HowsYourAir has been on the hunt for a less expensive and still reliable CO2 monitor for nearly a year. The data now suggest that the Qingping (QP) monitors fit the bill. BONUS: These also measure PM2.5 & PM10! Pretty impressive.

      See below for link to a comprehensive review and to a US-based company offering the monitors. This page focuses on the LITE model.

Here's a comprehensive review of the Qingping (QP) Air Monitor Lite* from Breath Safe Air (@safe_breathe@twitter.com)

​"Best All-In-One Carbon Dioxide Monitor"

​

Components:

  • CO2 sensor: SenseAir (S8) or Sensirion

  • PM sensor: GrandWay

  • Temperature & relative humidity sensor: Sensirion

 

"[M]y biggest complaint is needing to swipe five times to see all the data provided by the monitor."

​So much data, so many swipes.

Not a bad problem to have in an affordable CO2 monitor with PM sensor, too!

 

*Note: "Smart Air" is SmarterHEPA in the US. HowsYourAir is just not an Amazon fan, though the unit is $3 less there.
