Lab-grade measurement of VOCs, fine particulates, CO2 and more.
Know exactly what you're breathing, and how to fix it.
Indoor air quality testing measures the pollutants inside your home: volatile organic compounds (VOCs), formaldehyde, fine particulate matter (PM2.5), carbon dioxide (CO2), carbon monoxide, humidity and common allergens. All Haven pairs calibrated, lab-grade monitors with accredited lab analysis and compares every result to EPA, WHO and ASHRAE guidance, so you know what is in your air and exactly what to do about it.
A complete picture of the air your family breathes, room by room.
Off-gassing from paint, furniture, flooring and cleaning products, measured down to parts per billion.
PM2.5 and PM10 from cooking, candles and wildfire smoke, small enough to reach deep into the lungs.
CO2 shows whether your home gets enough fresh air, especially in bedrooms overnight.
Moisture balance, combustion safety, and dust mite and pet allergen levels in one visit.
Book your assessment
Request a visit online or by phone. We'll ask about symptoms, your home and your goals so we test what matters.
On-site measurement
A certified inspector samples the air in key rooms with calibrated, lab-grade monitors and collects samples where needed.
Laboratory analysis
Samples go to an accredited lab. Every result is benchmarked against EPA, WHO and ASHRAE guidelines.

Of our lives are spent indoors, where most of our exposure to air pollutants happens.
Higher concentrations of some pollutants indoors than outdoors.
CO2 level at which researchers measured declines in decision-making performance.
Of current childhood asthma in the US is attributable to gas stove use.
If any of these sound familiar, an assessment gives you answers instead of guesses.
Headaches, congestion, fatigue or poor sleep that improve when you travel.
Fresh paint, cabinets, flooring and mattresses can off-gas VOCs for months.
Seattle's smoke seasons and busy roads push fine particles indoors.
Infants, older adults, and anyone with asthma or chemical sensitivities.
Our assessment measures VOCs, formaldehyde, PM2.5 and PM10, CO2, carbon monoxide, temperature and relative humidity, with allergen and mold spore sampling when needed. Each result is compared to EPA, WHO and ASHRAE guidance.
Pricing depends on the size of your home and how many rooms and tests you need. Request an assessment and we will send you a clear, fixed quote before anything is scheduled. No surprises.
Consumer monitors are great for spotting trends, but most use low-cost sensors that drift over time and can't identify specific VOCs or allergens. Professional testing uses calibrated equipment and accredited lab analysis, so you get results you can act on and share with your doctor.
Outdoor air is roughly 420 ppm. Indoor levels that stay under about 1,000 ppm are a common sign of adequate ventilation. Readings that stay higher, especially in bedrooms overnight, suggest your home needs more fresh air.
Yes. During smoke events, fine particles (PM2.5) easily get inside through gaps and ventilation. Testing shows how well your home holds up and whether upgrades like HEPA purifiers or MERV-13 filters are worth it.
No. Just like our mold inspections, we stay independent. Our recommendations are based only on your data, with no products to sell.
Air quality testing is launching across the Greater Seattle area. Join the priority list and we will reach out to schedule, or book a mold inspection today.
