This is how you keep your indoor climate unaffected

We spend a lot of our life indoors. Anyone who assumes that they are protected from air pollutants is wrong. Harmful substances can also affect our health in homes or work rooms. The indoor air is polluted by a mixture of pollutants.

Volatile organic compounds

Volatile organic compounds (VOC) are largely released indoors through the evaporation of solvents, e.g. in paints, varnishes and adhesives. Sources are paints, floor coverings, adhesives, carpet backings and home textiles. Fragrance oils also give off VOCs.

Most of the time, the VOC concentrations in apartments are rather low. Concentrations that cause adverse health effects can, however, occur immediately after construction work or major renovation measures, especially if harmful products are used. VOCs in low concentrations can cause unspecific effects on the body, including irritation of the mucous membranes of the eyes, nose and respiratory tract, headache, tiredness, poor concentration or nausea.

Formaldehyde is very irritating

Formaldehyde is a colorless, pungent smelling gas. It is mainly used in the manufacture of synthetic resins. These are often contained in building products or interior materials, e.g. chipboard, adhesives or insulating foams. But formaldehyde is also released with tobacco smoke.

Formaldehyde has a strong irritant effect on the mucous membranes of the upper respiratory tract and the eyes. The possible effects are similar to those of the VOC. Prolonged exposure can trigger bronchitis and asthma. In higher concentrations, formaldehyde increases the risk of cancer (e.g. blood cancer and cancer of the upper respiratory tract).

Smoking causes fine dust particles

Burning tobacco produces a wide range of toxic air pollutants, including numerous carcinogenic substances. These poisons are not only inhaled by smokers, but also represent a nuisance for others via the indoor air or as fine dust. The smallest fine dust particles from the combustion of tobacco are deposited on walls, ceilings and objects and can repeatedly be caused by a draft be whirled up and pollute the room air.

Tips for clean indoor air

Here's how you can avoid air pollutants in your home:

  • Give preference to eco-labeled paints, varnishes and adhesives
  • Do not use "air fresheners" (eg fragrance lamps, fragrance oils, scented candles).
  • New or renovated apartments: Ventilate well and often, especially in the first few weeks.
  • The extensive use of chipboard should be avoided or only high-quality panels should be used.
  • Do not use acid-hardening parquet sealants in living areas.
  • Do not smoke.
