HEPASilent electrostatic+mechanical filtration moves a lot of air very quietly at low wattage, excellent CADR-per-dollar, small footprint, and strong real-world particle-removal test results.

Gemini Exceptionally high CADR for its size, whisper-quiet operation, sleek customizable fabric pre-filter aesthetics, and excellent energy efficiency.

Where Blueair Blue Pure 311i Max falls short, per the models

  • Gemini Clarify and certify the electrostatic HEPASilent filtration technology to match true medical-grade mechanical H13 HEPA standards.

Superb quiet performance — moves more clean air per decibel than nearly anything in class, energy-sipping, lightweight, with washable fabric pre-filters and simple app control around $230

Gemini Extremely quiet operation due to proprietary HEPASilent technology, powerful 360-degree air intake, and an attractive washable fabric pre-filter.

Where Blueair Blue Pure 311i Max falls short, per the models

  • Gemini Lower the relatively high price of its proprietary replacement filters to reduce the lifetime cost of ownership.
