It’s worth testing for if…
- A room smells of chemicals, new furniture or fuel
- You have an attached garage, or a workshop in the house
- Symptoms improve when you leave the building
What is in your air?
25 measurements
Indoor air concentrates whatever the building and its contents release. Solvents and fuel compounds come in from an attached garage, a workshop, stored paint and cleaning products; other VOCs off-gas from new furniture, flooring adhesives and pressed wood. Because a modern house is built to be airtight, these accumulate rather than dispersing — indoor concentrations of many VOCs run several times higher than outdoor air on the same street. The badge samples continuously over its exposure period, which catches the average rather than the moment you happened to test.
How to Test
Unclip the badge, leave it out in the room you want tested, and seal it back in its pouch when the time on the card is up. Nothing to plug in, nothing to run.
Supports concern around
The brain and nervous system, short-term toxic effects at high doses, fertility and reproduction, cancer, development in children.
23 of the 25 substances this kit measures have a hazard classification on file. The other 2 do not yet — which means nothing has been established about them either way.
Every measurement, explained
At Nestwell, we provide science backed ranges for all the exposures in your home, allowing for personalized suggestions of in home remediation.

“Detects to” is the method detection limit — the lowest concentration this kit's method can distinguish from zero. The lab may substitute an equivalent or updated method, in which case its limit may differ from the one shown.
What these substances are linked to
Health effects that researchers have associated with the substances on this panel, from the EPA's CompTox database. This describes the substances themselves — not your home. Whether any of them are present, and at what level, is what the test is for.
- The brain and nervous system23 of the 23 classified substances on this panel — including Benzene, Chloroform and Tetrachloroethylene
- Short-term toxic effects at high doses18 of the 23 classified substances on this panel — including Benzene, Chloroform and Tetrachloroethylene
- Fertility and reproduction16 of the 23 classified substances on this panel — including Benzene, Chloroform and Tetrachloroethylene
- Cancer11 of the 23 classified substances on this panel — including Benzene, Chloroform and Tetrachloroethylene
- Development in children7 of the 23 classified substances on this panel — including Chloroform, Tetrachloroethylene and Toluene
23 of the 25 substances this kit measures have a hazard classification on file. The other 2 do not yet — which means nothing has been established about them either way. A classification means a substance has been associated with an effect in published research — usually at doses well above what a home test would find. It is not a diagnosis, and it is not a prediction.
Designed To Understand Your Whole House
A single kit answers one question properly rather than several vaguely. Whichever you start with, it is the same lab, the same methods, and the same reporting — so results from one kit sit beside results from the next, in one place, on the same scale.
Accredited labs, regulatory methods
Every sample is analyzed by an accredited environmental lab with the same methods regulatory testing uses.
Numbers with regulatory context
Results come back as a measured value next to the standard it is judged against, not just a "detected".
One box, no home visit
Everything arrives at once and we tell you both where and how to sample, no outside home inspection needed.
How Nestwell Testing Works
How Collection Works
Collect
Unclip the badge, leave it out in the room you want tested, and seal it back in its pouch when the time on the card is up. Nothing to plug in, nothing to run.
Mail
Everything goes back in the same box with the prepaid return label. No appointment, nobody in your house, and easy to send back when convenient for you.
Read
Results land in your Nestwell dashboard in about 10 days, each scored against the standard that applies to it.
Why Nestwell?
| Capability | Nestwell | Hardware Store Strips | In Person Inspector |
|---|---|---|---|
| Samples from across your home | Yes | One sample, one place | Yes |
| Real exposure concentrations | Yes | Paper colour key | Sometimes |
| Accredited lab, regulatory methods | Yes | No | Sometimes |
| Nobody has to come into your home | Yes | Yes | No |
| Results tracked over time in one place | Yes | No | One time result |
A number is only useful next to its limit.
At Nestwell, we provide science backed ranges for all the exposures in your home, allowing for personalized suggestions of in home remediation.
Accredited labs only
Samples are analysed by accredited environmental laboratories using the analytical methods used for regulatory compliance work: the same reading a professional consultant would order.
Each result has a standard
A number on its own is not an answer. The EPA action level for lead in water is 15 ppb; the CDC states there is no safe level of lead exposure for children. Each finding is shown against the limit that applies to it.
Where there is no limit, we say so
The EPA sets no numeric limit for mold, and moisture control is the real remedy. Mold results are reported as what is growing and at what relative level, never as just a pass or a fail.

“Our physical & home environment is a direct determinant of our health, and is immunoregulatory. In a year, we breathe about 6 million times, drink 250 gallons of liquid, and eat almost 2 tons of food, with hundreds of compounds interacting on our skin and immune systems. Small environmental changes make a big difference, especially in early childhood development and for vulnerable adults.”
Frequently Asked Questions
Have questions? Find answers to common customer concerns below.
What does the VOC Air Exposure Test actually measure?
The panel runs 25 measures, covering Volatile organic compounds (VOCs), Fuel and petroleum compounds, Other organic compounds and Disinfection byproducts. Every one is listed on this page with its detection limit, so you can check for a specific substance before you buy.
How do I take the sample?
Unclip the badge, leave it out in the room you want tested, and seal it back in its pouch when the time on the card is up. Nothing to plug in, nothing to run. It takes minutes to set out, then it sits, and everything you need comes in the box.
How long until I get results?
The kit reaches you in about 3 days. Once the lab receives your sample, results appear in your Nestwell account in about 10 days. Return shipping is prepaid and included.
Who analyses the sample?
An accredited environmental laboratory, using published analytical methods — the same methods and the same labs used for regulatory and commercial testing. Nestwell does not run the analysis itself.
Why do some substances on the panel have explanations and others do not?
Our advisors have written up 14 of the 25 measures on this panel so far. The rest are still measured, reported and held to the same detection limits — they are listed under "Also measured" until the write-up exists. We would rather show you the gap than fill it with something we have not checked.
What happens if something comes back high?
Your results are shown against the relevant reference values rather than as a bare number, so you can see which measures stand out and by how much. The lab reports what it measured; it does not diagnose, and a lab result is not medical advice.
Can I pay with an HSA or FSA?
Most Nestwell kits are HSA/FSA eligible through Truemed. Eligibility is shown on the kit page at checkout, and where it applies you can pay with pre-tax dollars.
