Whole-house scale without salt. Does not remove arsenic, nitrate, or fluoride.
Electronic descaler, not a softener and not a conditioner with media: two coils wrap the main line and induce an electromagnetic field. Manufacturer positions it for 10-19 gpg water and says over 25 gpg needs a traditional softener, and iron over 0.3 ppm needs an iron filter first, so it is a city-water (10-12 gpg) gadget at best; not recommended as the primary treatment for 15-20 gpg well water.
Clearly labeled: electronic descaler with NO independent certification. iSpring states 'The ED2000 is NOT a water softener and does not REMOVE calcium or magnesium'; not certified to NSF/ANSI 44 and no IAPMO/DVGW scale-prevention test is cited (scale-reduction claims are manufacturer-only and the effectiveness of electronic descalers is not established by third-party standards). Salt-free conditioners/descalers do not remove hardness minerals. Manufacturer: works on any pipe up to 1 in.
