Info & Guides

Designed for expansive living areas, the Coway Airmega 350 Large Room Whole Home HEPA Air Purifier pairs high-capacity airflow with advanced three-stage filtration to keep your indoor environment healthier around the clock.

At its core, Coway’s HyperVortex filtration system and custom HEPA filter targets airborne particles and odors while maintaining whisper-quiet operation and efficient power use, giving you dependable, whole-home purification in a compact design. It comes in either beige or white.

Key Features and Benefits of the Coway Airmega 350 Whole Home HEPA Air Purifier

  • Large-Space Coverage: Delivers one air change per hour in rooms up to 2,640 square feet, or two air changes in rooms up to 1,320 square feet, for high air-purifying capacity with a single appliance.
  • Three-Stage Filter: A vacuumable pre-filter, Green True HEPA filter, and activated carbon filter work together to capture particles, odors, and smoke.
  • HyperVortex Airflow: Optimized internal design pushes purified air quickly across the room, giving you faster relief from dust, allergens, and pollen.
  • Smart Operating Modes: Auto, Sleep, Eco, Turbo, and three fan speeds let you balance noise, energy use, and cleaning power with a tap of the control panel.
  • Real-Time Air Quality Monitor: An onboard sensor with a color indicator keeps you informed of changing particulate levels and automatically adjusts the fan speed when Auto Mode is active.
  • Quiet Performance: Runs as low as 21.5 dB during Sleep mode to a maximum of 54.7 dB, keeping bedrooms and study areas undisturbed while you rest or work.
  • Long Filter Life: Replace the Green True HEPA and carbon filter only once a year under normal use, simplifyig ongoing maintenance.
  • Lightweight, Modern Design: Weighing just 17.2 pounds and standing 23 inches tall, this compact, reliable air purifier easily fits in any room.

Quiet Whole-Home Comfort

You shouldn't have to choose between power and peace. The Airmega 350’s sound profile starts at a barely noticeable 21.5 dB in Sleep mode, ideal for bedrooms and dedicated workspaces, then scales smoothly through three manual fan levels up to Turbo for rapid purification with a max noise level of 54.7 dB. Its upright, 12 x 12 x 23-inch frame tucks neatly against a wall, and two neutral color choices, White or Mocha Beige, integrate seamlessly with modern or traditional décor.
