Start with the evidence
Identify the concern before the equipment
Tell us about taste, odor, visible sediment or recurring residue, and whether the issue is at one tap or throughout the house. Those observations are useful for planning, but appearance or taste alone cannot establish everything present in the water.
Relevant water-quality information helps narrow the choices. Share any recent test results or information from your water supplier, along with the details of an existing filter. If a particular substance is the concern, the selected system needs documented performance for that substance rather than a broad promise of cleaner water.
