Why do I get zapped everytime I touch the doorknob?
The device does spray a form of electricity into the air, which can cause your body to “charge up” with static electricity. If you have the ionizer running in a small enclosed room, the effect may be even more pronounced. Although this can lead to the possibility of you getting zapped every time you touch a doorknob or other metal object, it is completetly harmless and is no different than shuffling your shoes across the carpet.
