Since the weather channel is only correct about 25% of the time, take air monitoring into your own hands with the Netatmo Weather Station ($179). Working in conjunction with the free downloadable Netatmo app, the Netatmo Weather Station consists of two sensors that accurately monitor and record air-related stuff such as the CO2 concentration, air quality, indoor temperature, humidity, and even noise pollution—And then wirelessly transmits the findings to your iPhone in the form of various lists and graphs.
