We test in real homes. Not in lab chambers.
Every product is scored 0–10 across Filtration efficacy, Noise (dBA at three speeds), Ease of maintenance, Energy use, and Smart features (when applicable). Tested in real bedrooms, basements, and nurseries with calibrated air quality monitors over 30+ days. Manufacturer specs are never trusted at face value.
