Water-Based Air Purifiers Challenge $100 Annual Filter Replacement Cycle
Source: Yanko Design
CUE's water filtration model eliminates disposable filters, competing on total cost of ownership rather than upfront price. Traditional air purifiers rely on replacement-filter revenue—a stream worth billions across 150+ million installed units globally. This inverts how appliance makers extract margin and forces established players like Dyson, Levoit, and Coway to defend a business model built on consumables. Consumer durability and sustainability concerns are creating viable alternative architectures, not remaining niche positions.
