It’s not in the water: product review of water purifiers GRAYL Ultra Light VS SteriPEN Ultra and Lifestraw Go 2

I currently live by one of the Great Lakes and access to clean drinking water here is typically not a problem. However, when planning a trip abroad, or even a long hiking adventure, you have to think about your access to clean drinking water. There are many options out there, and it is best to find the right option for our needs. When I planned on being in India for a month, I researched the best options for my travels. Of my research, my top three choices for  water purifiers are GRAYL, SteriPEN Ultra, and Lifestraw Go 2

LifeStraw Go 2

LifesStraw has been around since 1994 with its first product the original straw developed in 1999. Since then, they continue to create new products.
The LifeStraw Go 2 incorporates a carbon capsule into its existing award winning technology.


  • Uses a replaceable carbon capsule which is good for 100 liters (26 gallons). This equals to about three months of consistent use.
  • Removes 99.999% of water borne Protozoa and bacteria including E.Coli
  • Fill up the water bottle from any source and the straw does the filtration


  • Does not protect against viruses. It is important to check where you are traveling as you may need protection from viruses too
  • Need to sip/ suck the straw for water. You cannot get a “gulp” of water.
  • Cannot use the bottle to fill up other bottles/ bladders

NOTES: Replacement filters cost around $10.00 USD for a two pack

SteriPEN Ultra


SteriPEN got its start in 1999 and in 2011 Time Magazine In its “Top 100 All Time
Gadgets”. Unlike other SteriPENS, the SteriPEN Ultra is rechargeable.
  • Quick and easy to use
  • Emits UV rays that destroys bacteria, Protozoa, and viruses
  • The Ultra is good for 8,000 uses


  • Does not remove sediment, and not good for murky water
  • Breakable -especially if you drop it without its protective case
  • Your need to have access to a power source to recharge the  
    battery- may not be the best choice for remote travel.

GRAYL Is the new kid on the block. The company was founded in 2012. Thier first product, The Water Filtration Cup, quickly received a lot of media attention. The latest product, the Ultralight, boasts a one press technology for clean and safe drinking water.

  • Quick and easy to use- less than 30 seconds to 16 oz of clean water
  • 99.999% protection from bacteria, Protozoa, and Viruses
  • No batteries, chemicals or UV lights
  • Can fill up other water bottles/ bladders


  • Can be difficult to press. Be sure to have leverage and do not seal the top completely
  • The price of the bottle is higher than LifeStraw, and the filters are pricier

NOTES: The cost of the orange filter is around $24.95 USD and the two pack blue tap water filters is about $22.95 USD

    I think this is a great product and will help so much when people go to places where clean drinking water isn’t available. As you said in your post, these bottles cartridges filter up to 100 litres of water, which I think is really good.

    This is definitely a product I would be interested in.
    Thanks for sharing.

      Hello Steven!  

      I used the GRAYAL bottle in India and it was fantastic. I never had to worry about access to clean water, and I felt as I was not contributing to the excessive plastic waste.  Let me know if you get a GRAYAL or another purifier. I’d love to hear your experience.
