Would you consider my purifier's readings reasonably accurate?
Comparing my Philips AC3220 with the IKEA Vindstyrka and it seems to underreport by 3x at low concentrations.
Is this sort of gap acceptable?
At somewhat higher concentrations it generally shows pretty much the same values, but if I set it on auto mode, readings drop and cause this large gap.
On very high concentrations though, the opposite happens- my purifier could be showing as much 300+ while the IKEA device shows 85.
What should I make of this?
