As easy as a sierra cup!

Rating:*****
When I started backpacking I used a pump type filter. It worked Ok but was kind of heavy and slow while on the trail.
I next switched to chlorine dioxide which was much lighter but required about 30 minutes to treat the water. This was Ok in camp but on the trail I really didn't want to have to wait for a drink.
The Sawyer filter has worked great! The filter plugs into your hydration bladder tube. You just fill your hydration bladder and your ready to drink. Great when you are trying to make time on the trail. I found that it also works great in camp when I'm going to heat water for freeze dried food or coffee. You just hold the hydration bladder like a IV bag and squeeze the byte valve. Gravity flow fills the pot as fast as my old filter.
After using the filter for 2 years I haven't noticed any decrease in flow. I've only used it in the sierras where the water is crystal clear so I'm not sure how it would do with cloudy water. This filter has been one of the best changes I've made in the last 30 years of backpacking.

It's so simple you'll doubt it works!

Rating:*****
I too started with pumps, which weigh too much. I dabbled with the Steri-Pen, which turned out to be good in theory but questionable in practice.
The Sawyer is simply the best at water filtration. While it can't treat viruses it does grab all bacteria, even crypto. In other words all the bad stuff you'll find in the US since we don't have a big virus problem here in the states.
While other fellow backpackers are pumping, or waiting for their chemicals, I just dump my bladder into a water source and out comes clean water free of particulate and bacteria. I also know of nothing lighter.

Revolutionary!

This product will change the way you look at water purification. I spliced my camelback and attached filter to line. No taste, little maintenance and no special requirements to store.

Negative Reviews:

Look for the newer model

Rating:**
Sawyer guarantees 1 million gallons but expect only about 10-15 gallons until you lose about 1/2 the flow rate. Even backwashing with HOT water did not improve the rate much. Dissappointed that Sawyer does not sell just the replacement membranes. (The 1 million guarantee is for defects). Important note is REI is selling the "old" SP122 model (all black). Buy the SP123 which is Black & Gray. This came out 2 months ago and is advertised to have a much better flow. If you do intend to buy a in-line filter & use a hydration bag, you will really need to squeeze the bag to increase the flow rate. I went back to the filter bottles. Good luck.

High Flow rate, but leaks horribly.

Rating:*
I purchased one of these filters and it leaked at the seam where the two parts of the case meet. So I returned it to REI for another one. The second one also leaked in the same place. My concern is whether the leaking water is clean or dirty and since I don't know, I will return this one too. This leaking filter would be impossible to use in the winter. It would be a great product if it did not leak. It is easy to use and has a very high flow rate.
