filter
The cartridge format is the operational difference from AquaSana's tank: easier to swap, smaller utility-closet footprint. SpringWell's brand-level certifications are real (IAPMO at the corporate level) but they aren't surfaced in the Amazon listing the way AquaSana's are. We include SpringWell as the catalog alternative; AquaSana remains our pick on cert-surface clarity.
