Ned Posted February 2, 2019 Share Posted February 2, 2019 Where do they sell pm2.5 sensors in CM? I've seen them on Lazarda etc but would prefer to check out the product first. Thanks Link to comment Share on other sites More sharing options...
madmen Posted February 2, 2019 Share Posted February 2, 2019 Air purifiers with built in sensors are not that much different in price approx 3500 baht for machine assuming you don't have a machine already Link to comment Share on other sites More sharing options...

Loaded Posted February 2, 2019 Share Posted February 2, 2019 40m2 HEPA filter plus PMQ sensor and an ION button for just under 7k THB in Index on the superhighway. 26m2 HEPA filter but no sensor was just under 4k THB. Siam TV and Big C only had 15k THB Japanese stuff. Link to comment Share on other sites More sharing options...

chingmai331 Posted February 2, 2019 Share Posted February 2, 2019 I checked that airvisual site for CM. Gotta wonder about the accuracy of the data, esp when the report says 'data provided by 11 contributors'. Which of course suggests that this in NOT data but personal observation and absolute bias. But CM rated better than UlanBattor so i'm good. Link to comment Share on other sites More sharing options...

AirVisual is an actual monitor that is installed and monitors the air particles 24/7. That data is shown on the device’s monitor and also provides an app that can display the data. Additionally, users can register their devices with AirVisual to be a data provider, which basically uploads the data to their servers and it will display on the internet hourly for others to see. Those 11 contributors are providing valuable data to the rest of us and I’d say it’s pretty accurate. Link to comment Share on other sites More sharing options...
sfokevin Posted February 3, 2019 Share Posted February 3, 2019 I would be more likely to trust AirVisuals data than some Government controlled measures... Link to comment Share on other sites More sharing options...

There are different standards published by governments, NGOs etc. A lot of what is reported depends on what standards are used. Link to comment Share on other sites More sharing options...
