A number on a screen, and what it does and does not tell you · review
Lists PM1.0, PM2.5, PM10, TVOC, HCHO, temperature and humidity, sampling every 1.5 seconds.
Where this leaves you The same bullets as the AQItech on this shelf at the same price, with one difference: this listing's parameter list does not include CO2. On a monitor sold for ventilation decisions, that is the parameter that matters most.
Two monitors on this shelf carry the same five bullets. One of them names CO2 among the parameters; this one does not.
CO2 is the reading that tells you a closed bedroom needs airing, which is the use case both listings lead with. If the sensor is present, the listing has left it out; if it is absent, the listing is accurate and the identical one next to it is not. Either way, the page you are reading cannot resolve it — and the one that names CO2 costs the same.
Seven parameters, by this listing’s own count in the same breath as the sixteen. The number on the box is a feature total, and only one monitor on this shelf shows the working.

The listing does not say it does. Its parameter bullet names PM1.0, PM2.5, PM10, TVOC, HCHO, temperature and humidity — and the AQItech on this shelf, whose bullet is otherwise word for word the same, adds CO2 to that list. This page reports what is published and will not assume the sensor is there.
Not sixteen measurements: this listing names seven. The Sainlogic on this shelf publishes the arithmetic — nine parameters plus seven alerts — and it is the only monitor here that does.
For particulates, yes: PM2.5 changes in seconds when you cook or open a window, and a slow refresh hides it. Three monitors on this shelf publish 1.5 to 2 seconds and one publishes 3.
