Hi @Garry_Harris

PurpleAir sensors have been evaluated to be highly precise by the South Coast AQMD’s AQ-SPEC sensor evaluation program. You can find the results of those evaluations here: https://www.aqmd.gov/aq-spec/evaluations/criteria-pollutants/summary-pm

I also recognize that you may be looking for unbiased opinions. So I’ll let some others jump in here.
