Coway Airmega Mighty
“You could call the Coway Mighty the Toyota of air purifiers because I’ve been running this thing nonstop for two years, and it hasn’t stuttered or failed once. That’s impressive for any machine — let alone one that’s on 24/7.”
Coway Airmega Mighty
"Perfect for bedrooms, playrooms, and living rooms, the Mighty is one of the best-performing, most durable, and most economical purifiers we’ve tested."
Coway Airmega 350
"...The Airmega 350 moves a lot of air, and you’ll notice it quickly. CADR Give it a bit of time, and the room feels cleaner and less stuffy. Cooking smells fade fast, dust doesn’t hang around as much, and yes, it’ll even take the edge off whatever biological warfare a dog brings into the room."
