With certain exceptions, air purifiers aren't especially smart or powerful. They'll remove some of the nastiness, but it's anyone's guess as to how much there actually is. Sprimo thinks it can change that: it's crowdfunding a purifier that's not only more effective than conventional rivals (reportedly up to 50 times more efficient), but designed from the ground up with intelligence in mind. It'll tell you the basic contents of the air and give you a quality rating to give you a sense how clean that air really is. The device will also give you a sense of what filters to use (say, one geared towards pollen) and tell you when you're likely to need a replacement.
