Who should buy which
City-water homes that want softer, chlorine-reduced water at every tap without the salt hauling, brine refills, or water waste of a traditional ion-exchange softener.
You have well water with iron or hydrogen sulfide, or you need true scale removal and measurable grain-capacity softening, which salt-free conditioning does not provide.
Emergency preparedness, off-grid living, and travel where grid water cannot be trusted and you need true virus-level purification, not just bacteria filtration.
You need a continuous high-flow household supply, an NSF/ANSI-numbered certification on paper, or an ultralight backpacking filter (the Sagan XStream straw is the lighter pick there).
