Questions
How do I choose a purifier size?
Match the suggested room size to the floor area of the room. For open-plan spaces, choose the HN-1200 or use two units.
What does the monitor measure?
The NexusSense 7-in-1 reads CO2, PM2.5, PM10, formaldehyde (HCHO), TVOC, temperature and humidity.
Do you sell sensor chips?
Not yet. Sensor modules are a planned line; you can register interest on the Sensor modules page.
Why is the CO2 monitor sold in packs?
It is a school pack: 12 monitors for classrooms, offices and rental units, priced per pack. The product page shows the per-unit price.
