After a couple of years absence, it’s good to welcome Steripen back onto the website. Steripen is a UV water purification system. Principally designed to ensure that clear water does not contain bugs that will make you sick, although a pre filter option is available. A purifier (or sterilizer) is different from a filter. A sterilizer stops the bugs in the water from reproducing by sterilizing them with UV light. Sickness is generally caused when the bugs in the water reproduce at a tremendous rate in the ideal conditions offered by your stomach. The bugs are not removed from the water by a sterilizer.
A filter removes any particle (down to a certain size depending on the filter used) from the water. This particle can be a bug or organic particle like silt. Everything caught by the filter is physically removed from the water. A filter is a better option if you will not always have access to clear water but can be more work if you are always filtering clear water.
Treatment times are broadly similar for a good filter and Steripen although a pump filter is physically more work, which becomes relevant if you have to filter 10 litres a day, which is pretty normal for 2 people physically active in a hot climate. To make the best choice for you, it’s important to consider the condition of the water which you will be wanting to drink.
We have 3 models of Steripen.
