Water Purification + Self-Cleaning
Purified Water in 60 Seconds

This revolutionary new water bottle purifier is built-in with a deep UV LED sterilization technology in the cap. Instead of trapping micro-organisms like traditional filters, the deep UV light destroys them completely.

Put an End to Moldy Smelling Bottles.
Auto-sterilization works every four hours and prevents the growth of mold in the bottle. As a result, our bottles never smell moldy.

Works on Various Surfaces

Sterilize any surface by shining CrazyCap from two inches away to achieve sterilization up to 99.6%. Treatment time: 30 sq. Inch per minute.
