Drinking water regularly is essential to survival, as water makes up around 70 per cent of a persons body, but debates continue on water quality and filtration options, Health News Digest reports.It says the variety of water filtration and softener options can be daunting, but provides information from experts to help clear up the confusion and misconceptions.According to the news provider, bottled water, like tap water, can reasonably be expected to contain at least small amounts of some contaminants, making it no more or less safe to drink.It goes on to cite the Water Quality Association, which says that four out of ten in the US use a water treatment unit and adds that not all filtration methods are the same.Finally, home filtration can cost less than buying bottled water, Health News Digest concludes, making it a viable option.Water quality is an important issue that should not be taken lightly, the website states.It recommends considering products by companies such as In-Sink-Erator and Tapworks.According to the Food Standards Agency, UK residents should drink around 1.2 litres of fluid every day.
