Water is crucial to keeping you hydrated when outdoors especially when taking part in strenuous activities such as hiking, cycling, backpacking, running, camping, and the list goes on. But instead of carrying around a large water reservoir system that can add extra weight and strain, you can opt for a water bottle purification or filtration system. This will help keep your carrying weight to a minimum, keep you hydrated, and also give you the peace of mind that your water is clean and free of harmful particles. You can also have an endless supply of water as long as you are near freshwater source such as a river, lake,  or creek.

There are different kinds of water purification and filtration systems out there and many factors to be considered when deciding which one is right for you.  There are a few key things to know when making your decision.


Filters and purifiers are different:

Filters use a mechanical system to push water through a filter where they remove bacteria (E. Coli, dysentery, etc.) and Protozoa (Giardia, Cryptosporidium, etc.). However, Viruses (Hepatitis A, Rotovirus, etc.) are typically not filtered out on most filters. For filters: Look for the “absolute pore size”. You want an absolute pore size of 0.2 microns or less, as 0.2 microns is the smallest size of bacteria.

Purifiers use UV light to treat protozoa, bacteria, and viruses but do not filter out any sediment suspended in the water. Because Purifiers do not strain out any sediment, the taste of the water will not be enhanced.

 This past weekend, the staff here at Park Visitor headed down to the Anaheim Convention Center where the Natural Products Expo was taking place. We searched every floor, booth, and table looking for the best hydration products for the outdoors. At the end of the day, we narrowed it down to our top 5 water bottle filtration systems that will keep you going strong and healthy wherever you are.

Park Visitor’s Picks

Clearly Filtered – Insulated Stainless Filter Bottle (Filter) – Park Visitor was attracted to this filter-water bottle combo because Revolve (the company that makes the filters) claims to remove 99.99% of viruses and not just the bacteria and protozoa that other filters eliminate.

Clearly Filtered also makes funny commercials.

Hydro Flask – (Filter) – Hydro Flask uses a custom engineered Revolve six log filter in their filter water bottles . Hydro Flask’s insulated bottles are 18/8 stainless steel double wall vacuum insulated so you can keep cold liquids cold and the hot liquids hot. The Park Visitor staff were able to test out the bottles and the Hydro Flask bottles were a hit as they really kept our cold liquids ice cold. The bottles are BPA free as well so you can focus on the beautiful nature that surrounds you and not your health on your hikes.

Eco Vessel – Aqua Vessel Insulated Filtration Water Bottle with 100-Gallon Filter – This bottle is also insulated making sure the temperature of the liquid inside is regulated. However, This filter does not claim to remove 99.99% of viruses but still does remove 99.99% of all other pathogens that can be present in water. The filter does sell for a lower price at around $15 and lasts for up to 100 gallons.

CamelBak – CamelBak All Clear Water Purifier Bottle (Purifier) – Park Visitor loves this water bottle. The charge lasts up to 28 days so you are free to roam around in the backcountry. There are no filters to replace which more than pays itself off over time (according to CamelBak, the unit will last 10,000 cycles meaning you can purify 3 bottles a day for 9 years!). And the blue UV light is cool! However, the water source needs to be clear for the UV light to work its magic. CamelBak does offer a pre-filter which strains dirt and sediment out before water enters the main chamber. It is a bit more expensive than the other water filtration bottles but is definitely worth the cost!

Pura – Pura Kiki Stainless Steel Infant Bottle – (Not a purifier or filter) –  This water bottle made it to our list even though it does not offer a filtration system because Pura was the only company with babies and young kids in mind. Pura and Park Visitor both understands that not only adults go outdoors but that families do as well from young to old. The bottles have neat designs with interchangeable color sleeves and are safe for babies. They are all stainless steel, BPA free, and non-leaching.
