Q: How beneficial is a Brita water filter?

A: If you're fond of wasting money, go ahead… buy a Brita water filter.

Have you ever noticed that their ads only claim to reduce the "taste and odor" or chlorine? So all it's really doing is eliminating the warning signs that let you know this toxin is in the water - but you're still drinking it. And the same goes for fluoride. In fact, the company's website makes it quite clear that "you don't have to worry about missing out on the benefits of fluoride in your tap water."

I guess they think they're being reassuring. But when you know what I know about fluoride, it's anything but. Fluoride has been linked to immune system alteration, it may aggravate rheumatoid arthritis, and it may cause musculoskeletal damage, thyroid dysfunction, and even cancer.

The best way to guarantee you're getting safe, toxin-free water is to purchase a reverse osmosis filter and install it at your house.
