NEA's readings cover five regions. A home monitor tells you what your child is actually breathing in their room, so you know whether closing windows and running the purifier is working.
How home PM2.5 monitors work
- Most use a small laser sensor that counts fine particles and estimates PM2.5 in µg/m³, the same unit as NEA's 1-hour PM2.5 reading.
- Consumer sensors are less precise than NEA's official stations and can read high in humid air. Use them for trends (is the room getting better?) rather than exact numbers.
- Place it at your child's breathing height, away from the purifier outlet, kitchen and open windows.
- Compare with NEA's bands: 0–55 Normal, 56–150 Elevated, 151–250 High, 251+ Very High. Indoors with windows shut and a purifier on, you want it well inside Band 1.
- Some monitors, such as IQAir's AirVisual range, can share readings to public maps like IQAir's Singapore map.
