The Best Water Purifiers for Fresh and Clean Water

The best water purifiers can provide great-tasting water that may be safer to drink than your tap water. With them, you can worry less about harmful contaminants.

Depending on where you live, tap water can contain contaminants such as rust, chlorine, fluoride, and lead, or even bacteria or viruses. Fortunately, the best water purifiers offer a great solution for making your water taste great and removing harmful bacteria and contaminants. Though single-use plastic water bottles are sometimes used to drink better-tasting water that has already been purified, most water filters on the market can replace hundreds of plastic bottles at a fraction of the cost and simultaneously reduce the impact on the environment. Whether you’re an outdoor enthusiast or a homeowner, if you’re looking for better and safer water, a water purifier can be useful. From built-in water filtration systems to portable water purifiers, there are a variety of useful water purifiers available to provide you with clean, great-tasting water to drink any time. The best water purifiers are effective and are sized to fit your needs and the situation you need them in.

Bob Vila

Media Mentions from Bob Vila

You probably know Bob Vila from TV, where for nearly 30 years he hosted a variety of shows: This Old House, Bob Vila’s Home Again, Bob Vila, and Restore America with Bob Vila. Or perhaps you caught Bob starring as himself on Tim Allen’s sit com, Home Improvement. You can now watch Bob's full TV episodes online.

Before his life in broadcasting, Bob launched his own residential remodeling and design business. Earlier still, he served as a Peace Corps volunteer, building houses and communities in Panama. He learned first-hand about home building from his father, who hand built their family home. He's written 12 books about remodeling your home, buying your dream home, and visiting historic homes across America. It’s fair to say that buildings, especially homes, are his life’s work.

Now he's breaking new ground on the web, at BobVila.com.

My only complaint is that eventually, backflushing won’t be enough. These can clog up after some time and no amount of back flushing will fix its low flow. I went through 2 on the AT. However, it will attach to Smart Water Bottles and most bladders!

Built for backcountry reliability and portability, the Sawyer Squeeze filter is our pick for the best portable water purifier.

MEDIA MENTIONS

The Sawyer Squeeze was (by far) the most common Pacific Crest Trail water filter this year – for the fifth year in a row. It’s a $39, 3 oz / 85 g hollow fiber filter that rids your drinking water of protozoa and bacteria (and floaties). It can be used with Sawyer bags (included with the filter) or with compatible water bottles (Smartwater is the bottle of choice for many hikers).
