MSRMiniWorks EX Backcountry Water Purifier System

It delivered good water - I didn't get sick! :)

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.

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.

Very based, worked great and was easy to use. Satisfactory.

The filter seems to work great, but it’s slow. Not so bad if you’re 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 I’m happy with this as a replacement, definitely want to make sure you plan for time of doing a large volume of water.

This filter worked great on my five day trip. Pumped water out of the lake and it tasted like the water out of my reverse osmosis system at home. It attaches nice to a wide mouth water bottle. I have a 32 oz nagelene and 24 oz under armor and it attached fine to both of those. My first few bottles filled pretty fast but after that filling bottles was kind of a slow process. The water was fairly clean to begin with as I got it from northern Lake Michigan. But all in all worked great.

This thing pumps faster than 1L per minute as long as you pump from relatively clear water (why wouldn't you?). Water tastes great, it packs down small, cleaning is a breeze, and it is 100% field serviceable without any tools. If you're looking for a filter, get this one.

great value and great product. second one i have owned first was stolen from my vehicle. was so good i bought the same one again

D’une bonne grosseur et fonctionne super bien.

Bought this for my son's backpacking trips. He hasn't had a chance to use his yet but he has used them before with his Cadet trips and loves it, that's why I bought this one specifically.

received the product with broken ceramic filter. tried contacting manufacturer but no response

I consider this a necessary item for travelling especially in an emergency. I've not tried it yet but it came HIGHLY recommended by a good friend who uses it in their daily lifestyle while they're travelling off grid on horseback.

La pompe ne se charge pas. Il y a toujours de l'air dans le cylindre.
