Can I use SteriPEN on water with ice in it?
No, we do not recommend you use the SteriPEN on water with ice in it because the UV light cannot pass through the air bubbles or impurities in the ice. We recommend removing the ice from the drink before treating it. You could also allow the ice to melt and then treat the water.
