Start with an assessment
Name the change you want to make
Taste, odor, cloudiness, visible particles and deposits are worth describing separately. Let us know when the change began and where it appears. These observations can guide the conversation, but appearance and taste alone do not establish which substances are present or whether the water is unsafe.
If you have water-test results or information from your supplier, bring them to the discussion. Identifying the concern helps you compare the stated capabilities of a treatment system with an actual need. A filter should be selected for what it is designed to address, rather than for a promise to remove everything.
