Speck was featured on NPR as a device available through Pittsburgh's Carnegie Library system to reduce air quality in homes.
From the middle of the article: "Horchner's family is amused by his vigilance, but now his daughter, Christine, and wife, Nadine, are gathered around the kitchen table to see what the Speck monitor will reveal. Horchner guesses an optimistic 10 or lower. Nadine predicts the room will yield a reading of 30."
