The brand’s newest medium-to-large room cost-effective air purifier is designed to deliver the ultimate sleep environment while using barely any energy.

LOS ANGELES, Aug. 27, 2026 /PRNewswire/ — Today, Coway, the leading wellness tech company, introduced the Airmega Halo, a next-generation cylindrical air purifier engineered to deliver whole-room air purification for medium to large rooms at an accessible price point, with an entire experience built around a better night’s sleep.  

Designed with a 360° air intake structure, the Airmega Halo rapidly draws in polluted air from every angle to maximize purification efficiency without spatial constraints, and its ENERGY STAR 3.0 certification pairs that power with strong energy efficiency. At a time when wildfire smoke and seasonal allergens are driving greater attention to indoor air quality, the Halo expands Coway’s Airmega line with a new mid-size option built for medium to large rooms, sitting between the compact Airmega 50 and 100 and the high-capacity 350 and 450. It captures 99.97% of nano-sized particles down to 0.3 microns, effectively removing allergens, bacteria, mold, and viruses.

The Airmega Halo delivers massive, whisper-quiet airflow, capable of cleaning up to 1,898 square feet in one hour (based on one air change per hour). In Sleep Mode, an intelligent Night Sensor detects darkness and automatically dims the display and drops to an industry-leading 17.8 dB(A) so you can sleep undisturbed.

With 38W max power consumption, it is ENERGY STAR 3.0 certified, meeting strict energy-efficiency standards designed to reduce electricity use and help lower operating costs. In Smart Mode, it automatically shifts into Eco Mode when the air is clean, then returns to full power when needed, helping maintain clean air without wasting energy. The 3-in-1 filters (Pre-Filter, HEPA, deodorization carbon) have a 1-year lifespan, meaning lower maintenance costs with regular cleaning.

Key features include:

• Smart mode: Set it and let the purifier adjust automatically. Smart mode responds to changing conditions by switching between Sleep and Eco modes and adjusting airflow speed as needed.
  • Auto Sleep mode: Automatically dims the display and drops to an industry-leading 17.8 dB(A), quieter than a whisper, the moment the room goes dark. Set it once to your preference, a soft night light or a fully dark display, and it handles the rest.
• MegaScan^TM Particle Sensor: Continuously monitors the air in real time, detecting smoke, fine dust, and allergens down to PM2.5.
• HyperVortex^TM filtration system: Coway’s aerodynamic fan and duct design, inspired by eagle wings and golf ball dimples, boosts airflow and purification power while keeping the Halo remarkably quiet.

Design: The Halo’s design brings its name to life. A soft blue ambient light glows from a recessed ring inside the top display, creating a halo effect without glare. The compact cylindrical body features a 360° pinhole air intake at its base, paired with a clean white finish and silver rim accent, while an intuitive top touch panel keeps controls and air quality status clearly visible. The Airmega Halo was created with aesthetics and convenience in mind, designed for any room in your home or office space. Key convenience features include:

• 4-color LED air quality indicator: Provides clear visibility of current air quality levels.
• Timer: Schedule operation from 1, 4, or 8 hours to fit your routine.
• Control panel lock: To prevent kids and pets from changing settings.
• Air flow control: Smart (Auto airflow 1-3, Sleep, Eco), Turbo modes
• Easy-grip handle: For easy portability around the home.
• Night light: Provides gentle illumination that won’t disrupt rest.
• Modern and intuitive touchscreen panel: Displays real-time AQI and provides intuitive control.

The Airmega Halo is available now in White for $229.99 at Cowaymega.com and Amazon. To learn more about Coway, visit Cowaymega.com.
