Methodology

How We Review Devices

We prioritize evidence quality, practical dose usability, and long-term adherence factors over marketing copy.

• Panels: Power, value, EMF transparency, features, modularity, coverage.
• Masks: Fit and comfort, coverage, routine ease, modes and use cases, build quality, value.

Where evidence is uncertain, we state uncertainty explicitly.

Commercial links are disclosed separately and do not define rankings.
