What is detected by the sensors in Blueair Classic i-series (280i/90i, 480i/90i, 580i/90i, 680i/90i)?

Particulate matters (PM2,5)

PM2.5 are air pollutants with a diameter of 2.5 microns (micrometres/µm) or less. PM2.5 is also known as 'fine particulate matter’.

The most common PM2.5 sources are car traffic, industrial plants, metal processing, cleaning fluids, beauty products, candles, cooking and smoking.

Total Volatile Organic Compounds (TVOCs)

The sensors integrated in the Blueair Classic i-series air purifiers measure the total level of VOCs in the air (tVOCs). TVOCs is a grouping of a wide range of organic chemical compounds, including both human-made and naturally occurring chemical compounds.

The most common VOC sources are building materials (paint and varnish), furniture, printers, cleaning products, air fresheners, laundry detergent, glue, paint, perfume, repellent and scented candles.

Temperature and humidity

The sensors in the Blueair Classic i-series air purifiers measure temperature and humidity levels. Understanding the evolution of temperature and humidity levels in your home will help you detect water stagnation, water damage, humid surfaces and warm environments, which encourage the growth of mold, bacteria and allergens (such as dust mites).
