- Indoor Air Quality: Sick building syndrome (SBS) affects 1-in-4 people in Japan due to volatile organic compound (VOC) exposure. A study of junior high school students reported that 45.4% suffered from mucosal symptoms (eye/nose irritation) and 38.9% experienced general symptoms like fatigue.
- CO2 Levels: In Tokyo-area secondary schools, roughly 58% of classrooms were found to be “unsuitable” (exceeding 1,000 ppm) during winter.
- Humidity: In summer, humidity often exceeds 70%–80% in non-air-conditioned spaces, creating a high mould risk. In winter, in centrally heated Hokkaido, it can drop below 30%, but in other regions, unheated rooms can reach over 80% RH at night when temperatures drop.
- Temperature: National surveys show average living room temperatures of 16.8°C, but bedrooms often drop as low as 12.8°C. There is a significant regional gap; homes in Hokkaido average 19.8°C, while those in Kagawa average only 13.1°C.
- Particulate Matter: Japanese residential studies show cooking increases PM2.5 by 2 to 96 times the background value, with concentrations frequently ranging between 3 and 140 µg/m³. Most particles emitted during cooking in Japanese homes are in the PM1 range (0.3–1.0μm).
EDUCAIR makes tracking indoor air quality simple, alerting occupants to arising issues and providing guidance on how to rectify them.
EDUCAIR records:
- Four-point Averaged Temperature (°C) & Absolute Humidity (g/kg)
- NDIR CO2 Measurement (ppm)
- Particulate Matter in PM1/PM2.5/PM4/PM10 Levels
- VOCs Measured in Both Wide & Narrow Band, Giving Early Warning Detection
EDUCAIR records the data internally to spot and plot trends
