Portable Water Filter
- Thread starter keluangus
- Start date
Get a Katadyn Pocket, much more expensive, but good for 13,000 gallons, opposed to 200 gallons. Start adding costs of replacement filters for models like the Hiker Pro, and it starts making sense. 0.2 micron filtration.
Also take H20 purification tablets. Can't hurt.
keep a few in a small pill vial, you may find yourself somewhere, without water , or with questionable water, you may have to wait 30 minutes for the purification tablets, but better to be thirsty for 30 mins, and have that extra insurance.
Third World Bottled Water = BEWARE!!
If you are staying in decent "name brand" hotel, they will ensure the bottled water is pure, it will be more expensive, but this is no time to skimp, use their bottled water! WHY? Because there are people in india who will either:
A. Re-fill water bottles and sell them for cheaper prices.
or
B. Will purchase new empties, and fill with the local swill, maybe running it through a 5 or 10 micron filter, or charcoal, to simply get rid of the cloudiness.
Even at restaurants in India, don't trust their bottled water!
Bring your own from the hotel.
They buy theirs at the lowest prices, and there is higher likelyhood it's re-bottled swill. (The higher end western restarants are more trustworthy).
Beware foods prepared with water. Soups that weren't brought to a boil , WILL give you the trots, it's highly likely.
if you will be static in your same hotel room for weeks, you can set-up a table top purifcation unit.
Stick with hotel bottled water, and only that water which is garanteed by the hotel.
Even if you do all of this, you may still have a day or two of the runs, but it's better than cholera or ending up in an Indian hospital. if the H2O doesn't kill you, the hospital facilities surely will.
My brother in law was just there a couple months ago, he gave me the scoop.

I have an excellent article about water filters, effectiveness, and what makes people sick. If you want it, email me at dmontierth@processengr.com
This article was published in a magazine (a canoeing magazine of some sort) and was also posted on the marathonceramics web site for a while (at least 5 years ago). It contains some generic test results from bacteriological testing of various filters. Since the test was done by MSR, they only identify their products in the chart (I have the full report, but agreed to not disclose it). They filtered river water to the end of life of the cartridge, then challenged the used filter with a very high dose of a small bacteria.
While you may say that the article is biased towards their products, note that the top performer was not theirs.
As for the Katadyn Pocket filter's capacity, I have to disagree with their marketing. It would not reach 13,000 liters even if you only filtered clear tap water. I have one, and it is a great filter. It will last longer than anything out there (roughly 3 times as long as the MSR filters), but the claim of 13,000 is exaggerated. Anyway, filter life is totally dependent on the quality of the water you start with. The PF has been used all over the world for over 60 years, and I think you could say it works well.

Aquamira, chlorine dioxide tablets (Katadyn or Potable Aqua), Sweetwater purifier solution, or plain bleach make a very good backup to a filter when you are dealing with questionable water quality, such as in areas that are populated or near popular campgrounds. The concern is human viruses, which are largely removed by a good filter, but not completely. These chemicals will kill the viruses, the filter will take care of the rest.

Hey Guys...
I haven't read all of the replies so,
If no one has mentioned it before the MSR pump has a ceramic filter and you can also get an Iodine chamber for it....
The ceramic filters out the particulate matter and the Iodine purifies the water.
One of the nice things about the MSR pump is that you can reverse the flow, and thus cleanse the ceramic filter once it gets clogged..
I'm not sure if other pumps have the same features,, but these are Great features to watch out for...

Since one poster has mentioned "bleach" and two iodine, it may be good to recall that neither "bleach" nor iodine is effective on crypto. I presume crypto is not a problem restricted to North America.
Crypto may be in other areas of the world. I don't know. But there are other cysts similar in nature. Iodine and bleach don't generally work well with cysts. The newer chlorine dioxide tablets (Katadyn or Potable Aqua) as well as the MSR Miox, have been demonstrated to work, but they can take a long exposure time when the water is cold and cloudy - like 4 hours. They work a lot faster, maybe 30 minutes, with clear water. The cysts are easy to remove with a filter, though, since they are relatively large.
Normark - the MSR Miniworks does not have iodine (where do you get an iodine chamber?), and it is cleaned by removing the ceramic and brushing or scrubbing it. It does not back flush. It does have a very good block of carbon (in addition to the ceramic), which works well for removing flavor and odor in bad water.
