Choosing the Best Kitchen Water Filter 2020

What determines the best choice when it comes to deciding on the best kitchen water filter? Well, there is no one answer as individual circumstances & requirements will differ. There are however certain necessary criteria common to all:

  • Cost Effectiveness – Not the same as being the cheapest, but that a system should give maximum dependable service relative to the cost of purchase and the ongoing running costs.
  • Ease of Maintenance – Which ever the system installed, filters will require changing. With a good filter design this should be a straightforward and quick operation. Complicated filter changes are one of the reasons that many users do not maintain their filter effectiveness.
  • Availability of replacement filters – there’s nothing worse than buying a cheap water filter and going to all the trouble to install it only to find 6 months later that the required replacement filters are unavailable.
  • Dependable established brand. Reliability is a major factor when you are depending on a product for your health. Having technical backup available gives peace of mind if any issues arise.

With these criteria in mind let us look at what in our view represent the 6 Best Kitchen Water Filters 2020. These have been selected to cover the broadest range of filtration requirements and budgets.
