Proprietary consumables—filters, bags, cartridges, and pods—transform static assets into recurring revenue streams for the manufacturer. This is the Razor and Blades business model applied to the modern home.
The base unit cost of an air purifier is frequently subsidized. Over a 5-year operating window, the requirement for proprietary HEPA and activated carbon filter replacements typically exceeds the initial purchase price by a factor of 1.5x to 2x.
Single-use pod coffee systems and refrigerator water filters present egregious markups. Refrigerator water filters can command $50+ per unit for basic carbon blocks, mandated for replacement every 6 months to bypass artificial software locks in smart appliances.
