Filters

At Pure Clear Filters we do not believe in long life filters for use in filter bottles. Long life filters have a tendency to repeatedly block and suffer an increased pull resistance (it becomes more and more difficult to draw fluid through the filter as the filter life increases). Many water filter bottle companies highlight statistics of the filter performance after just a short period of filtration time, they do not offer the statistics of the filter towards the end of its life. Imagine a battery full of charge, producing a large amount of power, compared with a battery at the end of its life, producing little power output.

The long life filter performance will change over time, and the longer you use it, the lower the filtration performance will be. Long life filters tend to be hollow (UF) and over a short period of time bacteria can grow within the filter itself and become harmful.

Therefore we keep our filter life short. We recommend you change our filter after 200 litres or 2 months, which is the equivalent of 400 standard plastic 50cl water bottles that cost on average £1 each. If you calculate that, its £400 in plastic water bottles vs the cost of our water filter, you can save huge amounts of money and the environment at the same time. We even have a month indicator on the filter housing to remind you when you put the filter in the bottle so you don’t change it too early.
