Digital Monitor
The digital monitor on the front side of the air purifier CA-509Pro Smart indicates
automatically and exactly current air quality by measuring the level of Particle measurement
PM2.5, indoor humidity and temperature.
Green - Good: 0-80ug/m³ Blue - Average: 80-150ug/m³ Red - Bad: 150 ug/m³ or more
Particulate matter of 10um (PM10) and smaller 2,5 um (PM2.5) can get into the lungs and
belongs to the top 10 threats for human health. These small particles develop through typical
indoor processes such as cooking, baking, frying, smoking, as well as heating or are also
transported in big quantities into indoor air because of transportation, industry, construction,
biological material (pollen, bacteria, mites, and viruses), imported particles from other regains
such as (airplane) exhaust gases and volcano eruptions.
Allergens such as pollen and dust cause serious and long-term health threats to millions
of persons each spring: the numbers are increasing constantly.

Important aspects for effective air purification: relative humidity between 45 - 60% and room
temperature of about 20 - 23 °C
