MSR MiniWorks/WaterWorks Ceremic Filter Element reviews and deals for sale

Solid choice!

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.

Great but beware the forces of Gravity

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.

Great Filter, But Be Careful

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.

Easily Replacable

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

Fragile when not in the filter, but bombproof otherwise

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… read more 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.

This is a filter that hasn't been used yet, next to one that is ready to be replaced.

Fragile

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

Before you buy this READ THIS

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… read more 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.

Fragile...

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… read more after years of good use.

Worth the cash!!!!

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

Works Great

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.

Mini Works

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.

I've had an MSR Waterworks (with the additional paper element) for years. On the last trip I dropped and broke the ceramic element. Bummer for that trip, but when I got home I checked my gear box and it I had two replacement elements which I had purchased on sale when a local store was going out of business. One looks exactly like the ceramic element I busted, with charcoal inside.… read more The other appears to be charcoal on the outside - can't see inside. My question is are these two filter elements equivalent, or are meant for different levels of water quality and filtration?

I have an older MSR pump filter that says "MSR #205" on the removeable filter. It uses a big "O" ring on both ends. Can I get replacements for this?

Greetings, What are the differences between the MSR Waterworks, the Waterworks II, and the MiniWorks EX? We use, and dearly LOVE an old Katadyn Pocket filter, but recently got a new Waterworks for a very good deal. Your thoughts and comment will be appreciated. Thanks, and God Bless! Every Good Wish, Doc

I just purchased a used miniworks and the filter is an orange or light rust color. Is this a normal color for some filters or is it dirty? I used a scratch pad lightly but when it did not seem to change color, I stopped. The web replacement filters look white.

I bought my Miniworks filter about 4 years ago and I've filtered more than 500 liters of silty canyon water and I've just bought a replacement cartridge back in june and I've only used it twice and both times it has screwed me over and the results have been stomach cramps and dehydration. There is a white seal around the top of the cartridge that is protruding out and I'm wondering… read more if it's a defect cartridge. The filter won't put out any water no matter how much pumping I do and I've cleaned the whole unit several times and boiled the cartridge twice to try and revive it... Any ideas?

I have an old MSR Miniworks, non-EX filter housing with the blue top and was wondering if the EX cartridge works with the old style pump. There is an O-ring on the top and bottom of the old style filter and only one on the bottom of the new one. Also, does the new maintenance kit contain everything I'll need for the old filter housing? Thanks!!
