Keep your water working as hard as you do.
The Pure Clear Pure Explore water filter replacement cartridges are designed to keep your filtration system performing at its best, wherever life takes you. Whether you’re travelling, training, working outdoors or simply upgrading your everyday hydration, these cartridges ensure you’re always getting clean, great-tasting water without compromise.
Each cartridge uses advanced multi-stage filtration to remove bacteria, viruses and a wide range of unwanted contaminants, so you can drink with confidence in more places. Just as importantly, they’re built for consistency — delivering reliable performance from the first use through to the last.
Swapping out your cartridge is quick and straightforward, meaning less downtime and more time getting on with what you’re doing. It’s a simple upgrade that keeps your water filtration bottle working exactly as it should.
Because clean water shouldn’t be a one-time solution — it should be something you can rely on every day.
Most filters that we see in todays market are Ultrafiltration (UF) filters combined with a carbon block. If you are looking for a filter to protect you or your family from outdoor water source contaminants it must protect from Waterborne Viruses, not just Bacteria, Parasites and the other usual contaminants.
In todays world of clever advertising, it is easy for companies to distract you from this fact. Our filter is as thorough as a filter can be, and our advice is clear, read the filter details before you purchase a filter bottle. Does the filter remove PFOA’s, Viruses, Trace Pharmaceuticals, Endotoxins and Chemical reduction? If not, then you are at a very real risk of these contaminants that are present in our water sources and they can make you seriously ill.
At Pure Clear® 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 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 periods of time bacteria can grow within the filter itself and become harmful. The carbon block that filters most of the real unpleasant contaminants does not have the same shelf life as the filter itself, usually the carbon life is 200 litres but because the long life filter is advertised at 2000-4000 litres customers think it is safe to use for that amount of time, they are wrong.
Therefore, we keep our pure explore water 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. Description goes here!-water
