New Office Chair Odor

The odor of a new office chair is not necessarily from formaldehyde; it may come from various substances. Whether it is safe needs to be determined based on physical reactions and scientific testing.

Sources of Odor

1. Formaldehyde: Mainly derived from urea-formaldehyde resin adhesives in artificial wood panels (such as medium-density fiberboard and particleboard). It has a pungent odor and can be released for 3 to 15 years. However, low concentrations of formaldehyde may have no obvious odor, making it difficult to detect by smell alone.
2. Paint/Coating Volatiles: Such as benzene series compounds (benzene, toluene, xylene, etc.), which usually have a fragrant or pungent odor. They mainly come from coatings on the surface of desks and chairs, such as varnish, wood wax oil, and polyurethane paint. In low- to mid-end furniture, the concentration of benzene series compounds may exceed standards by 2-3 times, but 90% can volatilize within six months.
3. Natural Wood Odor: Solid wood (such as pine and camphor wood) contains natural volatile organic compounds like terpenes and esters, which emit a unique woody fragrance or special odor. These are usually harmless and will significantly weaken after 2 to 4 weeks of ventilation.
4. Other Sources: Adhesives used in furniture manufacturing, processing residues from seat textiles, and plastic films used for packaging may also cause short-term odors.

Methods to Determine if the Odor is Harmful

• Physical Signals: If symptoms such as eye irritation, dryness, tearing, sore throat, coughing, dizziness, headache, skin allergies, or chest tightness occur, and these symptoms improve after leaving the environment, it may indicate excessive levels of harmful gases (such as formaldehyde and TVOC).
• Odor Characteristics: Strong, pungent, eye-irritating chemical odors or sour smells that do not significantly improve after several weeks of continuous ventilation indicate a higher risk of exceeding standards.

Methods to Remove Odor

• Enhanced Ventilation: Continuous and strong ventilation is widely recognized as the most effective and free basic method. Environments with north-south ventilation and windows that can be opened for 8-12 hours a day yield the best results.
• Physical Adsorption: Place 200 grams of activated carbon per square meter and replace it every three days.
• Professional Product Assistance: For example, using white vinegar to wipe surfaces can remove ammonia odors, and keeping Monstera plants can also improve air purification.
• Heating to Accelerate Volatilization: Heating furniture to 40 degrees Celsius with an electric blanket can quadruple the volatilization rate.

Ultimately, whether it is safe should be determined based on professional testing results.
