I quite enjoy Acurite’s indoor sensor. I have used it outdoors and am quite pleased with its response.
I wonder whether IKEA’s newly available in Australia USB PM2.5 monitor might be worth testing?
At just $USD10 it may be similar to that included in some air purifiers.
Colour coded:
85
My nearest EPA station does occasionally measure above 36 for PM2.5 – but belatedly and being some miles distant taking this monitor (connected to a power bank) outside has proved unsuccessful in registering other than clean air (<36).
If reasonably accurate might a reading below maximum (“36 – 85”, ‘<36’) be good enough to indicate that an air purifier was clearing high pollution?
Airvisual Pro only in the 10th place? Yet they according to their paper, the 2nd gen seemed pretty accurate?? I don’t understand this..
How come that the Airvisual dropped in ranking? I bought it in the beginning of 2020 after having read it’s pretty accurate, but now I understand it’s not that accurate anymore.
Has any org done similar testing for CO2 monitors? I looked at the AQMD gaseous test results table at https://www.aqmd.gov/aq-spec/evaluations/summary-gas, but CO2 was not one of the target gases.
