How does the UV water filter bottle work to purify water and make it safe for drinking?

The UV water filter bottle uses ultraviolet light to kill harmful bacteria and viruses in the water, making it safe to drink. When water passes through the bottle, the UV light disrupts the DNA of microorganisms, rendering them unable to reproduce and causing them to die off. This process effectively purifies the water and removes any potential contaminants, ensuring that it is safe for consumption.
