How does the water hardness test work?

Very easy in two steps:

  1. Order free BRITA water hardness test strips using our form.
  2. Place the test strip in cold, unfiltered tap water. Wait until the strip changes colour. Compare with the included colour chart and you'll know your water hardness!
