Yes, you may still need a water filter even if your water tastes and smells fine. Many dangerous contaminants—such as lead, arsenic, PFAS ("forever chemicals"), and certain pharmaceuticals—are tasteless, odorless, and invisible. You cannot detect them by taste, smell, or appearance.
Even if your water meets current EPA standards, it's important to understand that:
- Not all contaminants are regulated. For example, PFAS chemicals are only recently being addressed in some areas, and many others remain unregulated.
- "Acceptable" levels may still pose health risks, especially for vulnerable groups like children and pregnant women, or with long-term exposure.
- Standards do not account for the combined effects of multiple contaminants, which may interact to increase health risks.
- Regulations may not reflect the latest scientific research on the health effects of certain chemicals.
For these reasons, using an appropriate water filter can provide an extra layer of protection beyond what's required by basic compliance.
