Thou shalt not drink bottled water. (An eco-mmandment we hear often.)

Thou shalt not deny the convenience of portable drinking water either! (We hear this one in our head.)

But with 38 billion plastic water bottles in landfills each year, it’s a habit in need of kicking.

First, know your local water. Every year by July 1, your water supplier should make available an annual water quality report.

Don’t like what you read? Give your water a rinse with a commercial system (Brita-type pitchers, faucet mounted filters). Most rely on carbon to filter out impurities (unwanted tastes, smells and chemicals)—it’s also extremely cost effective.

For an earthier method, use iodine drops—5 drops per quart will generally do the trick. Wait 30 minutes before drinking to be sure the water is purified.

Now all you need is a stylish, safe, reusable bottle for your home-filtered water. With Klean Kanteen’s stainless steel model or SIGG’s super-chic designs, you’ll be sipping pretty in no time.
