Does the SteriPEN take care of the water droplets on the threads of my water bottle?
SteriPEN does not purify the threads of a water bottle. Users should use their finger or a piece of cloth such as a bandana to wipe off the threads of a bottle before drinking. Another way to address this issue is to use our Pre-Filter. Our Pre-Filter attaches to the opening of a standard wide moth Nalgene type bottle. The Pre-Filter is designed to keep the threads dry while submerging the bottle into your water supply. You can see the Pre-Filter on our products page.
