When posing the question, ‘Should I filter my tap water?’ or even ‘Why should I filter my tap water?’ secondary questions must also be considered: ‘Do I want to reduce my carbon footprint and minimise plastic bottle waste?’. Likewise, ‘Am I concerned about the presence of sediment particles, chlorine and other chemicals, parasitic cysts giardia and/or lead in my tap water?’ If you answered ‘Yes’ to either of the secondary questions, then you also have the same answer to the first question.
