Durable, Dependable, Clean Water

Ive owned this for 10 years, and have used if all over the country. Screws directly onto my nalgene bottle. The water is clean and maintanence is minimal to keep the filter working. I recently purchased a second MSR and a replacement filter for my original. This is a STRONG recommend.

Excellent filtering

This is my 2nd MSR Miniworks filter. The first took an unusually hard hit (cutting cord on bear line dropping pack 50') which broke the ceramic element. However, the housing, pump, and everything else remained 100% intact.This filters water so well, you'll hate drinking most of the bottled waters out there. ...waters - water, yeah right.... Nothing better than mountain springs.Nothing gets through, and what can will be killed with treatment. Highly recommend for any Backcountry hike or other situation.

Worked well but slow

The filter seems to work great, but its slow. Not so bad if youre filling a 32 oz nalgene. I tried filling a 6l bag, and it took a while. Definitely not ideal. I realize pumps are going to be limited, and while Im happy with this as a replacement, definitely want to make sure you plan for time of doing a large volume of water.

Easy to use

My son recommended to us and it is a good product. Easy to use in the stream. Bought 2 qt bottles to attach. The hose is long enough.
