Maintenance of correct indoor air quality with energy-efficient

Indoor air quality

Indoor air quality is one of the EPA’s top five environmental risks to public health. Indoor air pollution is two to five times worse (sometimes a 100x worse) than the air outdoors. Nearly 2 million people die prematurely from illness attributable to indoor air pollution from household solid fuel use. Well, these are not just facts but an introspect of your daily livelihood. When we think about pollutants, we often think about those found outside whether in the air, the ground, or in waterways. Indoor air quality, though, is just as vital to our everyday lives and health, and the pollutants found inside should concern us just as much, if not more.

According to the Environmental Protection Agency (EPA), each year, more than 7 million people across the globe die because of exposure to indoor and outdoor air pollution. Of those 7 million premature deaths, 3.8 million are caused by exposure to indoor air pollution.

Clean air through a house fresh air system can prevent many environmental health hazards such as asthma, which, according to the U.S. Environmental Protection Agency, affects 25 million people in a given year, including 7 million children. Asthma accounts for nearly 17 million physician office and hospital visits.

The Effects

According to WHO, 4.3 million people a year die from the exposure to household air pollution. The effects of indoor air pollutants range from short-term effects – eye and throat irritation – to long-term effects – respiratory disease and cancer. Exposure to high levels of some pollutants, such as carbon monoxide, can even result in immediate death. Also, some indoor pollutants can magnify the effects of other indoor pollutants. Based on cancer risk alone, federal scientists have ranked indoor air pollution as one of the most important environmental problems

Main Causes of Indoor Air Pollution

  1. Asbestos is the leading cause of indoor air pollution. They are most commonly found in coatings, paints, building materials, and ceiling and floor tiles.
  2.  Formaldehyde is another leading cause of indoor air pollution
  3.  Radon which can be found underneath your home in various types of bedrock and other building materials, can also be a cause of indoor air pollution.
  4. Tobacco smoke that comes from outdoor and indoor areas can also be an indoor air pollutant.
  5. Contaminants such as mildew, mold, bacteria, dust mites, as well as animal dander, can come into the home and make you sick.
  6. Objects such as wood stoves, space heaters, and fireplaces, all put out carbon monoxide as well as nitrogen dioxide.
  7. Household products such as varnishes, paints, and certain cleaning products can also emit pollution

The likelihood of immediate reactions to indoor air pollutants depends on several factors including age and pre existing medical conditions. In some cases, whether a person reacts to a pollutant depends on individual sensitivity, which varies tremendously from person to person. Some people can become sensitized to biological or chemical pollutants after repeated or high level exposures.


It is not possible for us humans to detect changes in air quality. We can’t for example detect when certain air pollutants reach high concentrations. We therefore can’t expect an occupant to assess what ventilation level is necessary in order to achieve a healthy indoor climate.

That is why it is important that the ventilation level should be adjusted automatically according to the most effective ventilation needs. By means of intelligent sensors, the ventilation level responds to the various situations at any moment of the day. If the air in the room is of a good quality, then the extraction flow rate in that room is lowered. This automatic adjustment will result in energy savings of 30 up to 50%.

The smart and quietest solution for healthy indoor air via HEALTHBOX® 3.0

Healthbox® 3.0 forms the heart of the energy-efficient ventilation concept C+, whereby fresh air is supplied into the dry rooms via window vents and the polluted air is extracted mechanically via Healthbox® 3.0.

The advantages of the energy-efficient ventilation concept C+ are numerous. It is the healthiest choice because the supply of fresh air is done directly via (window) vents. Since there are no filters, the system is very maintance-friendly.

The discrete window vent Invisivent stands for a high energetic, acoustic and thermal comfort.

The integrated demand-controlled ventilation control in Healthbox 3.0 intelligently adjusts the ventilation level per room automatically (24/7), based on the measured indoor air quality. This ensures optimal comfort and maximum energy savings.

Despite its compact size, Healthbox 3.0 performs impressively. Both the energy-efficient EC fan with a large impeller and its high-tech active variable pressure control are the basis for extremely silent and energy-efficient operation. Thanks to the ‘extra silent setting’ even occupants with highly sensitive hearing can be guaranteed a quiet and peaceful night.


The integrated SmartConnect establishes the link between Healthbox 3.0 and the digital world. Healthbox 3.0 can provide interaction with the user in this way (via the app) and with other smart devices in the Smarthome (in order to experience enhanced overall comfort). Your internet connection keeps Healthbox 3.0 automatically up to date with new features.

The free Healthbox 3.0 app* gives the user a clear view on the air quality and the ventilation level in the home. Moreover, it is possible to make fully customised adjustments to the ventilation level of each room in the house, not only using the various profiles but also manually.

Digitisation of paperwork

The Renson Lio web portal is the tool for managing your installations, which is of benefit for both smaller installers and (large) installation companies. Link all related documents and choose the suitable installer(s) for a project.

The proper functioning of these products largely depends on their correct installation and adjustment by the installer. That is why they support you with a thorough technical training. Their experienced trainers are ready to show you the ropes and explain how to install everything correctly. Only in that way we come to properly working and reliable ventilation systems that provide the best possible indoor climate and meet all technical and quality requirements.
