The UV toothbrush holder and sanitizer is a great way to limit the amount of “germs” on a toothbrush. The appliance uses ultra-violet rays to zap away bacteria, fungi, and viruses. Toothbrushes that are contaminated with germs can cause health issues from a common cold to disease transmission. Germs love damp environments, and with toothbrushes, they are almost always damp from morning and evening use. The UV toothbrush sanitizer is also a bonus for children who seem more susceptible to becoming ill from germs. This appliance takes two AA batteries and retails for under $40.
