What is Cartridge price?

A cartridge price is what you pay for one replacement filter, in a water filter or an air purifier. It is a single purchase rather than a monthly subscription, and it sets the running cost of the machine once the original filter is used up. Each figure here comes from the brand's own shop or pricing page, in its local currency. Alb Filter charges €25.90, Acala charges €44.90, aigerri charges $89.98, Airthereal charges €43.95, and AirWin Group prices its cartridge at €69.99 to €99.99.
