From Furniture to Flooring: Common Sources of Formaldehyde & VOCs Indoors

Indoor air quality can be affected by far more than mold or excess moisture. Many everyday household products and building materials can release volatile organic compounds, or VOCs, into the air. Formaldehyde is one of the better-known VOCs and may be present in furniture, flooring, cabinetry, paints, adhesives, insulation, and other materials found throughout a home.

For homeowners throughout Massachusetts and New Hampshire, understanding where these compounds may come from can be an important part of evaluating indoor air quality, especially after renovations, installation of new materials, or when persistent odors or other indoor air concerns are present.

What Are VOCs?

VOCs are chemicals that can evaporate into the air from certain solids and liquids. They may be released from both newly installed and existing products inside a home. Some VOCs have noticeable odors, while others may be present without producing a strong smell.

Concentrations can vary depending on the material involved, ventilation, temperature, humidity, product age, and how much of the material is present. Newly manufactured products often release higher levels initially, a process commonly referred to as off-gassing.

What Is Formaldehyde?

Formaldehyde is a specific VOC commonly associated with manufactured wood products, adhesives, resins, furniture, flooring, cabinetry, insulation, and certain household products.

It may be present in homes at low concentrations as part of normal indoor environments, but elevated levels can sometimes occur when several emitting materials are present or when ventilation is limited.

Common Sources of Formaldehyde and VOCs in Homes

Furniture

Furniture made with particleboard, medium-density fiberboard, plywood, laminates, adhesives, finishes, or composite materials may release VOCs after manufacturing. New desks, shelving, dressers, bed frames, and upholstered furniture can all contribute to indoor emissions.

Flooring

Laminate flooring, engineered wood, vinyl products, carpeting, adhesives, underlayment, sealers, and finishes can all be possible VOC sources.

Cabinets and Built-In Wood Products

Kitchen cabinets, bathroom vanities, shelving, closets, and other built-in products are often constructed with manufactured wood and adhesives.

Paints, Coatings and Finishes

Paint, polyurethane, stains, varnishes, primers, caulks, sealants, and similar products may release VOCs during and after application.

Adhesives and Construction Materials

Construction adhesives, flooring glue, wall coverings, insulation products, sealants, composite wood, and other renovation materials can contribute VOCs, especially shortly after installation.

Cleaning and Household Products

Cleaning products, fragrances, air fresheners, solvents, disinfectants, personal care products, and stored chemicals may also contribute VOCs to indoor air.

Why New Construction and Renovations Can Affect Indoor Air Quality

A newly renovated home may contain multiple new sources at the same time: flooring, cabinets, paint, trim, insulation, adhesives, furniture, and finishes. Each individual source may contribute only part of the overall indoor VOC level, but together they may have a more noticeable effect.

Can Humidity Affect Formaldehyde and VOC Emissions?

Indoor temperature and humidity can influence how certain materials release chemicals into the air. Warmer conditions and elevated humidity may increase emissions from some products and building materials.

Maintaining appropriate indoor humidity can be helpful for overall building performance and comfort, but a dehumidifier does not identify which VOCs are present and should not be considered a substitute for testing.

When Should You Consider VOC or Formaldehyde Testing?

• Persistent chemical or unusual odors
• Recent renovations or remodeling
• New flooring, cabinetry or furniture
• Newly constructed homes
• Concerns involving manufactured wood products
• Suspected formaldehyde exposure
• Ongoing indoor air quality concerns

Professional VOC and formaldehyde testing can provide laboratory data rather than relying solely on odors or visible conditions.

VOC Testing vs. Formaldehyde Testing

VOC testing and formaldehyde testing are related, but they are not necessarily the same test. A broader VOC analysis may evaluate a range of volatile compounds, while formaldehyde testing is specifically designed to measure formaldehyde.

Frequently Asked Questions

Can formaldehyde come from furniture?

Yes. Some furniture contains composite wood, adhesives, resins, finishes, or other materials that may release formaldehyde or other VOCs.

Can flooring release VOCs?

Yes. Certain flooring materials, adhesives, underlayments, coatings, and finishes may release VOCs, particularly after installation.

Does opening windows help with VOCs?

Increased outdoor-air ventilation can sometimes reduce the concentration of indoor pollutants, but effectiveness depends on the source, building conditions, outdoor air, and the compounds involved.

Can you smell formaldehyde?

Formaldehyde may have a noticeable odor at certain concentrations, but odor alone cannot determine the actual concentration in the air.

How do you know if VOC levels are elevated?

Laboratory-based air sampling can provide measured data. Visual inspection and odor observations alone cannot determine specific VOC concentrations.
