ARE VOLATILE ORGANIC COMPOUNDS (VOCS) MAKING YOU SICK?
Admin • Jun 15, 2017
You can’t talk about Indoor Air Quality
without mentioning the effects of VOCs.
VOC is an acronym for Volatile Organic Compounds, which are “carbon-containing organic chemicals present in indoor air” (Introduction to VOCs and Health). And they’re making you sick.
Thousands of everyday products emit organic chemicals into the air. Additionally, VOCs are present in household staples such as cleaning products, paints, furnishings, and pesticides.
According to the Environmental Protection Agency, “Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors.”
Buildings with heavy concentrations of VOCs are sometimes referred to as having “Sick Building Syndrome.”
There are a wide variety of VOCs that can be found in the home. Some give off a bad smell, but even odorless organic chemicals can also have adverse effects on our health. It all depends on concentration levels.
Common Household VOCs
Acetone
– furniture polish, wallpaper
Benzene
– paint, carpeting
Butanal
– stoves, cigarettes
Carbon Disulfide
– chlorinated tap water
Dichlorobenzene
– deodorizers
Ethanol
– dish and laundry detergents
Formaldehyde
– the most common indoor VOC, found in floor lacquers and certain plastics
Terpenes
– soaps and detergents with fragrance
Toluene
– paint
We don’t think about it on a daily basis, but VOCs are ever-present. When possible, always choose VOC-free paints, detergents and deodorizers.
Buy acetone-free nail polish remover and water-based furniture polish substitutes. When using a product known to contain VOCs, ensure proper ventilation in the home and store the products outside of the home, in the garage or a storage shed.
Products that contain VOCs:
- Paint (and other solvents)
- Wood Preservatives
- Aerosol Sprays
- Cleansers & Disinfectants
- Moth Repellents & Air Fresheners
- Stored Fuels & Automotive Products
- Hobby Supplies
- Dry Cleaned Clothing
- Cosmetics
- Pesticides
- Building Materials & Furnishings
- Upholstery and Foam
- Office Equipment (e.g., copiers and printers, correction fluids, and carbonless copy paper)
- Graphics & Craft Materials (including glues and adhesives, permanent markers and photographic solutions)

How do VOCs affect my health?
The health effect and the severity of it really depends on the level of concentration and the length of exposure to the VOC. Short term exposure to certain VOCs may produce headaches and a worsening of asthma symptoms and respiratory issues. Long term exposure to indoor VOCs will cause liver or kidney damage and even cancer.
Health effects may include:
- Eye, nose & throat irritation
- Headaches, loss of coordination & nausea
- Damage to liver, kidney & central nervous system
- Some organics can cause cancer in animals
- Some are suspected or known to cause cancer in humans.
Key signs or symptoms associated with exposure to VOCs include:
- Conjunctival irritation
- Nose & throat discomfort
- Headache
- Allergic skin reaction
- Dyspnea
- Declines in serum cholinesterase levels
- Nausea
- Emesis
- Epistaxis
- Fatigue
- Dizziness

How to Clear Home of Volatile Organic Compounds
Pollutant Source Removal & Air Distribution
One of the best ways to keep VOCs out of the home is knowing where they come from and how to control them.
- Stay away from products that contain VOCs as much as possible. Find out which products have VOCs (the National Institute of Health’s website is a great resource).
- If you have any products that contain VOCs, store them in a sealed container away from all living spaces. These include paints, adhesives, solvents, and pesticides. A garage, shed, or another well-ventilated area will do the trick.
- Buy products containing VOCs in small quantities that are used up quickly so you don’t have to store them.
- Dispose of VOCs properly. Since many VOC products are considered hazardous waste, contact your town or visit savethebay.com to learn how to recycle and dispose of household toxics.
- Always use VOC products in well-ventilated areas without any people around. Better yet, use products containing VOCs outdoors. Open windows and doors, and use an exhaust fan. Select the proper respirator for the job with the 3M Respirator Selection Guide.
- Allow time for new building materials and renovations to ventilate
- Have a qualified HVAC technician conduct routine annual maintenance of your HVAC system. Ask your technician about air cleaning, filtration, ventilation, and other indoor air quality solutions.
- Inspect HVAC air filters every 30 days and replace them every 30-60 days.
- Replace water-stained ceiling tiles, furniture, rugs and carpeting if necessary.
- Enforce no smoking rules indoors.
- Install a heat recovery ventilator (HRV) to solve poor air quality and lack of ventilations. An HRV refreshes stale air by introducing outside air while removing indoor air through an exhaust vent. Every home should have an HRV and working exhaust fans in the kitchen and bathroom.
Air Cleaning
Air cleaners won’t solve all of your VOC and air quality problems, but they will certainly help.
- Control indoor air pollutants and capture small particles with clean and effective air filters (minimum MERV rating of 7). The higher the Minimum Efficiency Reporting Value (MERV) rating, the better the filtration. HEPA (High Efficiency Particulate Air) filters are the best, however, you may need to modify your HVAC equipment. Speak with an HVAC technician for more information.
- HVAC filters do not remove gaseous pollutants.
- Some air purification products, such as UV air cleaners. can effectively reduce VOCs in the home, but there are limitations.
