SteriPEN water purifiers use a germicidal UV light to disinfect water, killing 99.9999% of bacteria and leaving no aftertaste.
How it works
SteriPEN uses a short wave germicidal UV light to purify water. The UV light disrupts the DNA within bacteria, viruses and protozoa, rendering them unable to reproduce, and therefore harmless. In clear water the SteriPEN will destroy over 99.9999% of bacteria, 99.99% of viruses and 99.9% of protozoa.
Although you may have never heard of UV water treatment, you have probably benefited from it. UV water treatment is increasingly being used by the bottled water and beverage industries to ensure purity. UV treatment is very effective and leaves no aftertaste, making it ideal for long-term use and for bottled mineral water. So next time you buy a bottle of water, or take some from the water cooler at work it is highly likely that your drink has been UV purified.
