Keep your reusable bottle as clean as possible with the CrazyCap Portable Bottle Sterilizer. Replacing the cap on cola-style bottles such as MIRA and S’well, this clever device automatically cleans the water in your bottle when it’s screwed on. It uses the power of LG UVC light ray technology to zap microbes. Totally free of chemicals, it destroys 99.999% of mold, bacteria, and viruses. Because these reusable bottles are often so hard to clean, they can quickly fill with germs even when washed regularly. The CrazyCap reaches every nook and cranny of the bottle, leaving you with exceptionally clean water. Tap CrazyCap twice, and it cleans your water in 60 seconds. When pressed five times, it purifies in two minutes for water from a lake, pond, or other questionable sources. CrazyCap also automatically cleans six times a day in 20-second intervals to ensure you’re only drinking the best water.
