The best way to get pure water is via steam distillation using a water distiller. This method leaves you with water that is purer than any bottled water and far far cleaner than tap water. It also beats any other filtration system and provides you with adequate amounts of clean drinking water and a great price. Visit my store to find a home water distiller at a great price, click on the water page. In your first year of ownership it works out at around 9 pence a litre so you'll quickly recoup your investment costs compared to the expense of buying quality bottled water.

Sounds lovely which is why we've all shifted to bottled water. I've always believed we shouldn't have to pay a premium to drink clean water that is so important for our health. Put quite simply, its essential to long term health that our water is clean in order to avoid our body having to work overtime as a filtration system.
