Ensuring that your home or business has safe, clean air can improve health and wellbeing, while also protecting from dangerous gases and particulates. Volatile Organic Compounds (or VOCs) represent some of the most prolific air quality hazards. These toxic airborne particles can pose multiple health hazards and need to be effectively filtered out to achieve optimal air quality.

VOCs can come from a vast range of common sources, including popular cleaning products, fragrances, furniture, and paint, among many others. The good news is that it's possible to remove VOCs from your indoor air with the right strategy and tools. This article will help to provide a deeper understanding of VOCs and explore several ways to mitigate and eliminate them from your home or business, including using a VOC air purifier.

What Are VOCs?

According to the U.S. Environmental Protection Agency ( EPA ), VOCs are toxic chemicals emitted as gases from certain solids or liquids. Airborne pollutants may have short and long-term adverse health effects VOCs have become basic ingredients in many everyday products and materials. For that reason, they're one of the hardest toxins to avoid. Worse, few types of contaminants carry as many health implications.

“Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors,” reports the EPA. “VOCs are emitted by a wide array of products numbering in the thousands,” “Have you ever pumped gas, had your clothes dry cleaned, or used chlorine bleach in your laundry or for disinfection? Then you're likely to have encountered VOCs…many of these chemicals are toxic and can pose human-health or ecological concerns.” - United States Geological Survey But don't panic! We have a variety of methods and equipment that can help to keep VOCs out of your space.

To better understand VOCs and how to manage them, we must first identify their origins.

Common Sources of VOCs VOCs come from a staggering variety of places, including household cleaners and disinfectants, air fresheners, and aerosol sprays. Smoke from wood-burning stoves, cooking , tobacco, and wildfires also contains volatile organic compounds. So do many paints and glues.

VOCs are often present when you can smell a strong chemical scent. That's especially true for new furniture, carpet, and electronics, which release VOCs in a process called “off-gassing”.

The most notorious VOCs include formaldehyde, benzene, and butanol.

Here are the top sources of household VOCs, according to the EPA:

  • Paints, paint strippers, and other solvents
  • Wood preservatives
  • Aerosol sprays
  • Cleansers and disinfectants (bleach and ammonia)
  • Moth repellents and air fresheners
  • Stored fuels and automotive products
  • Hobby supplies
  • Dry-cleaned clothing
  • Pesticide
  • Building materials and furnishings (especially particle board furniture)
  • Office equipment such as copiers and printers
  • Glues, adhesives, and permanent markers

When working with these products, it is important to wear a protective mask and ideally run a VOC air purifier.

Are VOCs Dangerous?

Yes, VOCs can be extremely dangerous and lead to serious health problems, with enough exposure. According to the American Lung Association VOCs are “harmful by themselves, including some that cause cancer. In addition, they can react with other gases and form other air pollutants after they are in the air.” Caution should be taken when dealing with VOCs, especially if the area lacks ventilation or proper air filtration.


EPA reports that VOCs often cause eye, nose, and throat irritation, nausea, and can also damage the liver, kidney, and central nervous system. These are especially harmful to those with chemical sensitivities. 

Other common symptoms include:

  • Frequent headaches
  • Allergic skin reaction
  • Fatigue
  • Dizziness

Which VOCs are Dangerous?

These VOCs can be found in a wide variety of common products. When possible, avoid direct contact with them. Products that contain them should be stored in a safe, well-ventilated area away from your living space (such as a garage or outdoor shed). Here’s a list of VOCs that should be managed with caution:

  • Acetone
  • Xylene
  • Benzene
  • Butanal
  • Carbon Disulfide
  • Dichlorobenzene
  • Terpenes
  • Methylene Chloride
  • Ethanol
  • Formaldehyde
  • Toluene

If you are experiencing these symptoms on a regular basis or when working with products that contain VOCs, you should create a plan to mitigate VOCs and improve air quality. The health benefits of using a VOC air purifier can have significant short and long term advantages.

VOC Exposure Limits

According to the environmental technology solutions group TECAM, “TVOC (total concentration of multiple VOCs) can be measured in micrograms per cubic meter (µg/m3) of air, milligrams per cubic meter (mg/m3), parts per million (ppm) or parts per billion (ppb).”

The following chart will help to breakdown when the levels of VOCs in the air become dangerous:

TVOC Level mg/m3

Level of Concern


Less than 0.3 mg/m3


Painting a Room

0.3 to 0.5 mg/m3


Disinfecting a Bathroom

0.5 to 1 mg/m3


Automotive Garage Fumes

1 to 3 mg/m3


Spraying Pesticides Inside

How to Remove VOCs

The good news is that there are three easy and effective ways to ensure that your indoor environment is clean and free of dangerous VOCs.

  1. Control and remove the sources of VOCs: Eliminating the sources of VOC vapors should be your first step. For example, avoid harsh chemicals and store things like paint, fuel, and chemicals far away from your living space. Choose nontoxic cleaning products and shop for low or no-VOC paints and finishes. Many common household products are packed with VOCs. So, simply removing them is a quick and practical method that will immediately improve your air quality.
  2. Use as directed: Never mix chemicals such as household cleaners, unless directed to do so on the label. Mixing chemicals can result in the creation of deadly gases or volatile reactions. Always store household products that contain chemicals according to manufacturers' instructions. And keep all products away from children and pets!
  3. Bring in fresh air: Outdoor, fresh air can help to improve your air quality. Increasing ventilation may be especially beneficial in modern, energy-efficient homes and apartments, which are built relatively airtight to save on energy costs but can end up trapping and circulating VOCs. However, be aware that outdoor air also introduces new particles like pollen and other air pollution, which can trigger allergy or asthma symptoms, as well as other respiratory issues.
  4. Get a True HEPA air purifier for VOCs: For a truly healthy indoor environment, you must actively remove VOC chemical particles, as well as the allergens and other irritants that can come from outside. You'll need an air purifier with appropriate capacity for your room and one that's equipped with a True HEPA Carbon filter, such as the Alen BreatheSmart True HEPA Air Purifier, which is designed to actively combat and cleanse airborne hazards like volatile organic compounds.
