What Are VOCs and Odors?

This time, I’ll cover an important topic and explain the meaning behind VOCs and odors.

I’ve reviewed many air purifiers, and most of them include an activated carbon filter. This filtration layer helpsadsorb VOCs, gases, and unpleasant odors.

However, one question I get asked frequently is: What exactly are VOCs and odors?

In simple terms, these are gases, sometimes created by our daily activities, sometimes by external sources, that can be harmful to your health. Because of that, it’s important to understand and be aware of them.

What Are VOCs?

VOCs, or Volatile Organic Compounds, are gases released from solid or liquid products. These gases easily evaporate at room temperature and mix with indoor air.

The problem is that VOCs are usually invisible. To detect them accurately, you need a specialized device for monitoring air quality, such as an air quality monitor.

Some VOCs have a noticeable smell, so you might suspect elevated VOC levels in your home. However, most VOCs are completely odorless while still being potentially harmful.

Common indoor sources of VOCs include:

• Cleaning products and disinfectants: Using strong chemicals in bathrooms, kitchens, or other rooms can significantly increase VOC levels.
• Air fresheners and scented candles: Well-known sources of indoor VOC pollution.
• Furniture, flooring, and pressed wood (MDF, particleboard): That “new furniture smell” is often formaldehyde, a gas that can be harmful to your health.
• Personal care products (perfumes, deodorants, hairspray): These products frequently trigger air quality monitors, especially those with VOC readings.
• Cooking (especially frying and gas stoves): One of the main sources of indoor air pollution in most homes.

Modern homes, especially those without proper ventilation, air purifiers, or air-exchange systems, often trap VOCs indoors. Over time, prolonged exposure can negatively affect your health.

What Are Odors?

Odors, on the other hand, are smells you can easily detect. They aren’t always harmful; sometimes they smell pleasant, sometimes unpleasant.

Odors are often caused by VOCs, but not all odors are dangerous.

Typical sources of indoor odors include cooking smells, pets and litter boxes, garbage and food waste, mold and mildew, tobacco smoke, and similar pollutants.

While odors can be unpleasant, their presence doesn’t automatically mean the air is unsafe. In many cases, persistent odors are simply a result of poor ventilation.

Final Thoughts

Being aware of your indoor air quality is important, and it’s also worth noting that we are often the main source of VOCs and odors in our homes.

The most common indoor contributors are cooking, cigarette smoke, and mold.

Awareness is always the first step toward solving a problem. Simply knowing that VOCs are present in your home is a good start.

Even simple solutions, like opening windows regularly, can significantly help prevent VOCs and unpleasant odors from staying indoors for long periods.
