> not to mention all of the other organic certifications have different definitions of 'organic'. It can be 100% organic and still sprayed with pesticides etc. >Do you have any filter recommendations? A three stage filtration system is ideal, I have the Whirlpool WHAMBS5 but any will probably suffice. But just be aware that that still doesn't make a huge difference, you will probably never fully be able to escape fluoridation etc. Because it's in all of your drinks including milk, all teas naturally contain fluoride, your food esp vegetables and fruits, when you take a shower you're inhaling large quantities, canned food especially has fluoride in it. It's just kind of stupid trying to avoid it entirely honestly and it's naturally occurring anyways. Our ancestors all drank and ate fluoridated products and water, often probably far exceeding doses today. One woman developed skeletal fluorosis from drinking tons of well water mixed with powdered tea, both containing high amounts of fluoride completely naturally. It's also a big issue in Africa. I think our levels probably aren't particularly egregious.
