Indoor air quality as the quality of air within and around buildings and structures, particularly as it relates to the health and comfort of the building’s occupants.
Poor air quality can lead to health effects that are not always experienced directly after exposure causing some side effects to show up years later.
Especially nowadays air quality is extremely important to the health. HVLS fans moves large volumes of the air same time don’t spread up allergens and irritating dust. Helps eliminate stagnant air.
HVLS can increase airflow supply within a building to prevent spreading viruses in the building.
Air pollution – be it indoors or outdoors – is a major environmental health concern as it can lead to serious health effects, such as respiratory diseases, including asthma and lung cancer.
Much progress has been made in Europe in improving outdoor air quality and limit values have been set for several pollutants. However, indoor air quality also requires attention because this is where we spend most of our time.
Assessing the health risks of indoor air pollution is very difficult as indoor air may contain over 900 chemicals, particles and biological materials with potential health effects. Factors like ventilation, cleaning conditions, building characteristics, products used in households, cultural habits, climate and outdoor environment all influence indoor air quality. Therefore, large variations can be expected across the EU.
The Scientific Committee on Health and Environmental Risks (SCHER) is one of three independent non-food scientific committees that advise the European Commission on matters of consumer safety, public health and the environment.
The European Commission Scientific Committee on Health and Environmental Risks (SCHER) concludes:
- The principles used in the EU for risk assessment of chemicals should also be applied to indoor air.
- More research and data are needed, particularly on particles and microbes, volatile organic compounds from consumer products, building dampness, levels of exposure, and effects on vulnerable populations.
- Gaps in knowledge should be addressed by European-wide multidisciplinary research.
- Indoor air pollutants of particular concern are carbon monoxide, formaldehyde, benzene, nitrogen oxides, naphthalene, environmental tobacco smoke, radon, lead and organophosphate pesticides.
The SCHER also recommends:
- Data on combined effects of indoor pollutants should be gathered.
- All possible routes of exposure should be considered.
- Health-based guideline values for key pollutants and other practical guidance should be developed.
- The impact of indoor exposure should be considered when evaluating the health effects of outdoor air pollution.
- All relevant sources known to contribute to indoor air pollution should be evaluated.
