HM FM-1  Filter Monitor is an innovative system to alert when a filter needs to be changed via color-coded lights at the base of the faucet.

FEATURES

A five-stage filter monitor with five independent timers and a tri-color LED faucet indicator disc.
Works on time (and volume for the FM-2) for up to five stages (can be less).
The LED indicator disc will illuminate a green, yellow or red light when the water is turned on.  The color indicates the percentage of elapsed time.
Auto-Off function conserves battery power. The unit shuts off automatically after 5 minutes of non-use.
The timer counts down in months or days (settings can be modified).
Includes an audible alarm (beep).
Modern design is perfect for any kitchen.
Installs quickly and easily.
