What Allergy Sufferers Need to Know About the Hidden Hazards of VOCs and SVOCs

In addition to common allergens such as pollen and dust mites, VOCs and SVOCs are often overlooked allergens for allergy sufferers. These volatile organic compounds and semi-volatile organic compounds can be present in indoor environments and pose potential risks to human health.


  1. Definition and Sources of VOCs and SVOCs

Volatile organic compounds (VOCs) are chemicals that have a high vapor pressure at room temperature. This means that they easily evaporate into the air. Common sources of VOCs include household products, building materials, cleaning agents, and personal care products. Semi-volatile organic compounds (SVOCs) are compounds that have a lower vapor pressure at room temperature than VOCs. However, they can still release chemicals into the air. Common sources of SVOCs include plastic products, furniture, carpets, and coatings.


  1. The Impact of VOCs and SVOCs on Health and Allergies

2.1 Respiratory irritation: The release of VOCs and SVOCs can cause respiratory discomfort, such as throat irritation, coughing, and worsening asthma symptoms.

2.2 Allergic reactions: Certain VOCs and SVOCs can trigger or exacerbate allergy symptoms, such as nasal congestion, coughing, and skin allergies.

2.3 Toxic effects: Some VOCs and SVOCs are considered to have potential toxic effects and may have negative impacts on the liver, nervous system, and immune system.


  1. Identifying and Reducing Exposure to VOCs and SVOCs

3.1 Indoor air quality testing: Conduct indoor air quality testing to understand the concentration and sources of VOCs and SVOCs. This will enable you to take appropriate measures to reduce your exposure.

3.2 Choosing low-volatile products: Opt for household products, cleaning agents, and personal care products with lower levels of volatile organic compounds.

3.3 Indoor ventilation: Maintain good indoor ventilation to increase air circulation. This helps dilute and remove indoor pollutants.

3.4 Using air purifiers: Select air purifiers equipped with activated carbon filters, which can adsorb VOCs and SVOCs, providing cleaner indoor air.



Understanding and addressing the hidden hazards of VOCs and SVOCs is crucial for allergy sufferers. By identifying sources, choosing low-volatile products, improving indoor ventilation, and using air purifiers, we can reduce exposure to VOCs and SVOCs, creating a healthier and more comfortable indoor environment. Protecting oneself from the impact of VOCs and SVOCs allows allergy sufferers to enjoy a better quality of life.
