Why do companies that supplies filtered water boast that it has UV protection?!
Answers: I don't understand why it's important to have UV protection for filtered water. Please explain.
UVA and UVB lite at high levels kill microbes that filtering can miss. Sort of like giving the little buggers a deadly sunburn. It wont change the taste the way chlorine will.
Marketing ploys to intensify the phobia fear in people who do not understand it makes no difference.
Ultra violet radition is harn full,hense it has tobe protected.
