Office Chair Has a Strong Odor
The strong odor of newly purchased office chairs can be addressed through methods such as ventilation and physical adsorption. The intensity of the odor does not necessarily equate to poor quality or formaldehyde overexposure. Ultimately, safety should be determined based on professional testing results.
Sources of Odor
The sources of odor in newly purchased office chairs are diverse. Firstly, formaldehyde, primarily from the urea-formaldehyde resin adhesive used in artificial wood panels, is continuously and slowly released over a period of 3 to 15 years, and may have no noticeable odor at low concentrations. Secondly, the natural odor of wood itself: solid wood contains natural volatile organic compounds that emit a woody fragrance or a special odor, which is usually harmless and will significantly diminish after 2 to 4 weeks of ventilation. Thirdly, volatile substances from paints and coatings: the surface coatings of desks and chairs release benzene series and TVOC during the curing process, producing a pungent or sweet odor. Fourthly, other sources: adhesives used in furniture manufacturing, processing residues from seat textiles, and plastic films used for packaging can also contribute to short-term odors; the pungent smell of new leather office chairs mainly originates from volatile organic compounds in the adhesives and coatings used during the manufacturing process.
Judgment Methods
The intensity of the odor does not necessarily equate to poor quality or formaldehyde overexposure. The key to judgment lies in distinguishing the type of odor and whether it causes physical discomfort. If the odor is pungent and accompanied by symptoms such as dry eyes, a tight throat, tearing, a dry and itchy throat, coughing, dizziness, headaches, skin allergies, or chest tightness, and these symptoms alleviate after leaving the environment, this strongly suggests the possibility of overexposure to harmful gases (such as formaldehyde and TVOC).
Removal Methods
Firstly, ventilation: continuous and strong ventilation is the most effective and free basic method. Place the chair in a well-ventilated area; an environment with through ventilation and windows that can be opened for 8 to 12 hours a day yields the best results. Spaces with poor ventilation require more time. Generally, after about a week of ventilation, the odor of leather office chairs will significantly reduce. Continuous treatment for 3 to 6 months can reduce indoor pollutant concentrations to safe levels. Secondly, physical adsorption: place activated carbon near the chair, paying attention to the replacement cycle; you can also place orange peels, green tea leaves, etc., or use specialized odor removal products such as charcoal packs and deodorizers. Thirdly, wipe the chair several times with a damp cloth to remove residual chemicals from the surface.
Testing Recommendations
Ultimately, safety should be determined based on professional testing results. You can simply use a formaldehyde detector for measurement; a reading exceeding 0.08mg/mยณ is considered unsafe.
