Paint. Furniture. Cleaning products. Air fresheners. Flooring. Even some personal care products.
Many of the items we use every day can release gases into the air known as volatile organic compounds (VOCs). While the term “VOC” often sounds alarming, the reality is more nuanced. VOCs represent a large group of chemicals with different properties, different uses, and different levels of potential concern.
The goal of this guide is not to eliminate every VOC from your home—an unrealistic objective—but rather to help you understand where VOCs come from, when they are most likely to be present, and practical steps you can take to reduce unnecessary exposure while creating a healthier indoor environment.
Part of the Air Quality Series
This article is part of the Air Quality Guide, which explores indoor pollutants, ventilation, filtration, humidity control, and practical strategies for creating healthier indoor air.
Key Takeaways
✓ VOCs are gases released from many common household products and building materials.
✓ Indoor VOC concentrations are often higher than outdoor levels because homes are more enclosed.
✓ Newly manufactured products generally release the highest levels during the first weeks or months after installation.
✓ Improving ventilation and choosing lower-VOC products when practical can help reduce exposure.
✓ Low-toxin living is about making informed, sustainable choices—not striving for perfection.
What Are VOCs?
Volatile Organic Compounds (VOCs) are carbon-based chemicals that readily evaporate into the air at room temperature. The word “volatile” simply means these compounds easily become gases. Many VOCs are intentionally used because they improve how products perform. For example, they may help paint spread smoothly, adhesives bond materials, cleaning products dissolve dirt, or fragrances create a particular scent. Because VOCs evaporate into the air, they become part of the indoor environment where people live, work, sleep, and recover. Importantly, not all VOCs are the same. Thousands of different VOCs exist, each with unique chemical properties. Some dissipate quickly after a product is opened or installed, while others may continue to off-gas at lower levels over time.
Why Do VOCs Matter?
Most people think about outdoor pollution when considering air quality. However, indoor environments often contain a variety of VOC sources that can contribute to overall indoor air quality.
Factors that influence indoor VOC levels include:
- The number of VOC-emitting products in the home
- Ventilation
- Temperature
- Humidity
- Building materials
- Recent renovations
- Household habits
New homes or recently remodeled spaces frequently have higher VOC levels because fresh paint, flooring, cabinetry, furniture, and adhesives may continue releasing gases for a period after installation.
For many homeowners, awareness—not fear—is the most valuable first step.
GroLifeHealth Perspective
One observation I’ve made throughout my healthcare career is that many people assume improving indoor air quality requires purchasing expensive equipment.
In reality, some of the biggest improvements come from understanding where pollutants originate and making thoughtful, gradual changes over time. Simple habits—such as improving ventilation after painting, allowing new furniture to air out, or choosing lower-VOC products when replacing existing items—can often have a meaningful impact without dramatically increasing cost.
The GroLifeHealth VOC Framework
Reducing unnecessary VOC exposure doesn’t require replacing everything in your home. Instead, GroLifeHealth recommends a practical five-step framework.
1. Identify
Recognize the products and materials in your home that may release VOCs.
2. Prioritize
Focus first on areas where exposure is likely to be greatest, such as recent renovations or heavily scented products used every day.
3. Ventilate
Increase fresh air exchange whenever practical, especially after introducing new products into your home.
4. Replace Gradually
As products naturally wear out, consider lower-VOC alternatives that align with your budget and priorities.
5. Maintain
Continue building healthier habits through informed purchasing decisions, routine ventilation, and ongoing attention to indoor air quality.
Where Are VOCs Commonly Found?
Understanding where VOCs are commonly encountered helps homeowners prioritize improvements.
Living Room
Potential sources include:
- Upholstered furniture
- Carpeting
- Area rugs
- Paint
- Electronics
- Air fresheners
Practical Takeaway
If you’ve recently purchased new furniture, allowing it to air out in a well-ventilated space before extended indoor use may help reduce initial off-gassing.
Kitchen
Potential sources include:
- Cabinets
- Composite wood products
- Cleaning products
- Flooring
- Adhesives
- Air fresheners
Kitchen ventilation serves multiple purposes by helping remove cooking-related pollutants while also improving overall air exchange.
Bedroom
Potential sources include:
- Mattresses
- Upholstered headboards
- Bedding treatments
- Air fresheners
- Furniture
Because people spend many hours sleeping, maintaining good ventilation and minimizing unnecessary fragrance products may contribute to a healthier sleep environment.

Bathroom
Potential sources include:
- Personal care products
- Hair sprays
- Nail polish
- Cleaning products
- Air fresheners
Bathrooms often contain numerous products used daily, making them a practical place to simplify routines and evaluate ingredient choices.
Garage and Storage Areas
Potential sources include:
- Paint
- Solvents
- Fuel containers
- Adhesives
- Automotive products
Whenever possible, products that emit strong chemical odors should be stored outside the primary living space in accordance with manufacturer recommendations.
GroLifeHealth Practical Takeaway
Many homeowners feel overwhelmed when learning about VOCs because the number of potential sources seems endless.
Rather than trying to replace everything at once, start by identifying the products you use most frequently. When those products need replacing, consider whether a lower-VOC alternative meets your needs. Over time, these small decisions can collectively reduce unnecessary indoor exposures while remaining practical and affordable.
How to Reduce VOC Exposure
The good news is that reducing unnecessary VOC exposure doesn’t require replacing everything in your home overnight. In many cases, simple changes in purchasing habits, ventilation, and home maintenance can make a meaningful difference.
Rather than trying to eliminate every possible source, focus on the changes that offer the greatest benefit while fitting your lifestyle and budget.
Some indoor air quality monitors include sensors that estimate VOC levels. While consumer monitors are not laboratory instruments, they can help identify changes in indoor air after activities such as painting, cleaning, or bringing new furniture into your home.
Air Quality Monitors Explained
Prioritize Ventilation
Fresh air exchange is one of the simplest ways to reduce indoor VOC concentrations.
Whenever practical:
- Open windows during favorable weather.
- Use kitchen range hoods while cooking.
- Run bathroom exhaust fans during and after showers.
- Increase ventilation after painting or bringing new furniture into the home.
Homes that are tightly sealed for energy efficiency may benefit even more from intentional ventilation strategies.
Practical Takeaway
If you’ve recently painted a room or purchased new furniture, increase ventilation for several days afterward. This is often when off-gassing is greatest.
Choose Lower-VOC Products When Replacing Items
You don’t need to throw away products that are already serving their purpose.
Instead, as items naturally wear out, consider replacing them with lower-VOC alternatives when practical.
Examples include:
- Interior paints
- Flooring
- Cabinets
- Adhesives
- Furniture
- Cleaning products
Making gradual changes often feels more realistic and sustainable than attempting a complete home makeover.
Now that you understand the most common indoor air pollutants, the next step is learning how to reduce them through practical improvements around your home.
How to Improve Indoor Air Quality Naturally
Reduce Unnecessary Fragrances
Many people enjoy scented candles, air fresheners, and fragranced cleaning products. However, heavily scented products can contribute additional chemicals to the indoor environment.
Consider alternatives such as:
- Improving ventilation
- Identifying and addressing odor sources directly
- Choosing fragrance-free products when appropriate
- Using products only as directed
The goal isn’t to eliminate all scented products but to use them intentionally.
Store Household Chemicals Properly
Products such as paint, solvents, fuels, pesticides, and automotive supplies should be stored according to manufacturer recommendations and, whenever possible, outside primary living areas.
Garages, detached sheds, or well-ventilated storage spaces are generally preferable to closets or living spaces.
Maintain Good Indoor Air Quality
Reducing VOC exposure works best as part of an overall indoor air quality strategy.
This includes:
- Replacing HVAC filters regularly
- Controlling indoor humidity
- Addressing moisture problems promptly
- Cleaning dust-prone areas
- Maintaining adequate ventilation
VOCs are only one component of indoor air quality. A healthy home considers multiple environmental factors together.
When Are VOC Levels Often Highest?
VOC concentrations are often elevated during specific situations rather than remaining constant over time.
Examples include:
After Painting
Fresh paint commonly releases VOCs as it dries and cures.
During Home Renovations
Installing flooring, cabinetry, adhesives, insulation, or new building materials may temporarily increase indoor VOC levels.
New Furniture
Some manufactured furniture, mattresses, and upholstered products may release VOCs after purchase.
Heavy Cleaning
Using multiple cleaning products in a poorly ventilated space may temporarily increase airborne chemicals.
Understanding these situations helps homeowners take practical steps to improve ventilation when it matters most.
DNP Insight
One of the questions I hear most often is, “Should I replace everything in my home?”
For most people, the answer is no.
Healthier homes are usually built through thoughtful, gradual decisions rather than expensive overhauls. Prioritize the products you use most often, improve ventilation during high-exposure activities, and make informed purchasing decisions over time. Those habits are generally more sustainable—and more realistic—than striving for perfection.
Common Myths About VOCs
Myth
“If a product smells strong, it’s automatically dangerous.”
Fact
A strong odor does not necessarily indicate greater health risk, and some VOCs have little or no noticeable smell. Odor alone isn’t a reliable indicator.
Myth
“Natural products never contain VOCs.”
Fact
Many naturally occurring substances also release volatile organic compounds. The term “VOC” describes how a compound behaves, not whether it is natural or synthetic.
Myth
“You need to replace everything in your home.”
Fact
Most homeowners benefit more from making gradual improvements than attempting a complete replacement of household products.
Myth
“An air purifier removes every VOC.”
Fact
Some air purifiers are designed to help reduce certain airborne chemicals, particularly those that include activated carbon filtration. However, performance varies by product and pollutant, and source control and ventilation remain important components of a healthy indoor environment.
