A number on a screen, and what it does and does not tell you · review
Measures PM1.0, PM2.5, PM10, CO2, TVOC, HCHO, temperature and humidity, sampling every 1.5 seconds.
Where this leaves you A 16-in-1 monitor whose own bullet lists eight parameters and calls them seven. Its title is word for word that of two other monitors on this shelf, one of which costs sixty dollars less.
All three figures come from this one listing. The eight are named, the seven is asserted in the same sentence, and the sixteen is in the title.
The Sainlogic on this shelf is the only monitor that reconciles it: nine parameters plus seven alert thresholds. On that reading, “16-in-1” describes the feature list and not the sensor count — and it is worth knowing before paying for a bigger number.
AirWhisper, MORPTRA and this one share the same product title to the word. Two of the three share the same five bullets. The prices read 79.99, 139.99 and 139.99.
The one published difference at the cheap end is that the AirWhisper says it has no alarms. Whether that is worth sixty dollars is the only question this shelf poses here.

Eight, by its own bullet, which then calls them "7 core ambient indicators". The only monitor on this shelf that explains the number is the Sainlogic: it publishes "9 Parameters and 7 Alerts", which makes sixteen. Read 16-in-1 as a marketing count, not a parameter count.
This listing does not say. One monitor on this shelf publishes ±15 µg/m³ for PM2.5, which is a large tolerance at household levels — and it is the only PM2.5 figure anywhere here. On the other five, including this one, the accuracy is unknown.
Nothing in either listing explains it. The AirWhisper here carries the same title and was read at 79.99 dollars, with the difference that its listing states it has no alert or alarm functions. This one has an audio prompt.
