Coway Airmega 400

The Coway Airmega 400 is a powerhouse air purifier designed for large spaces, covering up to 1,560 square feet with a CADR of 340 CFM. Its dual Max2 filter system combines pre-filters, deodorization filters, and True HEPA filters to capture 99.97% of particles, including allergens, smoke, and odors. The smart auto mode adjusts fan speed based on real-time air quality, indicated by a color-changing LED ring, while Eco mode shuts off the fan when air is clean, saving energy. At 22 dB on low settings, it's quiet enough for continuous use, and the modern design blends seamlessly into homes. The 5-year warranty ensures long-term reliability, though the dual-filter system means higher replacement costs. For open-concept homes or large rooms, the Airmega 400 offers unmatched performance and durability.
