Formaldehyde is a colourless gas with a strong odour, commonly used in the production of various household products, including furniture, flooring, and building materials.
In Singapore, this volatile organic compound (VOC) is prevalent in many construction and interior design materials, leading to concerns about indoor air quality and public health.
Formaldehyde can off-gas from products, contributing to indoor air pollution, which is particularly concerning in Singapore’s densely populated urban environment where ventilation may be limited.
Many construction materials, such as plywood, particleboard, and fiberboard, contain formaldehyde resins, which are synthetic compounds used as adhesives in the manufacturing process.
Formaldehyde resins are created through the reaction of formaldehyde with other substances, such as phenol or urea, resulting in durable and versatile materials widely used in the construction and furniture industries.
Formaldehyde-based resins, particularly urea-formaldehyde (UF) and phenol-formaldehyde (PF) resins, are integral to the production of engineered wood products. These resins enhance the strength, stability, and moisture resistance of materials, making them ideal for various applications, including cabinetry, flooring, and wall panels.
This popular building material is often made with layers of wood veneer bonded together using formaldehyde resins. Plywood is valued for its strength and versatility, making it suitable for both structural and decorative applications.
Composed of wood chips and particles bonded with adhesives, particleboard is commonly used in furniture and cabinetry. However, it is known to emit higher levels of formaldehyde compared to other wood products, particularly if not treated or sealed properly.
MDF is manufactured from wood fibres combined with resins under heat and pressure. It is known for its smooth surface, making it ideal for painted finishes. However, it typically contains a higher resin-to-wood ratio, resulting in greater formaldehyde emissions, especially in poorly ventilated spaces.
Common household items, such as adhesives, paints, and varnishes, can release formaldehyde into the air, contributing to indoor air pollution and posing potential health risks to residents.
These products often contain formaldehyde-based compounds that serve as preservatives or bonding agents, making them effective for various applications but also introducing harmful emissions into living spaces.
Adhesives are widely used in various household applications, from assembling furniture to installing flooring and wall coverings. Many conventional adhesives, particularly those used in woodworking and construction, contain urea-formaldehyde or phenol-formaldehyde resins.
When these adhesives are applied, they can off-gas formaldehyde, especially in the first few days after application. This off-gassing can persist for months or even years, depending on the product and environmental conditions.
Homeowners should be particularly cautious when using adhesives in poorly ventilated areas, as the concentration of formaldehyde can build up, leading to discomfort and health issues.
Particularly oil-based and some latex varieties, can also be significant sources of formaldehyde emissions. While many modern paints are formulated to be low-VOC, some still contain formaldehyde or formaldehyde-releasing preservatives to enhance shelf life and prevent microbial growth.
When paint is applied, it can release volatile organic compounds (VOCs), including formaldehyde, into the air. This is particularly concerning during and shortly after painting projects, as the fumes can linger in the air for extended periods.
Homeowners should consider using low-VOC or zero-VOC paints to minimise exposure and improve indoor air quality.
Varnishes, stains, and finishes used on wood surfaces are other common household products that may emit formaldehyde. These products are often used to enhance the appearance of furniture, cabinets, and flooring while providing a protective coating.
However, many varnishes contain formaldehyde-based solvents, which can release harmful fumes during application and drying. Like paints, the emissions from varnishes can persist long after the product has dried, especially in enclosed spaces.
To mitigate exposure, homeowners should opt for water-based finishes or those specifically labelled as low in formaldehyde and VOCs.
Some furniture pieces, especially those made from composite wood, may emit formaldehyde, which is a significant concern in the Singapore due to its potential health implications. Composite wood products, such as plywood, particleboard, and medium-density fiberboard (MDF), are commonly used in the manufacturing of furniture because they are cost-effective and versatile.
However, these materials often contain adhesives that are based on formaldehyde, leading to the release of this harmful gas into indoor environments.
Composite wood is created by binding together wood particles, fibres, or veneers with adhesives, resulting in a sturdy and affordable material.
This process allows for the production of furniture that is lightweight and easy to shape, making it a popular choice in Singapore’s bustling furniture market. However, the adhesives used in these products can off-gas formaldehyde, especially when the furniture is new or subjected to heat and humidity.
The health effects of formaldehyde exposure can vary significantly based on the concentration and duration of exposure, making it a critical concern for both residential and occupational environments.
Short-term exposure to formaldehyde, even at low concentrations, can lead to immediate health issues. Common symptoms include:
Inhalation of formaldehyde vapours can cause burning sensations, redness, tearing, and discomfort in the eyes. Similarly, individuals may experience irritation in the nose and throat, leading to symptoms such as coughing, sneezing, and a sore throat.
These effects can be particularly pronounced in poorly ventilated spaces or during activities that disturb formaldehyde-containing materials, such as renovation or cleaning.
People exposed to formaldehyde may also experience respiratory symptoms, including wheezing, chest tightness, and difficulty breathing. This is especially concerning for individuals with pre-existing respiratory conditions, such as asthma, who may find their symptoms exacerbated by formaldehyde exposure.
According to Dr. Steve Yang, a respiratory physician, these symptoms can develop rapidly, often within three to four hours after exposure, and may persist for hours or even days.
The long-term health implications of formaldehyde exposure are even more alarming. Prolonged exposure can lead to:
Continued inhalation of formaldehyde can contribute to the development of chronic respiratory conditions, such as bronchitis and chronic obstructive pulmonary disease (COPD).
These conditions are characterised by persistent inflammation of the airways, leading to reduced lung function and increased difficulty in breathing over time.
Some individuals may develop allergic sensitization to formaldehyde, resulting in skin reactions like contact dermatitis or respiratory allergies such as allergic rhinitis. These allergic responses can manifest as itching, redness, and swelling upon contact or inhalation of formaldehyde.
Formaldehyde has been classified as a human carcinogen by the International Agency for Research on Cancer (IARC). Long-term exposure has been associated with an increased risk of developing certain cancers, particularly nasopharyngeal cancer and leukaemia.
This risk is especially pronounced among individuals with prolonged occupational exposure, such as those working in industries involving wood processing, furniture manufacturing, and construction.
Emerging research suggests that formaldehyde exposure may also have neurotoxic effects, potentially impacting cognitive function and neurobehavioral performance. Individuals exposed to formaldehyde may experience symptoms such as headaches, memory issues, and difficulties with concentration.
Studies indicate that chronic low-level exposure could lead to long-term cognitive deficits, affecting daily functioning and quality of life.
Prioritise materials and products labelled as low-VOC or formaldehyde-free. This includes selecting paints, adhesives, and finishes that minimise harmful emissions. By opting for low-VOC paints and adhesives, can significantly reduce the potential for formaldehyde release, creating a healthier indoor environment.
Additionally, using water-based products instead of solvent-based ones can further decrease VOC emissions, ensuring that the living space remains safe for occupants.
Your interior designers should educate you and discuss about the potential sources of formaldehyde and the importance of selecting safer materials. Providing guidance on maintaining good indoor air quality can enhance client satisfaction and health. This education can include information on the risks associated with formaldehyde exposure and the benefits of choosing low-emission products.
Staying informed about local regulations regarding formaldehyde emissions and ensuring compliance in design projects is crucial. Singapore’s National Environment Agency (NEA) has mandated that interior paints sold in Singapore must be free of formaldehyde starting in 2026, reflecting ongoing public health protection efforts. Compliance with these regulations not only protects clients but also enhances the designer’s credibility.
Open windows and doors to allow fresh air to dilute indoor formaldehyde concentrations. This should be done consistently, especially during the first few weeks after renovation.
Invest in high-quality air purifiers equipped with HEPA filters and photocatalytic oxidation (PCO) technology to effectively reduce formaldehyde levels in the air.
Certain plants, such as spider plants and peace lilies, are known for their ability to absorb formaldehyde and other VOCs, making them both decorative and functional additions to the home.
Applying low-VOC sealants or varnishes to furniture and wood products can create a barrier that significantly lowers formaldehyde emissions.
Maintaining optimal humidity levels can help reduce formaldehyde off-gassing. Dehumidifiers can be used to keep humidity within a healthy range.

Hugo is a very experienced ID. Very creative while accommodating to our requirements. He is able to grasp how we envision the design and make it into reality. Quality and workmanship is excellence with reasonable pricing.
After sourcing for a few renovation companies' quotations, I finally selected Zenith Arc. Not because it was the cheapest. Rather, it was the vibes with id Jordan who gave off as friendly, patient, approachable. Basically, you can share any ideas with him and he will always listen intently, let you know if they worked or not, and if not, gave better suggestions and opinions as a professional in his field of knowledge! In addition, the 3D drawings of my prospective home designs was shown to me at just the 2nd meet up, which really put me in a clearer perspective of how my home would look like. Along the way, there were several changes in the designs and Jordan had no qalms about amending them and let me review again. His patience in this area was commendable👍. He also has a fantastic team of partners, right from carpenter Hong, electrician Jason and plumber Joshen, are all very friendly, approachable and skilful. Jordan is very responsive. Any rectification needed and when called upon, is done without delay. Friends and relatives who visited my house were very impressed with the design and workmanship done by Jordan, Zenith Arc. Highly recommended👍
We were working with Alan from Zenith and we came into contact with Zenith as we used the Qanvast platform to look for a designer to renovate our tired looking 40 year old HDB 5 room flat. When we were still shortlisting the designer, Alan came across as very professional, patient to understand our requirements and generously share his proposed design even before we confirm engaging him.After we have engaged his service, he accommodated our request to complete the renovation works much earlier than the original agreed date despite the unforeseen event that our floor tiles popped and had to change the entire overlaying laminate to tiles involving hacking. We started renovation in Oct and he rushed to complete the entire renovation works over the festive season of Christmas and New Year to hand over to us before CNY in early Feb with minimum defects.Currently, we are still covered under the 1 year warranty period and he is still very responsive whenever we call him to do some touch ups. We would definitely recommend Zenith if you are considering to renovate your homes.
Had a great experience over the last three meetings with Marc. He has been friendly, professional, and highly knowledgeable throughout the entire process. He answered all of my questions patiently and was very transparent in his recommendations and sharing. His professionalism gave us the confidence and peace of mind to entrust him with our home renovation when we collect the keys to our new home. Highly recommended!
We engaged Hugo for our new house. He coordinated the renovation well and gave practical suggestions for our house. He was responsive and attentive to our requests. A very good experience overall!
We completed our resale renovation with Wai Wai 3 years ago, and I wanted to come back to leave a review. 😊Wai Wai is very responsible and responsive, and I’d definitely recommend her if you’re looking for an ID with those qualities.As first-time homeowners, we had many late-night discussions about the design and materials. She was patient in answering all our questions and could quickly update the 3D design on the spot during meetings, which made the whole process much more efficient.She also provided a clear renovation schedule, so we always knew what to expect at each stage.While she didn’t visit the site often apart from key milestones, she was always responsive whenever we raised concerns or requested rectifications.The renovation wasn’t without issues. The carpentry workmanship initially had defects (such as bubbling laminates), and we also found some wavy plastering that required rework. In the months after handover, laminates and PVC edging started coming off some cupboards. However, what stood out was that Wai Wai took responsibility and arranged for her contractors to rectify the issues promptly—even a few years later while the extended warranty was still valid.Special mention to the tiler, who did an excellent job. Overall, while there’s room for improvement in the carpentry and plastering workmanship, Wai Wai’s professionalism, responsiveness, and after-sales support gave us confidence throughout the renovation journey.Three years on, my partner and I are still very happy with the comfortable home she helped us create, and we truly appreciate the effort she put into making it happen.

Shirley never made us feel rushed and was always willing to listen to our feedback and work through the changes with us.We wanted a home that wasn't just nice to look at but also practical for family living. Shirley took that into consideration during the planning stage and helped us come up with a layout that worked well for our daily routine. The renovation was completed within the expected timeline, which was something we were happy about. Even after handover, Shirley continued to follow up on the rectifications and made sure the outstanding items were settled.Overall, we're happy with our renovated home and would recommend Shirley to homeowners who are looking for an ID who is patient, easy to work with, and willing to listen to what you want.
Engaged my interior designer Ken Tay from Zenith Arc in 2024 for my condo renovations. He was able to provide suggestions and ideas to cater to my expected look and feel to the home. 2-3 years on, he is equally responsive and helpful to my asks. Great after sales support is something that is extremely rare and underrated in this industry that should not be taken for granted. I am glad to have made the right decision to engage Ken, no regrets.
