How it Works

Patented Technology

Protected by US Patent No. D906805 – as well as other utility patents pending in the US and worldwide.


The science behind UV water treatment is remarkably simple. When biological organisms such as viruses, bacteria, pathogens, etc., are exposed to UV light, the proteins present on the cell wall ruptures and causes the death of the microorganism. This effect is further enhanced when cells stop replicating as genetic material (RNA and DNA), and form thymine dimers upon absorption of UV light.

Solar Radiation

Sunlight consists of a wide range of electromagnetic radiation. Particularly, this radiation includes ultraviolet, visible, and infrared light. Ultraviolet is subcategorized into UVA, UVB, UVC regions. Of all the ultraviolet radiations emitted by the sun, only 3-4% reach the earth. Of the UV radiation that reaches the earth, 95% consists of UVA, 5% consists of UVB, and 0% consists of UVC due to the earth's atmosphere absorbing all the harmful radiation.

How UV-C Purification Works

Over the years, several scientific studies show the effectiveness of UV light in treating various surfaces. More recently, it has been found that UVC light has maximum germicidal efficacy, which means that by using an extremely low power of UVC light, one could treat a surface effectively. CrazyCap uses this special region of light to achieve its maximum germicidal effect. Using low powered UVC light offers great benefits in terms of safety and power consumption.
