Our Water Filter Bottle Buying Guide

Water filters have been around for decades, with versions you attach on faucet ends and in water pitchers. Now, today’s water filter bottles are hi-tech, portable and convenient. Some remove almost 100% of the chemicals and other unwanted particles that occur naturally in water, and they are safe enough to use with untested sources like freshwater lakes.

These bottles are made from glass, stainless steel, aluminum or plastic (look for BPA-free plastic), and they can have either small or wide-mouth spouts or straws. They are not always inexpensive, but purchasing one bottle of this kind, rather than buying single-use, plastic water bottles, can save both money and the planet.

The filters in these containers tend to last a long time, but before you buy the bottle, find out how new ones can be purchased (and what their price is).

You may want a smaller, 16-ounce bottle, or a larger one for long treks. Some hold 48 ounces or more, but these will be quite heavy. Sizable drinking containers are great for long car trips and camping. They are also handy to keep by your desk while you are working.

Simplemost Fun Fact

It is widely believed that Perrier was the first bottled water sold, but the history of the product goes back much farther.

Back in 1622, the United Kingdom’s Holy Well bottling plant sold water, though by the name, it may sound like more of a gimmick than anything else.

Still, natural springs have historically been associated with therapeutic and healing effects. When Perrier was introduced in the late 1970s, it was branded as “Earth’s First Soft Drink.”

The Water Filter Bottle Tips and Advice

  • Not all water filter bottles are dishwasher-safe. If they are, they will have specific washing instructions. If you do not follow them, your bottle may get damaged or ruined.
  • Some filters last longer than others, so read the product descriptions carefully and change filters according to the recommendations.
  • These bottles make especially great gifts for friends and family members who travel, cycle or hike.
