What is indoor air quality or IAQ?

General questions about Sentera devices
In the developed world, we spend 90% of our time indoors. Research shows that key pollutants are up to five times more concentrated inside than outside. According to WHO, around 3.8 million people a year die from the exposure to household air pollution. This indoor air pollution comes from a variety of sources, and includes a wide range of gases, chemicals and other substances.

When we make our homes more airtight, we risk to that VOC levels will start to build up. VOCs or Volatile organic compounds in indoor environments evaporate from substances such as cleaning products, adhesives, paints, new carpets, copiers and printers to building materials and furnishings. VOCs are also emitted from humans and animals in their breath, sweat and directly from their skin. VOCs are known to cause eye, nose and throat irritations, headache, drowsiness, dizziness, nausea, difficulty concentrating and fatigue.

Closing doors and windows keeps the heat inside, but it also leads to a more humid environment, especially as we dry clothes on radiators or tumble dryers, rather than outdoors. Higher humidity causes mould, moisture and condensation, which all impact our health negatively.

It is our mission to optimise your comfort, indoor air quality and to contribute to your health in a positive way and therefore, Sentera developed a complete range of HVAC transmitters – the eyes of a smart ventilation system – to monitor and optimise your indoor air quality. Based on these measurements, the fan speed can be optimised to improve indoor air quality and realise energy savings.

What’s in it for you?
Well, these are the short-term benefits of a good indoor air quality:
- Better breathing
- Better sleep
- Elimination of allergens
- Reduced odours
- Balanced humidity
- Reduced energy costs
