MSR MiniWorks/WaterWorks Ceremic Filter Element for Sale, Reviews, Deals and Guides

An exact fit for my old and favorite pump filter. Looks to be the same quality as the original and only time will tell if it lasts and performs as well as the original.

Similiar to others' reviews, it IS in fact a great filter. You can fill up a Nalagene quickly (you just need to clean it regularly) and the filter itself lasts a very long time... unless you drop it on the ground/floor and it cracks the ceramic. I've done this to 2 of these filters so I now use a steripen...better considering my track record.

It filters out unwanted flavors that mother nature mixes up and is fresh. The only complaint is that the ceramic filter is weak structurally. It does not take a beating, so DO NOT drop it on a rough and/or hard surface. It will crack like mine did and compromise the integrity. However, I am very happy with the filter's performance and WILL NOT be changing.

What can I say, it is a filter cartridge. It works great. It is super easy to replace. You just drop it in. Done.

The MSR Miniworks and WaterWorks uses this ceramic filter that will last years and years if taken care of properly. There a few downsides to the filter though. Replacements are expensive, though not relatively so, since a single ceramic filter can potentially last you several years or more. Also, they are fragile. Do not go to sleep with a little water in this filter if it is going to get below freezing at night. The freezing water will swell into ice and crack the filter. Sleep with this filter if you're going to see freezing temperatures. The filter is field maintainable/cleanable. Pull the ceramic element out, and *very lightly* brush it with a small piece of Scotch Brite, or something similar that has a bit of abrasion to it. Do not scrub the hell out of the filter. It'll reduce its life significantly, and won't get it any cleaner than a light cleaning. The goal is to remove the funk covering its porous surface, not to sandblast it. Also, once you're home, take the filter element out and let it dry, and take the time to clean the filter body. 30 minutes of maintenance will keep this filter and element lasting a long, long time. With proper care this filter is, dollar for dollar, the most affordable and reliable filter around.

I got this to replace the one that I dropped and cracked. I wish that these filter were a little more rugged.

Please read your manual. I used to work in a gear shop, and every last one of these we sold was to someone who didn't need it, or needed it because they mistreated their old filter. Step 1: Don't need a new filter: I've had a MiniWorks for 11 years, if you let it dry out after trips (prevent mold), don't let it freeze with water in it, and make an attempt to get clear water into it, it'll last a decade or more. Once you think you need to get a new one of these, check the MSR manual (online too!), and scrub off the surface according to their directions. Presto, I probably just saved you $40. Scrub it off, and when you do that, just bite the bullet and get new O-rings for it (normally less than $5 at your local MSR rep). Also, make sure that you've got the prefilter on the little floatie. That'll again extend the life considerably.

Bought a replacement after the original filter in the unit broke when I dropped it a couple feet onto a rock. Wish the ceramic filter was a little more durable it would be nice if replacements were cheaper. Thus the 3 stars... That said, I am still overall very happy with the MSR Miniworks filtering speed and how easy it is to use and maintain. That was my first problem with it after years of good use.

The filter lasts a long time!!! Easy to maintain and clean!!! Loved it on all the trips!!!

The only reason why I gave this three stars is because the price sucks. Other than that this filter beats all other filters that I have owned. It is extremely fast and makes some super clean (and tasty!) water. Sometimes I have to clean the filter after every single 32 oz bottle that I fill but cleaning it is so easy that I don't even consider this a negative towards msr.

The filter in the unit clogs fairly easily in silty water. It is also fairly easy to clean with the green scrub pad and works well when clean.
