“Pure vegetarian water? Must be an advertising gimmick!” the ad states. And then it gives reasons why it isn’t a gimmick. “Most purifiers claim to kill all viruses, bacteria and germs,” the ad reads. “But the chemically killed microorganisms remain in the water, making it safe, but effectively non-vegetarian.” Consuming dead creatures in your water, which they imply, is against the principles of vegetarianism. Seems like a somewhat sneaky way to play on peoples beliefs in order to make some sales.
