Email Reminders automatically send you an email when it is time to replace your filter cartridges. Please select a starting date and replacement frequency, and then enter your email address. If you have both drinking water and shower filters and their replacement frequency differs, you will just need to click the products you own. (If the replacement frequency is the same for both filters, signing up for two email reminders is unnecessary.)
To see how often you should replace your filter cartridge, please refer to the replacement frequency chart.
