Filter Keeper is an offline management tool for household consumable replacements. It is designed for water purifier cartridges, air purifier filters, air conditioner filters, pre-filters, and other common home filter supplies. You can create filter profiles for different rooms and devices, set installation dates, recommended replacement cycles, brand models, and spare quantities. The app automatically calculates days remaining and due status. Replacement logs, shopping lists, model notes, and local export help you avoid missed replacements, wrong purchases, and duplicate buying. No login is required. The app does not connect to the network or collect personal data. All records stay only on your device.
