covers only the compounds it names
- Anyone who can't plumb, drill or hire an installer
Test first
- Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
- A tap test can confirm levels at your home before you choose treatment.
