Safety First; Warnings & Cautions - Philips GoZero Manual

3. While using the bottle in the backcountry or during travels,
we recommend to run the puri cation cycle twice to ensure
the safety of the water. It's also advised to take additional
precautionary methods depending on the water source
quality, since the bottle doesn't filter out contaminants
such as particulates, chemicals or heavy metals.
Notes:
- Do not interrupt the purification cycle by removing the cap
or pressing the button.
- This product is not intended to purify liquids other than water.

Safety first

NEVER activate the UV-C function when the cap is taken
outside the bottle. If it's activated accidentally, the indicator
light will flash orange for 5 seconds to remind you, and the
UV-C function will be off automatically.
If the liquid is too hot (above 60℃/140℉) or too cold
( below 4℃/39.2℉) inside the bottle, the safety protection
mode will be on automatically to protect the UV-C module,
and the indicator light will flash orange for 10 seconds.
