What are VOCs?

Volatile organic compounds (VOCs) are gaseous substances that off-gas from various materials and products. They can affect air quality and cause health problems. VOCs accumulate especially indoors, since ventilation is often insufficient to fully disperse them.

The most common VOCs indoors

Here are some of the most widespread VOCs, their main sources, and possible effects:

1. Formaldehyde VOC
   
   • Sources: furniture, particleboard, paints, varnishes, adhesives, textiles
   • Risks: respiratory irritation, eye irritation, possible carcinogenic effect
2. Benzene
   
   • Sources: tobacco smoke, paints, solvents, vehicle exhaust (also from outdoors)
   • Risks: headaches, dizziness, long-term increased cancer risk
3. Toluene
   
   • Sources: paints, adhesives, varnishes, printing inks
   • Risks: dizziness, headaches, respiratory irritation
4. Xylene
   
   • Sources: varnishes, paints, solvents, plastics
   • Risks: respiratory irritation, headaches, dizziness
5. Acetone
   
   • Sources: cosmetics, nail polish remover, cleaning products
   • Risks: eye and respiratory irritation, headaches
6. Styrene
   
   • Sources: plastic products, insulation materials, carpet adhesives
   • Risks: nervous system impairment, irritation
7. Terpenes (limonene, pinene)
   
   • Sources: fragrances, essential oils, cleaning products
   • Risks: can react with ozone and form harmful byproducts
8. Trichlorethylene
   
   • Sources: stain removers, varnishes, adhesives
   • Risks: liver and kidney damage, nervous system impairment
9. Tetrachlorethylene
   
   • Sources: dry cleaning, adhesives, paints
   • Risks: nerve and organ damage, suspected carcinogen
10. Naphthalene
    • Sources: mothballs, wood preservatives, exhaust fumes
    • Risks: respiratory irritation, possible cancer risk
11. ‍Ethyl acetate
    • Sources: adhesives, nail polish remover, varnishes
    • Risks: eye and respiratory irritation, headaches

1. Methanol
   • Sources: solvents, paints, printing inks
   • Risks: nervous system damage, headaches, nausea

1. Chloroform‍
   • Sources: tap water (through evaporation), disinfectants
   • Risks: liver and kidney damage, possible carcinogenic effect

1. Cyclohexane
   • Sources: adhesives, paints, varnishes
   • Risks: headaches, respiratory irritation, dizziness

1. 1,3-Butadiene
   • Sources: tobacco smoke, exhaust fumes, plastics production
   • Risks: carcinogenic potential, immune system damage

Formaldehyde VOC: A critical look at a widespread air pollutant

Formaldehyde VOC is a common member of the group of volatile organic compounds (VOCs) found indoors. It's a colorless, pungent-smelling gas that's released from a wide variety of sources, including building materials, furniture, textiles, and some household products.

As a VOC, formaldehyde is especially concerning, since it can cause health problems even at low concentrations, such as eye, nose, and throat irritation. Long-term exposure can lead to more serious health problems, including respiratory diseases and an increased risk of cancer.

To reduce exposure to formaldehyde indoors, it's important to look for low-emission products and ventilate regularly. Installing air purifiers specifically designed to remove VOCs can also help improve air quality and protect residents' health.

Methanol VOC: An often overlooked indoor pollutant

Methanol VOC belongs to the group of volatile organic compounds (VOCs) and is found in many everyday items and industrial applications. It's frequently used in cleaning products, antifreeze, and as a solvent in paints and varnishes. Due to its high volatility, methanol can easily enter indoor air and thus contribute to indoor air pollution.

The health effects of methanol exposure can range from mild symptoms like headaches and nausea to more serious effects like vision disturbances and neurological problems, especially with high or long-term exposure.

To reduce methanol concentrations indoors, methanol-free alternatives should be preferred and well-ventilated rooms should be created. Using air purifiers specifically designed to remove VOCs can also help improve air quality and minimize health risks.

How can you reduce VOC exposure?

• Ventilate regularly – Daily brief, intense airing (Stoßlüften) helps lower the concentration of VOCs.
• Choose low-pollutant products – Look for eco-friendly, low-VOC paints, varnishes, furniture, and cleaning products.
• Use air-purifying plants – Some plants like ivy, snake plant, or peace lily can help filter VOCs from the air.
• Control room temperature and humidity – High temperatures and humidity promote the release of VOCs.
• Store chemicals properly – Solvents, paints, and cleaning products should be kept in well-ventilated rooms or outside living spaces.

The air-Q: Support for measuring VOCs

The air-Q is a smart air analyzer that helps monitor the quality of indoor air. The air quality monitor measures the concentration of various pollutants, including VOCs, and provides real-time data on air pollution. By using the air-Q, you can take targeted measures to improve air quality in your living and working spaces. It provides valuable insight into indoor air and helps identify and minimize sources of pollutants.

Conclusion

VOCs are omnipresent in many households, but with conscious measures you can significantly reduce your exposure to them. Good air quality contributes to health and well-being in the long term. Look for low-pollutant alternatives and ensure regular fresh air supply!
