Okay, so you spent money on a filter. Great! Now don’t forget to change the cartridges. A clogged filter is like a clogged toilet—nobody wins. Set a reminder on your phone, or tape a note to your forehead. Whatever works.
Most systems need new filters every 6 to 12 months. If you ignore it, the arsenic might sneak back in and laugh at your efforts. Don’t let arsenic have the last laugh—be annoying and replace those parts.
