What the iSpring WGB32B whole-house removes
"Certified" means a certifier (NSF, WQA, IAPMO or CSA) lists this exact product for that reduction claim; the listing is linked. "Brand test only" means iSpring cites a lab report but no certifier lists the claim. See certified vs. tested.

What it costs to run
Yearly cost = replacements per year × filter price, for each filter it uses; a filter is replaced at its gallon rating or its month limit, whichever comes first. Water use: all indoor water (58.6 gallons per person a day).
