It’s one hell of a smart air purifier: It has a continuously operating air quality indicator that senses the presence of air particles and adjusts the fan speed accordingly to keep the air nice and clean. It’s perfect for your kid’s room, or your living room. Its filter lasts roughly 12 months, which is nice for those of us not rolling in cash. It has a one hour, four hour, and eight hour timer. There’s an indicator that will let you know when it’s time to change the filter. In fact, Wirecutter had this to say about it: “The Coway Mighty is the right size for master bedrooms, playrooms, and living rooms—and it’s one of the best-performing, most durable, and most economical purifiers we’ve ever tested.” Sure, we love the Dyson. Everyone loves the Dyson. Our wallets do not love the Dyson. This is a stellar alternative. Every product on Fatherly is independently selected by our editors, writers, and experts.
