A:Answer A lot of these product question requests I get are for the most part, common sense. To do masks, phones, eyeglasses, toothbrushes, etc, manual says to lay the mask/products out as flat as possible to ensure access to all surfaces, inner and outer. The reason being the infrared light needs to have access to ALL of them (surfaces). Anything exposed to germs, or the elements (not the inside of your phone).
Question- How can you possibly zap the insides of the tubes with something that helps you breath, and ensure absolute safety? Get a So-Clean from the William Shatner commercial. Better than chancing a respiratory infection.
This product works well but of course has its limits. It is not magic folks!
