Air Quality Monitor

You can live without food for a month, without water for a week and without air for five minutes. It is important to be aware of the air we breathe.

The JACOB JENSEN Air Quality Monitor is a user-friendly product that measures and displays indoor air quality, humidity and temperature, providing you with an essential overview of the indoor climate in your home.


Major sources of PM2.5 particles include: tobacco smoke, cooking (e.g., frying, sautéing, and broiling), burning candles or oil lamps, fireplaces, cleaning products as well as infiltration from outdoor sources.

Particles in the PM2.5 size range are able to travel deeply into the respiratory tract, reaching the lungs. Exposure to fine particles can cause short-term health effects such as eye, nose, throat and lung irritation, coughing, sneezing, runny nose and shortness of breath. Long-term health effects include allergies, cancer, asthma, infertility and even birth defects.
PM2.5 particles are one the of deadliest airborne pollutants.

The JACOB JENSEN Air Quality Monitor measures PM2.5 particles. It converts the number of particles into AQI (Air quality index).


We spend around 90 percent of our time indoors, exposing ourselves to various airborne pollutants. Major sources of these pollutants can be divided into two main groups:

VOCs - (Volatile organic compounds) are organic chemicals with high vapour pressure. Most scents or odours consist of VOCs.
CO - (Carbon monoxide) is a gas and is found in air. CO’s are produced by tobacco smoke, candles, fireplaces, clothes dryers, gas stoves and ovens etc.
NO² - (Nitrogen dioxide) is a ‘nasty-smelling’ gas. The major source of nitrogen dioxide is the burning of fossil fuels, i.e. coal, oil and gas.

PM10 - Particles with a diameter of 10 micrometers or less. A human hair typically has a diameter of 70 micrometers, while a grain of sand measures about 90 micrometers.
PM2.5 - Also known as fine particles refers to tiny particles in the air that are two and one half microns or less in width.
