I bought this 18 months ago. I use my water filter jug for all other uses but for drinking water this is ideal. Easy to keep clean and the filter can be reused by cleaning in boiled water once a week.  I take it everywhere I go so always have fresh drinking water. The taste encourages drinking water too and certainly prevents dehydration when out and about in hot weather. . I cannot praise this filter water bottle enough.  Definitely a good buy.
