Há compostos orgânicos voláteis (COV) na sua casa? Veja como saber com certeza
✓ Sua preocupação é compreensível. Os compostos orgânicos voláteis (COV): uma realidade mais comum do que a maioria imagina, e você faz bem em se informar.
Você não está exagerando. Este perigo é invisível e inodoro — a EPA recomenda que todo proprietário faça o teste, independentemente da idade ou do estado da casa.
O kit de teste abaixo pode dizer em 48 horas se sua casa tem níveis elevados. O teste é a única forma de saber com certeza.Detalhes (em inglês): as informações técnicas detalhadas abaixo permanecem em inglês.
Volatile Organic Compounds (VOCs) is a high-severity indoor air quality hazard that the EPA classifies as a significant health risk. It is most commonly found in kitchen, bathroom, garage and originates from paints and varnishes, cleaning supplies, air fresheners.
VOCs are emitted by paints, cleaning products, air fresheners, and building materials. Concentrations indoors are up to 10x higher than outdoors. Long-term exposure damages liver, kidneys, and the central nervous system.

Dados de referência rápida
| Hazard | Volatile Organic Compounds (VOCs) |
| EPA Severity | HIGH |
| Common Sources | paints and varnishes, cleaning supplies, air fresheners, paint strippers, dry-cleaned clothing, pesticides |
| Affected Areas | kitchen, bathroom, garage, home-office, laundry, nursery, dining-room, mudroom |
| Health Symptoms | headaches, dizziness, nausea, fatigue, eye and throat irritation, memory problems, skin reactions |
| EPA Recommendation | Use low-VOC or zero-VOC paints and products. Increase ventilation when using products containing VOCs. Store chemicals in well-ventilated areas or outside. Use air purifiers with activated carbon filters. |
Your Children Breathe 20,000 Liters of This Air Every Day
Kids breathe more air per pound of body weight than adults. Their lungs are still developing. If volatile organic compounds (vocs) is in your home, they're getting a higher dose than you are. You childproof cabinets and plug outlets — but have you checked what they're breathing?
⚠️ The EPA estimates indoor air can be 2–5× more polluted than outdoor air. Your family breathes 20,000 liters of indoor air every day.
If volatile organic compounds (vocs) is present, every breath could be doing damage you can't see or feel — until it's too late.

📋 Our Testing Methodology
Hazard severity classifications follow the EPA's Indoor Air Quality assessment framework:
- • Critical: Immediate health risk — evacuate and contact emergency services
- • High: Chronic exposure risk — test within 1 week, remediate within 30 days
- • Moderate: Potential risk — test to confirm, address if confirmed
Product recommendations are based on published detection accuracy, third-party test results, and EPA-recommended testing methods. Updated May 2026.

If your home has volatile organic compounds (vocs), there's a chance it also has formaldehyde (voc). Both can thrive in the same conditions. When you test for one, check for the others too.
Perigos relacionados
Formaldehyde (VOC)
Formaldehyde off-gases from pressed wood furniture, flooring, and new construction materials. It is classified as a known human carcinogen by the IARC. Levels are highest in new or recently renovated homes.
Paint Fumes and Off-Gassing
Fresh paint releases VOCs including formaldehyde, benzene, and toluene for weeks after application. Even low-VOC paints can off-gas for days. Children and pregnant women are most at risk.
Thirdhand Smoke Residue
Thirdhand smoke is the residual nicotine and chemicals left on surfaces by tobacco smoke. It clings to walls, furniture, and carpets for months. Reacts with indoor air to form carcinogenic compounds. Children are most vulnerable.
Poor Ventilation (Stale Air)
Modern energy-efficient homes trap pollutants indoors. Without adequate ventilation, CO2, VOCs, and airborne pathogens accumulate to levels 2-5x higher than outdoors. This is called sick building syndrome.
Comparação de os compostos orgânicos voláteis (COV) com perigos relacionados
Volatile Organic Compounds (VOCs) carries a HIGH severity rating — the second-highest tier. Compared to related indoor air hazards, 0 are rated more severe and 0 are rated lower. All demand attention, but the testing and remediation sequence depends on which hazards share your home's risk profile.
Both Volatile Organic Compounds (VOCs) and Formaldehyde (VOC) carry the same high severity classification. Their combined presence in your home creates a compounding effect that exceeds the risk of either alone. Both are commonly found in nursery, home office, kitchen. Addressing one without testing for the other leaves a blind spot in your home's air quality.
Shared locations: nursery, home office, kitchen, dining room, garage
Volatile Organic Compounds (VOCs) poses a higher immediate risk than Paint Fumes and Off-Gassing. While both require attention, volatile organic compounds (vocs) is classified as high severity versus paint fumes and off-gassing's moderate rating. If you test for one, the EPA recommends testing for the other simultaneously — they share common areas like nursery, kitchen, bathroom.

O que seus resultados do teste de os compostos orgânicos voláteis (COV) significam
After testing for volatile organic compounds (vocs), you'll receive a measurement or a positive/negative result. Here's how to interpret what that number means for your home and family.
Below Detection
No volatile organic compounds (vocs) was detected. Continue routine monitoring — high-severity hazards can emerge as conditions change.
What to do: Re-test every 6-12 months. Pay particular attention to paints and varnishes and cleaning supplies, which are the most common entry points.
Low-Level Detection
Low levels of volatile organic compounds (vocs) were detected. While not immediately dangerous, chronic exposure to a high-severity hazard compounds over time — especially in kitchen and bathroom.
What to do: Identify the source among: paints and varnishes, cleaning supplies, air fresheners. Improve ventilation and re-test in 2-4 weeks. Use low-VOC or zero-VOC paints and products.
Elevated / At Action Level
Volatile Organic Compounds (VOCs) levels have reached or exceeded the action threshold. At this level, the EPA recommends use low-voc or zero-voc paints and products.
What to do: Schedule professional testing within 1 week. Begin source remediation within 30 days. Do not ignore — high-severity hazards do not resolve on their own.
Interpretation guidelines are based on EPA standards for chemical hazards. For volatile organic compounds (vocs), use low-voc or zero-voc paints and products. Always confirm results with a certified professional.
Perguntas de proprietários sobre os compostos orgânicos voláteis (COV)
What are the symptoms of volatile organic compounds (vocs)?
Common symptoms of volatile organic compounds (vocs) include: headaches, dizziness, nausea, fatigue, eye and throat irritation, memory problems, skin reactions. If you are experiencing these symptoms, test your home and consult a healthcare provider.
How do I test my home for volatile organic compounds (vocs)?
Common sources include: paints and varnishes, cleaning supplies, air fresheners, paint strippers, dry-cleaned clothing, pesticides. You can test using the products recommended above. Use low-VOC or zero-VOC paints and products. Increase ventilation when using products containing VOCs. Store chemicals in well-ventilated areas or outside. Use air purifiers with activated carbon filters.
Is volatile organic compounds (vocs) dangerous to children?
Yes. Children are especially vulnerable to volatile organic compounds (vocs) because their respiratory systems are still developing and they breathe more air per pound of body weight than adults. VOCs are emitted by paints, cleaning products, air fresheners, and building materials. Concentrations indoors are up to 10x higher than outdoors. Long-term exposure damages liver, kidneys, and the central nervous system.
Stop wondering.
Start knowing.
The data is clear. The next step is testing.
The EPA notes that volatile organic compounds (vocs) can only be confirmed through testing — it's often invisible and odorless. A test kit or monitor gives you a real number instead of a guess.
