The average person should drink between 2 - 3 litres of water every day, and to prevent getting sick the water needs to be clean and free from bacteria, protozoa and other nasties. Access to clean water isn't a problem when you're at home or work, but if you're out on a week-long trek through the wilderness or backpacking through a developing country, it can be much more difficult to obtain.

Here are some great reasons to recommend SteriPEN portable UV water purifiers to any customer looking to buy gear for their next adventure trip or overseas journey.

• SAVE ON WEIGHT - Water is heavy, and the last thing you want to do is lug around 10-15 litres of the stuff on your week long outback adventure. If you know where water can be found along your route, all you need is a SteriPEN and a 1-litre container and you'll be able to travel lighter and still have access to clean drinking water. It takes just 90 seconds to treat 1 litre with a SteriPEN, and they are also quicker, lighter and more reliable than chemical or water filter solutions.

• SAVE ON MONEY - Having to constantly buy bottled water when overseas can soon become an expensive endeavour. A SteriPEN is good for thousands of litres of water treatments, saving you money in the long run.

• SAVE THE ENVIRONMENT - Plastic bottles account for millions of tonnes of landfill and CO2 emissions every year. Use a SteriPEN in conjunction with a reusable drink container such as a Klean Kanteen, and you'll be saving on your carbon footprint as well as on money.

These are just a few of the reasons why SteriPENs are a great choice for travellers both in the wild and abroad, so the next time a customer enquires about the best water treatment product on the market, be sure to recommend SteriPEN.
