Formaldehyde & VOCs in Your Home: What You Need to Know
Learn where formaldehyde and VOCs may come from, how they can affect indoor air quality, ways to reduce exposure, and when professional VOC and formaldehyde testing may be appropriate.
The air inside your home matters. Homes throughout Massachusetts and New Hampshire can contain indoor pollutants released by building materials, furniture, flooring, paints, adhesives, cleaning products, and other everyday materials.
Two common categories are formaldehyde and volatile organic compounds (VOCs). Understanding where these chemicals may come from — and when professional testing may be appropriate — can help homeowners make more informed indoor air quality decisions.
What Are VOCs and Why Should You Care?
Volatile Organic Compounds, commonly called VOCs, are chemicals that can become gases at room temperature. Formaldehyde is one of many VOCs that may be found inside residential buildings.
VOCs may be released through a process commonly referred to as off-gassing. Sources can include recently installed building materials, furnishings, household chemicals, finishes, adhesives, and manufactured wood products.
Common indoor sources may include:
- Pressed-wood products such as particleboard and MDF
- Kitchen cabinets and manufactured furniture
- Carpets, rugs, and certain treated fabrics
- Paints, coatings, adhesives, and varnishes
- Cleaning products and air fresheners
- New flooring and remodeling materials
Potential Effects of Formaldehyde & VOC Exposure
Exposure to certain VOCs may contribute to irritation of the eyes, nose, or throat. Depending on the compound, concentration, exposure duration, and individual sensitivity, some people may also experience headaches, coughing, dizziness, or other symptoms.
Indoor VOC concentrations can vary substantially from one home to another. The presence of an odor alone does not determine whether a particular compound is present at an elevated concentration.
Short-Term Exposure
Some VOCs may cause temporary irritation, headaches, odors, coughing, or discomfort when concentrations are elevated.
Long-Term Exposure
Potential health effects vary significantly depending on the individual chemical, exposure level, and duration.
Why Low-VOC and Formaldehyde-Free Products Matter
Reducing the number of high-emitting products introduced into a home can help limit potential indoor VOC sources. This can be particularly useful when purchasing new furniture, replacing flooring, installing cabinets, painting, or completing renovations.
Lower-emitting materials may help:
- Reduce potential indoor sources of VOCs
- Limit chemical off-gassing from newly installed materials
- Improve control over pollutants introduced during renovations
- Support better overall indoor air quality
Formaldehyde & VOCs in Building Materials
Building materials can be an important source of indoor VOC emissions. Pressed wood, particleboard, MDF, adhesives, flooring products, coatings, paints, and manufactured furniture may release VOCs after installation or manufacturing.
When building or renovating, homeowners may choose to review product emissions information and consider lower-emitting alternatives when available.
Pressed Wood
Particleboard, MDF, cabinetry, shelving, and manufactured furniture may contain adhesives capable of releasing formaldehyde.
Flooring & Finishes
Flooring systems, adhesives, coatings, stains, sealers, and finishes may introduce additional VOC sources.
Paints & Coatings
Some paints and coatings may emit VOCs during application and while curing.
New Furniture
Recently manufactured furniture and upholstered products can sometimes produce noticeable off-gassing after delivery.
How to Reduce VOCs in Your Home
There are several practical ways homeowners can reduce potential sources of VOC exposure indoors.
- Increase ventilation. Open windows when conditions permit and use mechanical exhaust where appropriate.
- Choose lower-emitting products. Look for low-VOC paints, finishes, flooring, furniture, and building products.
- Store chemicals properly. Keep paints, solvents, fuels, cleaners, and similar products sealed and appropriately stored.
- Limit fragrances. Air fresheners, scented sprays, and other fragrance products may contribute additional VOCs.
- Consider gas-phase filtration. Activated carbon and other specialized filtration media may help reduce certain airborne chemicals.
How Do You Know If Your Home Has VOCs?
VOCs are not always detectable by smell. Some compounds produce noticeable chemical odors, while others may be present without an obvious warning sign.
Homeowners may consider VOC or formaldehyde testing following:
- New construction
- Major renovations
- New flooring installation
- New kitchen cabinets or built-ins
- Purchase of new furniture
- Persistent or unusual chemical odors
- General indoor air quality concerns
Professional VOC & Formaldehyde Testing
When homeowners have a specific concern about chemical exposure or indoor air quality, professional sampling can provide more useful information than relying on smell or consumer-grade air-quality sensors alone.
Professional testing may involve collecting indoor air samples using sampling media selected for the contaminants being investigated. Samples are then submitted to a laboratory for analysis.

Creating a Healthier Indoor Environment
Formaldehyde and VOCs can originate from many common materials inside a home. Building products, flooring, cabinetry, furniture, paints, adhesives, cleaning products, and fragrances are only some potential sources.
Reducing unnecessary sources, improving ventilation, selecting lower-emitting materials, and performing professional testing when appropriate can provide homeowners with a better understanding of their indoor environment.
Frequently Asked Questions About Formaldehyde & VOCs
They can originate from pressed-wood furniture, flooring, cabinetry, carpets, paints, adhesives, cleaning products, fragrances, and many other building and household materials.
Yes. VOCs are one category of indoor air pollutants. Their concentrations can vary depending on products inside the home, ventilation, temperature, material age, and other environmental conditions.
Professional air sampling can be performed using sampling equipment and laboratory analysis selected for the specific contaminants being investigated.
Ventilation, reducing chemical sources, choosing lower-emitting products, storing chemicals properly, and using appropriate filtration may help reduce indoor concentrations.
New flooring, cabinetry, furniture, adhesives, paints, coatings, and other recently installed materials may release VOCs after installation.
