Final Verdict
For large rooms and value, the Coway Airmega 400 wins clearly: it purifies nearly double the square footage, runs at 22 dB (you can sleep through it), and costs $300 less. The Dyson TP07 wins if you want the purifier to double as your room’s fan — the oscillating airflow and premium Dyson Link app data (10 pollutant types monitored) justify the price if you’re replacing both a purifier and a fan. For most rooms: Coway. For design-forward dual-use: Dyson.
