Understanding the Dangers of Formaldehyde in Your Home

Formaldehyde is a colorless, strong-smelling gas commonly found in building materials, furniture, and everyday household products. While it occurs naturally in small amounts, higher concentrations indoors can create serious health risks. For homeowners, understanding formaldehyde is essential to keeping your living space safe and comfortable.

Why Formaldehyde Matters

Even if you don’t notice it, formaldehyde can impact your health in several ways:

• Irritation of Eyes, Nose, and Throat
  Exposure can cause burning or watery eyes, coughing, sneezing, and a scratchy throat.
• Respiratory Issues
  Those with asthma, allergies, or other conditions may notice worsened symptoms in spaces with high formaldehyde levels.
• Allergic Reactions
  Some people develop rashes or skin sensitivities from exposure to products that emit formaldehyde.
• Long-Term Health Risks
  According to the U.S. Environmental Protection Agency (EPA) and World Health Organization (WHO), formaldehyde is a known human carcinogen. Long-term exposure has been linked to cancers of the nasal passages and throat.

How Formaldehyde Gets Into Your Home

Formaldehyde can be released—or “off-gassed”—from many common sources, especially in newer or recently renovated homes:

• Building Materials
  Plywood, particleboard, pressed wood, insulation, and certain flooring contain adhesives with formaldehyde. Levels are often highest in new construction or remodeled homes.
• Furniture and Cabinets
  Manufactured wood products such as affordable furniture, kitchen cabinets, and shelving may release formaldehyde for months.
• Household Products
  Paints, glues, adhesives, cleaning solutions, and textiles (like wrinkle-free fabrics) can contribute to indoor levels.
• Combustion Sources
  Cigarette smoke, fireplaces, and gas stoves all release formaldehyde.

Signs You Might Have Elevated Formaldehyde Levels

It isn’t always obvious when indoor air contains too much formaldehyde, but your body often reacts before you realize what’s happening. Homeowners should pay attention to the following warning signs:

• Persistent irritation
  Burning or watery eyes, a scratchy throat, or a constant cough indoors may point to elevated levels.
• Frequent headaches or dizziness
  If these symptoms improve when you leave home, poor air quality could be the cause.
• Worsening asthma or respiratory discomfort
  Those with existing conditions may notice flare-ups that seem to occur mainly at home.
• Chemical odors
  A strong smell from new furniture, flooring, or cabinets can indicate off-gassing of formaldehyde.

How to Reduce Exposure in Your Home

Fortunately, there are practical steps every homeowner can take to lower formaldehyde exposure and improve overall indoor air quality:

• Improve ventilation by opening windows whenever possible, running exhaust fans in kitchens and bathrooms, or installing a whole-home air exchange system.
• Choose low-emission products when buying new furniture, cabinets, or flooring. Look for formaldehyde-free or low-VOC certifications.
• Control humidity since moisture in the air accelerates off-gassing. Keeping indoor humidity between 30% and 50% helps limit the problem.
• Avoid indoor smoking, as cigarette smoke is one of the most concentrated household sources of formaldehyde.
• Use air purifiers equipped with HEPA and activated carbon filters to help capture pollutants and freshen the air.
