Airmega Smart Air Purifier
It's certainly not the first connected gadget to tell you when your air quality is poor, but the Airmega Smart Air Purifier can also do something about it. It as a bright LED ring on the front to let you know the current air status, an app for when you want more information, a smart mode that automatically controls the fan speed, and a MAX2 Filter that removes up to 99.97% of allergen, molds, fine dust, VOCs, and odors. Available graphite or white and in multiple sizes to match different home decors and sizes.
