Introducing MARVIN Air

the world's first DIY mold monitoring device

MARVIN Air is ideal for renters, families, asthma sufferers, the elderly, and the health conscious.

  • 50% of US homes have hidden mold growth.
  • Infants exposed to mold have 3x chance of developing asthma.
  • Mold is a leading cause of death for the immunocompromised.

Like a canary in a coalmine, MARVIN Air can alert you of hidden mold growth before it begins to impact your health. Why spend up to $1000 for a mold inspector, and wait 5-7 days, when you can do it yourself powered by AI!


“MARVIN Labs helped me find problematic mold I would have otherwise never known about. Recommend!” – David Head

Simply place MARVIN Air in your home or office and MARVIN Air will collect airborne molds spores onto the provided test tray. Drop the test tray at any USPS letter box with the provided return paid envelope, and we’ll use our industry leading MARVIN Lens system to analyze for over a dozen toxic, and allergy causing molds.

Just 24-36 hours later you get a detailed report quantifying the levels of the specific mold growth in your home, an assessment of the risks to you and your family, and recommendations to resolve your mold issues. If you’re renting, send this report to your landlord or the city to come resolve the mold issues!

MARVIN Air also reports real-time air quality metrics including Carbon Monoxide, Particulate Matter (PM2.5 & PM10), Volatile Organic Compounds (VOCs), Optional Carbon Dioxide (CO2), Humidity, Pressure, and Temperature. Compared with other indoor air quality sensors, MARVIN Air has far greater sensing abilities, in a portable form-factor.

MARVIN Air test trays are analyzed by our in-house mold laboratory using the MARVIN Lens system, our industry leading tech that automates the American Society for Testing and Materials Standard test method (ASTM D7391-20) for identifying and quantifying airborne mold spores.

Used as best practice across the mold consulting industry, this standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

For piece of mind, every resulted generated by MARVIN Lens is also reviewed by our microbiology team. See more on our Mold Professionals page.
