Shopping for paint has never come with more buzzwords. Eco-friendly paint. Earth-friendly paint. Non-toxic paint. Low VOC. Zero VOC. It feels like every paint can promises you healthier air, but what do those labels really mean? 

The truth is, there's a real difference between what is low VOC paint and what is zero VOC paint and understanding it can help you make a smarter choice for your home. 

The biggest distinction isn't just meeting regulations; it's about how much your paint may continue to release chemicals into your indoor air after you've finished painting. And thanks to a little-known tinting loophole, some paints marketed as "zero VOC" aren't always as zero as they seem. 

Here's everything you need to know before choosing your next gallon. 

Why VOC Levels Matter 

VOC stands for volatile organic compounds which are chemicals that evaporate into the air as paint dries and cures. They're responsible for much of that "fresh paint smell," but the smell isn't the only concern. 

High levels of VOCs can contribute to indoor air pollution and may trigger VOC exposure symptoms, including: 

-Headaches 

-Dizziness 

-Eye, nose or throat irritation 

-Nausea 

-Respiratory irritation 

-Worsening asthma symptoms in sensitive individuals 

While traditional paints can continue off-gassing for weeks (or even months), modern low-emission paints dramatically reduce those emissions. 

That's why many homeowners now look for non-toxic paint, eco-friendly paint or earth-friendly paint options that improve indoor air quality without sacrificing beautiful color. 

What Is Low VOC Paint? 

If you've ever wondered what is low VOC paint, here's the simple answer: 

Low VOC paint contains a reduced amount of volatile organic compounds compared to traditional paint. 

Under U.S. regulations, most interior low VOC paint contains: 

-Flat paints: less than 50 grams of VOCs per liter (g/L) 

-Non-flat paints: less than 150 g/L 

That's significantly lower than older paint formulations, making low VOC paint a healthier choice for most homes. 

While low VOC paints still release some emissions during drying and curing, those levels are much lower than conventional paints. 

What Is Zero VOC Paint? 

Despite the name, zero VOC paint isn't always literally zero. 

According to FTC guidance, manufacturers may label paint as "zero VOC" when it contains only trace amounts of VOCs—typically less than 5 g/L in the untinted base paint. 

In other words: 

-It contains little to no measurable VOCs before color is added. 

-It dramatically reduces indoor emissions compared to traditional paints. 

-It still must meet strict manufacturing standards. 

The result is one of the lowest-emission paint options available for residential interiors. 

Zero VOC Paint vs Low VOC Paint: Key Differences 

VOC Limits 

Off-Gassing 

Both options produce far less off-gassing than traditional paints. 

However, zero VOC paint generally releases fewer airborne chemicals during application and curing, making it especially appealing for occupied homes. 

Performance and Cost 

Years ago, low-emission paints sometimes sacrificed durability or coverage. 

Today, premium formulations (including our GREENGUARD Gold certified paint) deliver: 

-Excellent hide 

-Rich color 

-Smooth application 

-Outstanding durability 

-Easy cleaning 

Zero VOC paints may cost slightly more than some low VOC options, but many homeowners consider the healthier indoor air benefits well worth it. 

The Colorant Loophole Explained 

Here's the part many paint labels don't mention. 

A paint base may technically qualify as zero VOC, but once colorants are added at the paint counter, those tints can introduce additional VOCs. 

This means: 

-The untinted base is zero VOC. 

-The finished colored paint may no longer technically remain zero VOC. 

-Some manufacturers have reformulated their colorants to maintain extremely low VOC levels across virtually every color, while others have not. 

That's why reading beyond the front label matters. 

Which Paint Is Best for Your Home? 

Nurseries and Bedrooms 

Bedrooms are where we spend a significant portion of our lives. 

Choosing zero VOC paint or GREENGUARD Gold certified paint helps minimize indoor emissions, making these spaces more comfortable shortly after painting. 

For nurseries, many parents prioritize the lowest-emission products available because babies breathe more air relative to their body size than adults. 

Pregnancy and Sensitive Households 

Many people prefer minimizing unnecessary chemical exposure during pregnancy. 

While no paint can be guaranteed completely exposure-free, selecting low-emission paint, ensuring good ventilation and allowing adequate drying time are common precautions. 

Households with chemical sensitivities may also appreciate paints with the lowest available VOC emissions. 

Asthma and Allergies 

People with asthma or respiratory sensitivities often benefit from paints designed to reduce indoor air pollutants. 

While paint won't prevent allergies, choosing lower-emission products may help reduce one potential source of indoor irritation. 

Common Questions About Zero VOC and Low VOC Paint 

Why Can Zero VOC Paint Still Smell? 

A paint smell doesn't necessarily mean VOCs. 

Modern paints contain many ingredients besides VOCs, including water, binders, minerals, and additives. These ingredients can create a noticeable odor even when VOC levels are extremely low. 

The smell usually fades as the paint cures. 

Do Paint Colors Affect VOC Levels? 

Sometimes. 

As mentioned earlier, certain colorants can add VOCs during tinting. 

This is why not every color in every paint line remains technically zero VOC after mixing. 

Manufacturers that use low- or zero-VOC colorants help minimize this issue. 

What to Look for on a Paint Label 

Rather than relying on marketing phrases alone, check for: 

Clearly stated VOC content (g/L) 

Zero VOC or low VOC disclosure 

Third-party indoor air certifications 

Transparent product documentation 

Information about tinted VOC levels when available 

Terms like non-toxic paint and eco-friendly paint can be helpful, but they're not regulated definitions on their own. 

The most meaningful information comes from measurable VOC data and independent certifications. 

Why GREENGUARD Gold Certification Matters 

Not all low-emission paints are tested the same way. 

GREENGUARD Gold certified paint undergoes independent testing for low chemical emissions to help meet some of the world's most rigorous indoor air quality standards. 

The certification evaluates how much a finished product emits into indoor air—not just what goes into the can. 

That's especially valuable for: 

Schools 

Healthcare settings 

Nurseries 

Bedrooms 

Homes where indoor air quality is a priority 

It provides additional confidence beyond simple marketing claims. 

Choosing the Right Low Emission Paint 

Whether you choose low VOC or zero VOC paint, you're already making a healthier choice than traditional high-VOC paints. 

If you're looking for the lowest possible indoor emissions—especially for bedrooms, nurseries or frequently occupied spaces—zero VOC paints paired with independent certifications offer added peace of mind.

People Also Ask 

Is zero VOC paint really VOC free? 

Not always. Most zero VOC paints contain less than 5 g/L of VOCs in the untinted base. In some cases, adding colorants during tinting can introduce small amounts of VOCs. 

How much VOC in paint is considered low-VOC? 

Generally, low VOC interior paint contains less than 50 g/L for flat finishes and less than 150 g/L for non-flat finishes. To know if a paint is truly low or zero VOC, look for a clearly stated VOC number, zero-VOC colorants and a certification that proves it lives up to the claim. 

Can you sleep in a room with zero VOC paint? 

Many people can use a room sooner after painting with zero VOC products, but it's still best to allow the paint to dry completely and keep the space well ventilated according to the manufacturer's instructions. 

Does zero VOC paint perform differently than low VOC paint? 

Not necessarily. Modern premium formulations offer excellent durability, coverage and washability regardless of whether they're labeled low VOC or zero VOC. 

Why does zero VOC paint sometimes still have a paint smell? 

Odor can come from ingredients other than VOCs. Even paints with extremely low emissions may have a temporary smell while drying. 

Is zero VOC paint worth the extra cost compared to low VOC paint? 

For many homeowners, especially those painting bedrooms, nurseries or frequently occupied rooms, the lower emissions and added peace of mind make the investment worthwhile. 

Which is better for people with allergies, asthma, or chemical sensitivities: zero VOC or low VOC? 

Zero VOC paints generally produce fewer emissions, making them a popular choice for people looking to minimize indoor air pollutants. Choosing products with independent certifications like GREENGUARD Gold provides additional assurance. 

Do paint colors affect whether a paint remains zero VOC or low VOC? 

Yes. Some paint colorants can introduce VOCs during tinting. Manufacturers that use low-emission colorants help maintain lower VOC levels across a broader range of colors.
