MSR Miniworks water filter.

MSR Miniworks water filter.

Postby WarrenH » Sat Mar 23, 2013 7:44 pm

After a request to give my opinion of the MSR Miniworks water filter by one of BNA ACF's most illustrious posters ... I've pulled-out some old shots and taken some new stuff of the water filter, to answer his questions.

My own question that sums up the filter's performance. Would I buy this filter again? ... yes most definitely. This filter has given me good service and I don't ever question if it is up to the job no matter how bad the water quality. The filter is not suitable for filtering salt water.

Is the filter labour intensive to use? ... yes it most definitely is, if I don't maintain it adequately. Without timely maintenance it's performance is as slow as a wet week. If I keep it clean and sterilize it once a week, when travelling, it is first class, quick and efficient. I've had the filter for a few years now and I'm still using the same ceramic cartridge, that the manufacturer expected to have a life of 5,000 filtered litres.

What isn't efficient, is then processing the water after it has been filtered. I boil every drop for 8 minutes. Why for 8 minutes? ... ask a prion.

Now for some shots.

As you can see the filter isn't very big, like a Trangia pot gripper big.

Image

What makes it look big is screwing a 1lt Nalgene bottle onto it.

Image

Filtering farm dam water yesterday on the BNT below mount Tennant. All the creeks, like the Naas (had unlinked stagnant pools or no water at all) and the Gudgenby had two dead sheep in it and it stank. I filtered water at the farm dam at the corner of Boboyan and Sunshine Roads. The long length of the hose works well when I can't get up-close to the water.

Image

Image

After reading here on BNA about covering the inlet with a paper coffee filter, to double the time between maintenance ... this has been spot-on advice. Chapeaux.

Image

Maintenance is easy. Easy to screw apart and to clean each bit adequately. Over the past three years I've only ever rinsed the parts and the hose and scrubbed-down the ceramic cartridge, when needed. It is only the ceramic cartridge that is sterilized by a rolling boil, for 8 minutes. I've been getting between 7-11 litres of filtered water at 1lt per minute, depending on the water's turbidity. Then the filter cartridge needs lightly rubbing down with a Scotchbrite scourer to clean the cartridge, if the flow falters. To keep the piston's O ring well sealed, I give it a light coating of Vaseline.

All the bits exploded (less the hose and hose intake) ... although I haven't removed the needle valve from the red piston housing for the photo. The red crescent that comes off the base if it slides over the filter cartridge then the filter has been worn down by cleaning and then need replacing.

Image

I purchased the MSR Miniworks about 3 years ago, for $135 AU after ordering it from a camping store here in Canberra.

I'll post some shots of where I've used the filter over the last few years.

Warren.

Now you've got my inquisitiveness piqued.


How do people contract prion diseases?

Acquired infection occurs through diet (eating infectious parts of mad cow) or medical procedures (including brain surgery with contaminated equipment), growth hormone injections (which were once extracted from human pituitary glands, which is located near the brain) or corneal transplants. As doctors have identified these routes, medical procedures have changed to eliminate them....

....According to the Centers for Disease Control, 213 Americans died of Creutzfeldt-Jakob disease in 2000, including inherited and spontaneous disease. None of the cases was blamed on eating meat.

From http://whyfiles.org/193prion/5.html

If you really think this is a likely risk in water, I don't see a filter or boiling at a campsite as having any effect.

How to stamp out prions? The list is short, the methods vicious:

Incineration at 1000 degrees C

Autoclaving (steam heating) at 134 degrees C for 15 minutes or longer

Exposure to highly concentrated sodium hydroxide (lye) for 15 minutes in a boiling solution.

Exposure to concentrated bleach for one hour.



BTW

Prions naturally occur in your body, so they are not recognized as foreign and don't stimulate the immune system. They have the potential to cause disease, but won't automatically harm you.

From http://chemistry.about.com/cs/howthings ... 22703a.htm

I don't see this as any sort of risk in the Australian bush from drinking water that is clean, or has been treated by normal methods. If you have other information it would be valuable to all, but please avoid scaremongering.

Warren - Are you saying you still boil the water after filtering? I was under impression that filtering water is a process so you dont have to worry about boiling and can drink it straight after filtering?

Excellent. Just in time for us to consider for our long trip. We already have a steripen, now just need to find something that will remove particulates... :)

il padrone, Peter, sincere apologies. My post to your response, posted that same evening, isn't on this thread. Thanks for waiting for my belated reply.

I've no idea. Boiling to 8 minutes will be the next best thing, to reaching a 1,000ºC takeout? But, I do know that MSR recommends boiling the filter cartridge for 8 minutes once a week when on tour and a Microbiologist who was also a Parasitologist at the School of Biological Sciences at ANU, recommended (many years ago) that I boil water for 8 minutes in this region ... and also a NSWPWS Ranger at Royal National Park when I quizzed him about Botulism in Royal, attributed to the feral Samba Deer, recommended boiling park water for 8 minutes. Who am I to question those who know more about it than me? If you have been reading the NSW Livestock Health and Pest Associations Senior Vet's papers recently, you will know that Botulism has raised its ugly head on the NSW South Coast again, after several hundred native duck were found dead around Nowra in February.

Peter, I presume your comment was concerning prions? Over the last few years I've been exploring the Travelling Stock Routes of NSW. Many of the trails and the trails around home share sections with horse trail and the TSRs with cattle and sheep of course. Simply, stock plus rain & flying dirt equals ecoli. Perhaps some of these shots might help to describe what it is like. Also, here in the SE of NSW and the ACT feral animals especially pigs are a curse to the water courses ... not to mention inconsiderate people dumping and the possible contamination from floods debris.

In a nature reserve, feral cattle have fouled this once pristine little frog pond.

On the Great South Coast Walking Track, that I spent time exploring a possible bike route, riding on the beaches alternating with fire trails, earlier this year. At Poole's Beach, the once reliable water soak, 20m north of the campsite, was not very welcoming ... to me.

I agree, about being in the bush. Scaremongering was not my intention ... but I know what I need to do.

Cheers Mate.

Warren.

PS, Another question. Even after boiling water for 8 minutes, if I don't refrigerate the water, what is that boiled water like in 24 hours time? It's nothing like it was immediately after boiling ... but I'll still drink it.

Got my widemouth Nalgene bottles (supposed to make a good hot water bottle on cold nights) and my MSR Miniworks is on its way from the US.

Wazza if your reading this, how often might the seals need replacing? I ask having seen a maintenance kit (seal replacement kit) on ebay.
Great to know Vaseline is a suitable lubricant for the unit.

Thanks for the blow up of the individual parts.

My Miniworks arrived today.
For anyone looking Bike24 has them here:
https://www.bike24.net/1.php?content=8; ... 45||||||||
88.19Euro or approx $125.87Au plus postage

as well as the popular light weight stove - the pocketrocket:
https://www.bike24.net/1.php?content=8; ... 81;mid=567
25.17Euro or approx $35.91Au

Which for the Miniworks is a bit cheaper than the best Aussie price I can find of $143.95
http://www.hiking.com.au/p/1143243/msr- ... ilter.html
and
http://www.summitgear.com.au/shop/index ... cts_id=546

Another option appears to be bikewagon.com who also has an ebay site.
Their home site lists the Miniworks at $89.99US plus postage.
I've had issues with their communication so havnt used them

For any Taswegians amongst us, there is someone "down there" offering one on gumtree for $120 in Hobart:

Rif, G'day.

I've had the filter for about 28 months. It has been well used and I still have the original parts in service. I've only re-greased the O rings once, that was with a light smearing of Vaseline and that was just prior to my last trip along the BNT during June. The O rings are showing no signs of deterioration, what-so-ever. Nor is any other part if the filter. I try to be as uniform as possible when cleaning the soft ceramic element, so that I get uniform wear, when I'm scouring it.

One thing to be careful of, if you do remove the split-bolts, make sure that they are put back in from the side that they were removed from. If they're put back in from the opposite side, they feel clipped-in, but they will fall out. They don't clip-in well if replaced from the wrong side, and when least expected they will fall out ... like one of my bolts did into the Wollondilly River. Fortunately I recovered the split-bolt because the water was shallow, crystal clear and thankfully slow flowing.

Some places where I got water in cattle country, on the Great Dividing Range, during June.

Fast flow setting: 2L/min or long-life setting: 1.1L/min
Size: 190 x 100mm

MSR Miniworks
Filter: Ceramic plus carbon
Filter life: ~2000L
Flow settings: 1L/min

Both protect against Protozoa and bacteria.
Both are effective against particulates.

Both look like they are designed by a committee that cheated off each other.

Photos not to scale with each other.

I personally have a Katadyn filter, which I bought of Amazon for much cheaper than available in Australia.

I've got the Katadyn too but mine is the non-plastic version...got it from Amazon half price prior to geo-blocking...it's bombproof but not the lightest...I prefer durability.

I have the MSR Waterworks which is essentially the same as the Miniworks (Waterworks has an additional filtration membrane IIRC) and agree it's an awesome unit. I've never bothered boiling afterwards and so far so good. Can't hurt to boil of course except using a little more fuel.
