Recent Water Treatment Product Reviews

Katadyn BeFree

rated 5 of 5 stars This handy water bottle and filter allows you to hydrate on the go, literally, and allows you to drink from any water source. Water tastes great and flow rate is good. This is a new on-the-go water filtration system. The Katadyn purifier is a personal and portable water filtration system designed to give you safe drinking water on the go. Now I am a believer in occasionally drinking unfiltered mountain water from very specific sources (and man is glacier fresh water tasty), but now with this… Full review

Katadyn BeFree

rated 5 of 5 stars Great choice for every outdoor pursuit! The award winning Katadyn BeFree water bottle and filter gives you the freedom to drink anytime, anywhere. The collapsible .6 liter flask packs small and fits into tight spaces. It’s a great backup water filter, but can readily be converted into your primary water filtration system. Description: The Katadyn BeFree Water Filtration System, a compact water bottle with integrated hollow fiber filter, makes a great choice for outdoor pursuits. The Katadyn BeFree… Full review

Sawyer MINI Water Filter

rated 4 of 5 stars Sawyer Mini Water Filter is a small lightweight filter. It is great for backpacking and hiking. The Sawyer Mini WaterFilter treats dirty water when you squeeze the water through the filter. It doesn't take long to filter. All you need to do is put it together and squeeze. It is plenty of water for me, but if there was a group of 4-5 I would probably have to refill it 2-3 time. Treating the water is very simple all you have to do is put it together and squeeze. It works constantly and always well. Full review

LifeStraw Mission Gravity Water Purifier

rated 1 of 5 stars The Lifestraw Mission gravity purifier is overall an OK performing filter, and I would probably trust it to adequately filter any water source not contaminated with chemical contaminants, radioactive material, etc. However, it is not without its flaws and quirks. Filter functionality alone, I would rate this filter 2 or 2 1/2 stars, but when its other flaws are taken into account it brings my rating of this filter down even lower. If someone asked me to describe the Lifestraw Mission in as few words… Full review

Platypus GravityWorks Filter System 4L

rated 5 of 5 stars Lazy Man's Water Tanker! In planning for a 4-day backpacking trip on the Ouachita Trail in Arkansas we noticed a 10-mile stretch with no water supply (with a mountain climb). Looking around this system seemed like it might be the ticket—4 liters, let gravity do the work instead of pumping. Needless to say the morning we hit the trailhead it was snowing with ambient temp of 15°F. The high that day was 22°F. I took the filter from the system and put it inside my shell to make sure it didn't get… Full review

Katadyn Combi

rated 5 of 5 stars Great device. I have a few Combis. Used one with mountain water in Auburn, California, and didn't have a problem.  In fact, the water tasted amazing. Full review

Sawyer PointOne Filter with Bucket Adapter

rated 5 of 5 stars A very adaptable filter for groups. My Katadyn cartridge filter would sometimes plug on long group trips and wouldn't backflush. This filter costs what a replacement Katadyn cartridge would cost. However, it back-flushes beautifully and has been used with a 10 liter water bag for group water on several trips and is still going strong. It is lighter and packs smaller than my old one. Full review

MSR Guardian Purifier

rated 5 of 5 stars Simply the best water filter in the world. I have used water filters for decades. My first one cracked when it froze. I have used two MSR MiniWorks with great results. It was great to be field repairable and field cleanable BUT filtering water was slow and required a lot of effort, usually at the end of a long hard day! Enter the MSR Guardian! Less than half the effort of the MiniWorks and at least twice the speed. For these two features alone this filter would be the winner but there is sooo much… Full review

Sawyer MINI Water Filter

rated 4 of 5 stars This is a very light water filter with adequate flow if you're focused on minimizing the base weight of your pack. I have been focused on getting the base weight of my pack down under 20 pounds and one of the changes I made was going from a pump type water filter to the Sawyer Mini water filter. In general I am happy with the Sawyer Mini in that it does the job and only weighs in at about 2 oz. The filter comes as a kit and includes a syringe for washing the filter using a back flow, a 16 oz squeeze… Full review
