Even spider plants don't like it.

A healthy spider plant has vigorous long, grassy leaves that are totally green or variegated. But all too often, the tips of these leaves are brown, which detracts from the overall beauty of the plant. The generally accepted theory about this browning is that it is caused by the presence of fluoride, sodium salts and/or chlorine in tap water. Most people don’t care — they just live with it.
