Filtration Technology

The Mila Air 3 uses an H14 HEPA Overreactor filter, which is a grade above the H13 filters found in most consumer air purifiers , capturing 99.95% of particles at 0.3 microns versus 99.97% at the H13 level. The integrated carbon filter adds a chemical filtration layer that actively absorbs formaldehyde, VOCs, and household odors.

This dual-stage approach covers everything from fine dust and pollen to gaseous pollutants, making it more comprehensive than purifiers relying on HEPA alone.

CADR & Sound

Noise & Performance

The Mila Air 3 covers up to 595 sq ft and delivers 4.8 air changes per hour, meaning the entire volume of air in the room passes through the filter nearly 5 times every hour. Sleep mode is designed to minimize both noise and light output for nighttime use, though specific decibel ratings aren't published , something to keep in mind if you're particularly noise-sensitive.

For living rooms and home offices, the auto mode dynamically adjusts fan speed based on the air quality sensor, so it ramps up only when it detects pollution.

The dedicated smartphone app provides remote monitoring, scheduling, and real-time air quality data, while auto mode handles fan speed adjustments automatically.

Additional controls include sleep mode for nighttime operation and a child lock for households with curious kids, though voice assistant integration details should be verified with the manufacturer.
