Around your home, furnace filters, water filters and water softener salt need refreshing at regular intervals. First, create a notebook just for home maintenance items in Evernote and assign a Post-it® Note color. Then, each time you change the filters, write down the product information on a Post-it® Note in that same color. Capture it with the Evernote camera in Post-it® Note mode. Your notes will automatically populate the notebook you created. Now, you can access it easily, and set a reminder for when it is time to change it.
