Why is the printer-and-ink model a concern when purchasing an air purifier?
Answer
It locks consumers into purchasing expensive, proprietary replacement filters
The printer-and-ink model describes a business strategy where the initial air purifier unit is sold at a low, attractive price, but the user is later forced to buy proprietary replacement filters that are significantly overpriced. Over several years, the cost of these mandatory filter replacements can far exceed the initial purchase price of the machine. It is critical for consumers to research the ongoing cost and availability of compatible or generic filters before committing to a specific model.
