How we picked / criteria

  • Filtration Class: We prioritized H13 True HEPA filters over 'HEPA-type' alternatives to ensure medical-grade particle capture.
  • Clean Air Delivery Rate (CADR): Each model was evaluated for its efficiency in clearing smoke, dust, and pollen from a 100-square-foot radius.
  • Noise Performance: Because these units sit on desks or nightstands, we only selected models that operate below 45 decibels at peak speed.
  • Smart Connectivity: We looked for 2026-standard features like Bluetooth app integration and auto-mode sensors.
