The Pungent Smell of Office Chairs

The pungent smell of office chairs does not necessarily indicate formaldehyde overexposure; it may be caused by benzene series compounds, TVOC (Total Volatile Organic Compounds), or natural wood volatiles, among others. These can be addressed through ventilation, activated carbon adsorption, and wiping clean, with the final determination based on professional testing results.

Possible Sources of the Pungent Smell

Formaldehyde itself is usually odorless and only produces a stinging sensation at extremely high concentrations. Therefore, the pungent smell is more likely to come from other substances:

• Benzene series compounds: Commonly found in paints and coatings, they may have a floral or pungent odor and can cause dizziness and nausea upon short-term exposure.
• TVOC (Total Volatile Organic Compounds): Widely sourced, including adhesives and plastics, they may cause immune system disorders.
• Natural wood volatiles: Such as the pine resin smell from pine wood, which is usually harmless and gradually dissipates after ventilation.

Targeted Treatment Measures

1. Ventilation:
   Continuous and strong ventilation is the core method, accelerating the volatilization of pollutants through air circulation. It is recommended to adopt a strategy of "strong ventilation as the main approach, supplemented by physical adsorption and professional products," which can significantly reduce pollutant concentrations within 3 to 6 months.

2. Using activated carbon packs:
   Activated carbon can adsorb some volatile substances, but attention should be paid to the dosage and replacement cycle. It is recommended to place 200 grams of activated carbon packs per 10 square meters and replace them weekly to avoid secondary release after adsorption saturation.

3. Wiping with a damp cloth:
   Wiping the surface of the chair multiple times with a damp cloth can remove residual chemicals and reduce the source of volatilization. This method is more effective for water-soluble pollutants.

Precautions Regarding Testing Reports

Some merchants may provide false testing reports, so caution is required. For example, in a case in Shenzhen, the "qualified" report presented by a merchant had the same report number as an "unqualified" report stored on the official website. The final safety should be determined based on the testing results from professional institutions, avoiding reliance solely on documents provided by merchants.

Summary

The pungent smell should be addressed based on its source, with ventilation as the foundation and activated carbon and wiping as supplementary methods. If the smell persists or is accompanied by physical discomfort, it is recommended to contact a professional institution for testing to ensure health and safety.
