Questions

Is UV light harmful to humans?
Short term exposures of UV light can cause burns. Short term direct exposures to the UV LED lights can cause permanent eye damage. The hazard is comparable to that associated with ultraviolet curing of dental filling restorations. A set of laser safety glasses (that look like rose-colored sunglasses) meant to protect against 190-540 nm light is sold with each of our products. To test the sunglasses out, one can briefly test out the laser safety glasses by seeing the red light at a stop light, but not the green or yellow.
How does UV light sanitize surfaces, air, and water?
Each UV wavelength has been selected to disrupt protein function by a different mechanism. The set of wavelengths has been chosen to be effective against all pathogens, not just COVID-19.
How often do I need to change the lights on my device?

When each product is powered via conventional AC power, an audible and/or visible alert will tell the user if the product is not functioning. During the event of an unexpected power outage (as opposed to the user turning the power off), a different type of audible and/or visible alert will alert the user that the product is functioning on backup battery power; when such backup battery power is exhausted, the alert will cease. If normal power is restored, the alert signaling the user that the product is using backup battery power will cease.

Can I use my CFS device outside?

If portable, your CFS device can be used outside. 

How often should my CFS product be cleaned?

If not permanently mounted, our CFS product should be disinfected using a sterilizer box. Such a sterilizer is available as an accessory. If permanently mounted, our CFS product is designed to be self-cleaning on a periodic basis. 

Can bacteria resist UV light?

Each UV wavelength has been selected to disrupt protein function by a different mechanism. The set of wavelengths has been chosen to be effective against all pathogens.

What is an HAI?

An HAI is a hospital-acquired infection.
