There are some UV products out there that do not have any kind of cover. Some of these dose surfaces at a less-powerful wavelength in order to be deemed “safe.” However, we’ve found that a more powerful dose ensures a high kill rate of germs which is why Vioguard has chosen to use ultraviolet light
within the optimal point of the germicidal range. There is a reason room cleaning robots and air purifiers require rooms to be void of any people while they are in use. To avoid that extra step of leaving the room, Vioguard products are created with lock-tight seals to prevent UV-C light exposure to end users. After all, your safety is the reason we make these products in the first place: THAT is our priority.
