I know, I know. $300 is a lot to spend on an air purifier. But come on, look at this thing. With no visible blades, you could put your arm straight through the Dyson Cool Link. It also has a true HEPA filtration system (those don’t come cheap, even from other manufacturers), and with built-in Wi-Fi, you can even control it and monitor your room’s air quality from your phone, even if you’re away from home.

$300 is an unprecedented price, and in fact, Amazon’s currently selling refurbs for $29 more than the cost of a new one.
