Volatile Organic Compounds: Everything You Need to Know for a Healthier Home

Updated January 2026

Ever walked into a freshly painted room and noticed that distinct “new paint” smell? Or maybe you’ve opened a box of new furniture and caught a whiff of something a little off? That scent you’re noticing is often the presence of Volatile Organic Compounds, or VOCs for short.

Sounds a bit intimidating, doesn’t it? But don’t worry! While the name “Volatile Organic Compounds” might sound like something out of a science fiction movie, understanding what they are and where they come from is a huge step towards creating a healthier, happier home. Think of this as your friendly, no-jargon guide to becoming a VOC-savvy homeowner.

In this post, we’re going to break down everything you need to know about Volatile Organic Compounds: what they are, common sources in your home, their potential health impacts, and most importantly, simple, actionable steps you can take to reduce your exposure. Let’s get started on your journey to cleaner air!

What Exactly are Volatile Organic Compounds (VOCs)?

Let’s start with the basics. The “Volatile” part of Volatile Organic Compounds means they can easily evaporate or “off-gas” at room temperature. Think about how alcohol evaporates quickly from your skin – that’s volatility in action! The “Organic” part simply means they are carbon-based chemicals. These aren’t necessarily “organic” in the sense of organic food; it’s a chemistry term.

So, in simple terms, VOCs are a large group of carbon-based chemicals that easily become gases or vapours at typical indoor temperatures. Once airborne, they mix with the air we breathe. Many VOCs have a distinct odour, but importantly, many others are completely odourless, making them silent but potentially significant contributors to indoor air pollution.

The U.S. Environmental Protection Agency (EPA) defines VOCs as any organic compound that participates in atmospheric photochemical reactions, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate. While this technical definition is useful, for homeowners, it’s more about understanding their presence and impact.

Where Do Volatile Organic Compounds Come From in Our Homes?

This is where it gets interesting – and perhaps a little surprising. VOCs are incredibly common in our everyday lives, lurking in places you might not expect. Our modern homes are filled with products that contain and release them.

Let’s explore some of the biggest culprits:

1. Paints, Stains, and Finishes

This is probably the most well-known source. That “new paint smell” is almost entirely due to Volatile Organic Compounds off-gassing from solvents and additives used in paints, varnishes, and sealants. Even after the smell fades, these chemicals can continue to release into the air for months or even years.

2. Building Materials and Furnishings

Many materials used to construct and furnish our homes can be significant sources. This includes:

• Pressed Wood Products: Plywood, particleboard, and MDF (medium-density fiberboard) often use formaldehyde-based glues, with formaldehyde being a well-known VOC.

• New Carpeting: Adhesives, carpet backing, and even the fibers themselves can release VOCs.

• Vinyl Flooring: Can off-gas various chemicals.

• Upholstery and Mattresses: Flame retardants and other treatments can contain VOCs.

• Insulation: Some types of insulation can also contribute.

3. Cleaning Supplies

Ironically, many products designed to make our homes “clean” can introduce new pollutants. Common household cleaners, disinfectants, furniture polish, and even laundry detergents can contain various Volatile Organic Compounds. Look out for ingredients like ammonia, bleach, and fragrance chemicals.

4. Personal Care Products

Your bathroom cabinet might be a bigger source than you think! Hairsprays, perfumes, deodorants, nail polish, nail polish remover, and cosmetics often contain alcohols, phthalates, and other VOCs that get released when used.

5. Hobby Supplies and Craft Materials

If you’re a DIY enthusiast or have kids who love crafts, be mindful of:

• Adhesives and Glues: Many common glues contain powerful solvents.

• Markers and Paints: Especially solvent-based varieties.

• Photography Chemicals: Darkroom chemicals are potent sources.

• Art Supplies: Certain paints, thinners, and sprays used in art.

6. Office Equipment and Supplies

Even your workspace isn’t immune!

• Printers and Copiers: Can emit VOCs and ozone, especially during operation.

• Correction Fluids, Adhesives, Permanent Markers: Common office supplies.

• New Office Furniture: Just like home furnishings, desks and chairs can off-gas.

7. Outdoor Sources that Drift Indoors

While we focus on indoor sources, it’s worth noting that some VOCs can drift in from outside:

• Vehicle Exhaust: If you live near a busy road, VOCs from car emissions can enter through open windows.

• Pesticides and Herbicides: Used in gardens or nearby agricultural areas.

• Industrial Emissions: If you live near industrial zones.

As you can see, Volatile Organic Compounds are pretty ubiquitous! The key is not to panic, but to become aware and make informed choices.

Potential Health Impacts of Volatile Organic Compounds

Exposure to VOCs isn’t a one-size-fits-all situation. The health effects can vary widely depending on the type of VOC, the concentration in the air, the duration of exposure, and individual sensitivity. Some people might experience immediate, short-term reactions, while others might face long-term health concerns from chronic exposure.

Short-Term Effects (Acute Exposure):

For many people, especially those sensitive to chemicals, short-term exposure can lead to:

• Headaches

• Nausea and dizziness

• Eye, nose, and throat irritation

• Fatigue

• Loss of coordination

• Allergic skin reactions

• Exacerbation of asthma symptoms

These symptoms often resolve quickly once the source of the VOCs is removed or fresh air is introduced.

Long-Term Effects (Chronic Exposure):

Prolonged or repeated exposure to high levels of certain Volatile Organic Compounds is a more serious concern and has been linked to:

• Damage to the liver, kidney, and central nervous system

• Some types of cancer (e.g., formaldehyde is classified as a human carcinogen)

• Respiratory issues and chronic asthma

• Developmental or reproductive problems

It’s important to remember that not all VOCs are equally harmful, and research is ongoing. However, playing it safe by reducing your overall exposure is always a good strategy for improving your home’s air quality.

How to Reduce Volatile Organic Compounds in Your Home

Now for the good news! You have a lot of power to reduce VOCs and create a healthier indoor environment. Here are some actionable tips:

1. Prioritise Ventilation

This is your first line of defense!

• Open Windows and Doors Regularly: Even for 10-15 minutes a day, cross-ventilation flushes out stale air and replaces it with fresh air.

• Use Exhaust Fans: Always use kitchen range hoods and bathroom exhaust fans, especially during and after cooking or showering, to vent moisture and fumes outside.

• Ventilate During and After DIY Projects: When painting, gluing, or doing crafts, ensure maximum ventilation. Keep windows open and fans running for several days after the project is complete.

2. Choose Low-VOC or No-VOC Products

When buying new items for your home, make conscious choices:

• Paints: Look for paints, primers, and finishes labeled “Low-VOC” or “Zero-VOC.” Many reputable brands now offer these options.

• Flooring: Opt for solid wood, ceramic tile, or natural linoleum instead of conventional vinyl or synthetic carpeting if possible. If you choose carpet, ask about low-VOC options and adhesives.

• Furniture: Select solid wood furniture over pressed wood products (like particleboard or MDF), which often contain formaldehyde. If buying new pressed wood furniture, let it “off-gas” in a well-ventilated area (like a garage) for a few days or weeks before bringing it inside.

• Building Materials: When renovating, inquire about low-VOC options for insulation, adhesives, and sealants.

3. Smart Cleaning & Personal Care Choices

Rethink your everyday products:

• Natural Cleaners: Switch to eco-friendly, fragrance-free cleaning products or make your own using ingredients like vinegar, baking soda, and essential oils.

• Avoid Aerosols: Sprays release fine particles and VOCs into the air more easily.

• Read Labels: Look for certifications that indicate lower VOCs or fewer harmful chemicals in cleaning and personal care products.

• Limit Scents: Artificial fragrances in air fresheners, candles, and laundry products are significant sources of VOCs. Use essential oil diffusers or natural methods instead.

4. Store Products Safely

Proper storage prevents off-gassing into your living space:

• Seal Tightly: Keep all unused paints, solvents, adhesives, and cleaning products tightly sealed.

• Store Outdoors or in a Detached Garage: If possible, store these items in a shed or detached garage, rather than within your home, especially if you have a lot of them.

5. Introduce Air-Purifying Plants

While not a complete solution, certain houseplants can help filter some Volatile Organic Compounds from the air. Consider plants like:

• Snake Plants

• Spider Plants

• Peace Lilies

• Pothos

These green companions add beauty and a little extra air-cleaning power.

6. Consider an Air Purifier with Activated Carbon

While HEPA filters are great for particles (dust, dander), an air purifier equipped with an activated carbon filter is necessary to capture gaseous pollutants like VOCs. Activated carbon works by adsorbing these chemicals, trapping them within its porous structure. When choosing an air purifier, look for one that specifies VOC removal capabilities.

Monitoring Volatile Organic Compounds in Your Home

For those who want to take their air quality efforts to the next level, consider a home air quality monitor. Many modern devices can track real-time levels of various pollutants, including total VOCs (tVOCs), carbon dioxide, and particulate matter. This can provide valuable insights into which activities or products are affecting your home’s air the most.

For example, you might notice a spike in VOCs after using a certain cleaning spray or when new furniture arrives. This data empowers you to make more targeted adjustments and confirms that your efforts to reduce Volatile Organic Compounds are working!

Final Thoughts: Taking Control of Your Indoor Air

The term “Volatile Organic Compounds” doesn’t have to be scary. Instead, think of it as a helpful category that guides you toward smarter choices for your home and health. By understanding where these chemicals come from and implementing simple strategies like improved ventilation, choosing low-VOC products, and opting for natural alternatives, you can significantly reduce your exposure.

Your home should be a sanctuary, a place where you can relax and breathe easily. Taking control of your indoor air quality is one of the most proactive steps you can take for your well-being and the health of your family.

A Deep Dive: Which Volatile Organic Compounds Are in Your Home?

It can be overwhelming to look at a list of chemical names, but understanding which Volatile Organic Compounds are linked to specific items helps you make better choices. Furthermore, seeing how often these chemicals overlap shows why focusing on a few key areas—like your cleaning cabinet or your furniture choices—can make such a massive impact.

Here is a breakdown of common household chemicals and where they are most frequently hiding:

1. Building Materials & “Big” Furnishings

These are often the primary sources of long-term off-gassing because they are large and stay in your home for years.

2. Cleaning & Maintenance Products

In addition to building materials, the products we use to keep our homes tidy often release a sudden “spike” of Volatile Organic Compounds into the air.

• Ammonia: Found in window cleaners, floor waxes, and synthetic textiles. It has a very sharp, recognizable scent.

• Acetone & Benzene: Frequently used in heavy-duty paint removers, varnish removers, and strong detergents.

• Ethyl Alcohol: A primary ingredient in many liquid dish soaps, polishes, and general-purpose cleaning detergents.

• Chloroform: Surprisingly, this can be released into the air from chlorinated tap water, especially during a hot, steamy shower.

3. Personal Care & Beauty

We often forget that the things we put on our bodies also affect the air we breathe. To clarify, many of these chemicals are used as solvents or scents.

• Alcohols (Ethyl, Methyl, & Isopropyl): The base for perfumes, deodorants, shampoos, body washes, and hand sanitizers.

• Ethyl Acetate: The most common chemical found in nail varnish and nail polish remover.

• Toluene: Sometimes still found in nail polishes and hair sprays to help them dry quickly.

• Phthalates (Added): Often hidden under the word “Fragrance” on labels, these are common in perfumes and scented body products.

4. Combustion & Electronics

Finally, some Volatile Organic Compounds are produced by heat or electronic processes rather than just “leaking” out of a material.

• Butanal: This is released when you burn things. Think of scented candles, gas stoves, and even your backyard barbecue.

• Toluene & Xylene: Beyond just construction, these are used in the manufacturing of photocopiers and electrophotographic printers. If your home office feels “stuffy,” these might be the culprits!

Why Categorising Matters

On the other hand, you don’t need to memorise this entire list! Instead, focus on the “Hot Zones”:

1. The Bedroom: Focus on Formaldehyde (mattresses and wardrobes).

2. The Bathroom: Focus on Alcohols and Ethyl Acetate (beauty products).

3. The Kitchen: Focus on Butanal (cooking) and Ammonia (cleaning).

By understanding the specific Volatile Organic Compounds in these areas, you can strategically use the tips we discussed earlier—like opening a window while painting or switching to a fragrance-free shampoo—to create a cleaner, safer home.
