The Coway Airmega 250 is engineered for large spaces, covering up to 1,860 square feet in one hour. Its HyperCaptive filtration system combines a washable pre-filter, activated carbon layer, and a True HEPA filter that traps 99.97% of airborne particles down to 0.3 microns—directly addressing pollen, dust mites, and mold spores that trigger sinus infections.

The real-time air quality indicator uses a color-coded LED to show pollution levels at a glance, so you know exactly when your sinuses are under threat. Smart Mode automatically adjusts fan speed based on the sensor readings, keeping the unit whisper-quiet when air is clean and ramping up when cooking smoke or pet dander spike.
