What Air Pro senses in the air
There are two sensors within Air Pro: a particulate sensor and a chemical sensor.
The chemical sensor in Air Pro is designed to reversibly react with specific chemicals in the air, giving you a window into the composition of the air in the room it’s in, which can help to maintain air quality. The chemical sensor contains elements that react with the atmosphere, so Air Pro can tell when water vapor, VOCs, or carbon dioxide levels change.
The chemical sensor can detect these three dimensions of air quality and let you know their approximate concentration in the air. There is more to air pollution than the particles detected by the particle sensor or these three readings. While Air Pro will not detect other pollutants like ozone, the PECO technology at the core of the purifier is still working to destroy them.
The Chemical Sensor
The chemical sensor is actually three sensors in one, each able to measure a different aspect of air quality.
- VOCs: Volatile Organic Compounds, or VOCs, are a very wide category of carbon-based airborne chemicals. Their sources include industrially produced products such as adhesives, paint, cleaning chemicals, air fresheners, and building materials. They also come from more innocuous sources in small amounts such as alcoholic drinks and essential oils.
- CO2: Carbon dioxide, or CO2, is a byproduct of living things and the burning of fuels. Its primary indoor source in occupied spaces is typically human respiration.
- RH: Relative humidity, or RH%, is a measure of how much water vapor is present in the air. Humidity has many sources, including the environment, leaking pipes, or just indoor use of hot water.
