There are several options for treating your own drinking water when you travel.

TAP Liberty Bottle No matter which you choose, you will want to carry 1-2 reusable water bottles. We recommend Liberty Bottleworks, Liberty bottles are the ONLY bottle to be made from recycled materials and are manufactured right here in the USA. We recently designed our own Liberty bottle that will be available for purchase soon. 

$5 goes to help support TAP's mission: GET A TAP Bottle



The SteriPEN is our top time-tested method for treating drinking water when traveling. The SteriPEN utilizes the power of ultraviolet light to eliminate over 99.9% of bacteria, viruses and protozoa that cause water-borne illness. Models like the SteriPEN Freedom are great for travelers because they are compact and can charge via a USB port. The wide mouth on the TAP Klean Kanteen is compatible with SteriPEN use; simply dip and stir until the light turns green. TAP is now an authorized dealer of Steripens and the profits from your purchase go back to the charitable work of the TAP Campaign and sustainable travel education. You will receive a tax-deductible receipt for each purchase.

Water purification tablets are an old standby that work well and are affordable. For about 8 bucks you get a bottle of 50 tablets, which you use two at a time to clean 1 liter of water. It does the job. The only drawback is you need to wait about 30 minutes for the tablets to dissolve, and the taste can be a bit bad which is why you should always get the little yellow bottle of neutralizing tablets as well. It is simply vitamin C but it removes any lingering taste.




Water filters and purifiers are another option, especially if you are spending time in the backcountry and pulling water from streams and lakes. Both filters and purifiers remove protozoa and bacteria from water, but only purifiers also remove viruses. REI has several different filter and purifier options (, and you can speak with well-informed staff at their stores to assess your specific needs. We’ve used the First Need Water Purifier for many years and find it to be easy to use and effective.
