Katadyn Micropur Forte Water Purification Tablets Review

Carrying water on the trail is only half of the equation. In many places we hike, at least in western countries, we take for granted we will have access to good quality supplies of clean water right? While the answer is usually yes this is not a guarantee and what we see is not necessarily all that we get.

I travelled through India a few years ago and managed to pick up a case of Giardia that took me six weeks on a fairly strong course of antibiotics to get rid of; an experience that I never want to repeat. Don’t be fooled here, Giardia exists in Australia and there have even been outbreaks in town water sources. As a result of this I am extremely cautious when collecting water on the trail and no matter how clear the water may appear, I will always use some form of water treatment just to be on the safe side.

Using chemicals to treat water is by far the lightest option for the ultralight hiker but as always there are drawbacks. The Katadyn Micropur Forte Water Purification Tablets (along with the liquid version) is the most commonly available chemical water treatment for hikers in Australia. Brands like Aquamira also exist but most specialist outdoor stores seem to opt for the Katadyn products.

These tablets work by chemically killing of any biological nasties in the water. The tablet version is the easiest to use; just add one tablet per litre and wait for 30 minutes before drinking (for viruses and bacteria) or two hours for Giardia. So while this is a great water purification option if you only have one container then you had better hope that you are not very thirsty otherwise you may find yourself taking a risk. As an example if you drink four litres of water per day the packet of 100 tablets will last 25 days. For people like me, paranoid about Giardia, this means I would operate with at least two bladders and drink from one while the other is being treated. Once treated the water is good to use for up to six months.

Apart from the length of time required to treat the water the other main issue is that it doesn’t get rid of any solids in the water which means that you may end up with gritty water or food. To solve this issue pre filter with either a sieve filter that you can buy from the outdoor stores or use a buff to pass the water through to pick up any chunky bits.

One other issue people often don’t think about with this product is cost. If you are like me and always filter/purify the water then this product costs just on 55¢/litre and given the amount of hiking that I do would add up to nearly $550 AUD per year which starts making products like the MSR Guardian Purifier at nearly AUD $700 AUD looks cost effective in the long run considering it also gets rid of the chunky bits as well.

Having said that I will always tend to carry some of the tablets on my longer hikes as a ‘just in case’.

Katadyn Micropur Forte Water Purifier Tablets (100 tablets)

We Like

  • This water treatment option is about as lightweight and compact as you get at around 22 grams for 100 tablets
  • This is about the easiest water treatment product to use so you are unlikely to make a mistake
  • Kills viruses so if you have any doubt about water quality this is a good option

We Don't Like

  • Expensive when used long term. While one litre only costs around 55 cents to treat if you use a 1000 litres per year, it gets very expensive
  • Doesn’t filter out the solids in the water
  • At best you need to wait 30 minutes before you can drink. If you have any concerns about organisms such as Giardia then you should wait two hours

Best Uses

This is a great option just in case your main filter goes down or for when you have a concern about viruses being present in the water; particularly when travelling overseas
