Deceptive snake oil.
If you read the instructions for another GermGuardian product, their mini wand, you will note they say the light must be in contact for 20 seconds to disinfect. With this GG1000, there is no way the air is staying in contact that long. At best, it's likely a second or two by time the air passes through. Also, look at the internal area. It's only cubic inches. A typical 10 x 12 room is 1,000 cubic feet. There is no way the air in your room is being circulated into this device at any noteworthy level. Put a piece of paper up to the air input on the device. Notice it doesn't suck it in much? How is it going to suck in some mold spore or bacteria on the other side of the room? Now, you could get lucky if you have a fan or air conditioning moving air around in the room. But still, this device doesn't have much power to suck in air. Anything that gets into the devicemust be within inches of it, and pure happenstance. I doubt once it's inside it is there long enough to be sanitized.... In theory, this device could work. But you would need it to be 1/3rd the size of your room.
