How to remove formaldehyde from furniture?


Formaldehyde is a common chemical used in the manufacturing of furniture, particularly in composite wood products like plywood, particleboard, and MDF. While these materials are affordable and widely used, they can release formaldehyde gas into the air, which can pose health risks. In this article, we will explore various methods to remove formaldehyde from furniture, ensuring a healthier and safer living environment.

Understanding Formaldehyde

Formaldehyde is a colorless gas with a pungent odor. It is commonly used in furniture manufacturing as a binding agent in composite wood products. However, prolonged exposure to formaldehyde can cause respiratory issues, eye irritation, and even cancer in some cases. Therefore, it is crucial to minimize or eliminate formaldehyde emissions from furniture.

Testing for Formaldehyde

Before attempting to remove formaldehyde from furniture, it is essential to determine if it is present. You can use a formaldehyde test kit, readily available in hardware stores or online, to detect formaldehyde levels in your furniture. Follow the instructions provided with the kit to obtain accurate results.

Methods to Remove Formaldehyde

Ventilation: One of the simplest ways to reduce formaldehyde levels is by improving ventilation. Open windows and use fans to increase airflow in the room. This helps in dissipating the formaldehyde gas and replacing it with fresh air.

Activated Charcoal: Activated charcoal is known for its ability to absorb odors and chemicals. Place bowls filled with activated charcoal near the furniture to absorb formaldehyde over time. Replace the charcoal periodically to maintain its effectiveness.

Baking Soda: Baking soda is another natural absorbent that can help remove formaldehyde. Sprinkle baking soda on the furniture’s surface, let it sit for a few hours, and then vacuum it off. Repeat this process regularly to reduce formaldehyde levels.

Vinegar: Vinegar is a versatile household ingredient that can also help eliminate formaldehyde. Mix equal parts of vinegar and water in a spray bottle and mist the furniture’s surface. Wipe it clean with a cloth after a few minutes. Vinegar’s acidic nature helps neutralize formaldehyde.

Activated Carbon Filters: Consider using air purifiers or HVAC systems with activated carbon filters. These filters are designed to trap and remove formaldehyde and other volatile organic compounds (VOCs) from the air, improving indoor air quality.

Preventing Formaldehyde Emissions

While removing formaldehyde from furniture is essential, preventing its release in the first place is equally important. When purchasing new furniture, opt for products labeled as low-VOC or formaldehyde-free. These products are manufactured using safer alternatives and have minimal formaldehyde emissions.

Additionally, consider applying a sealant or coating to the furniture’s surface to prevent formaldehyde gas from escaping. Consult with professionals or refer to manufacturer guidelines for suitable sealants.


Removing formaldehyde from furniture is crucial for maintaining a healthy indoor environment. By implementing methods such as ventilation, activated charcoal, baking soda, vinegar, and activated carbon filters, you can effectively reduce formaldehyde levels. Remember to test for formaldehyde before applying any removal techniques and prioritize purchasing low-VOC or formaldehyde-free furniture to minimize exposure.
