Thankfully though, the powers of UV lights were finally incorporated in water bottle designs. The latest in modern innovations today that you need to experience is the self-cleaning water bottle.

Buyers Guide

You also need to know the length of time it takes for the bottle to sterilize. Good ones already include an automatic cleaning function. You also need to consider the capacity of the water bottle—this will depend on the amount of H2O you drink every day. Check the design and see if it will fit inside bags/backpacks that you use daily. See if it comes with insulation functions as well. Evaluate the battery life of the device—check the length of time that the bottle lasts on a complete charge and the number of cleaning cycles it carries out.
