Mold Scanner vs Airthings Wave Mini
The Airthings Wave Mini is an air monitor that runs about $80 and predicts mold risk from temperature and humidity. It does not detect mold or spores. Mold Scanner runs a guided whole-home walkthrough from your phone, screens visible surfaces for likely mold, and returns a structured report with likely type, water source, liability notes, and cleaning and PPE guidance, plus a PDF evidence log. They pair well: use the Wave Mini to monitor humidity over time, and Mold Scanner to screen surfaces and document what you find.
The short version
These two tools do not really compete, because they measure different things. The Airthings Wave Mini watches temperature and humidity and predicts when conditions favor mold. It is a monitor, not a detector, so it never tells you whether mold is actually there. Mold Scanner screens the surfaces themselves, room by room, and hands you a report on what it sees.
Neither is a full inspection. A sensor predicts risk, a phone screen reads visible surfaces, and a visual-only check catches roughly 30 to 50% of real contamination because so much mold hides where no camera reaches. The right choice comes down to whether you want to monitor conditions over time or screen for existing mold today.

Predicting risk vs screening surfaces
This is the core difference. The Wave Mini is good at the thing it does: it watches humidity and temperature and warns you when conditions tip into the range mold likes. That is genuinely useful for prevention, because mold needs moisture to grow. What it cannot do is tell you whether mold is already there. It reads the air around a surface, never the surface itself.
Mold Scanner is built for the other half of the problem. Instead of monitoring conditions, it guides you through a room-by-room screen of the surfaces, so you check the spots a professional inspector would. A sensor says the bathroom is humid. The scanner looks at the bathroom and screens whether the grout, ceiling, and caulk show likely mold.
The report you get
A sensor gives you a humidity reading and a risk light. Useful for habits, but it stops there. Mold Scanner returns a structured report: the likely mold type, the likely water source feeding it, liability notes for renters and owners, and cleaning and PPE guidance you can act on. You also get a PDF evidence log.
That evidence log matters more than it sounds. If you are a renter documenting a problem for a landlord, or a buyer flagging an issue before closing, a dated report you can hand over is far stronger than a screenshot of a humidity graph. It turns a phone scan into something you can use in a conversation that has money on the line.
Price and honest framing
On price, the Airthings Wave Mini is a one-time hardware buy at about $80 that keeps monitoring as long as it runs. Mold Scanner is pre-launch, so today the way in is the waitlist at moldscanner.ai.
On framing, one honest note for both. A humidity sensor predicts risk and a phone screen reads visible surfaces, and neither is a full inspection or a medical result. Mold Scanner says this plainly: it is a screening tool, it makes no health claims, and it tells you it cannot see hidden mold inside walls, ducts, or subfloors. For symptoms, see a qualified physician. For high-stakes property, confirm with a lab sample or a licensed inspector.
Which one to pick
You want to monitor humidity and prevent mold over time
You want a sensor in the room that tracks temperature and humidity and warns you when conditions favor mold. That is a strong prevention tool. Just remember it predicts risk from conditions, it does not tell you whether mold is already present.
You want to screen surfaces and walk away with a report
You want to know whether mold is actually there, not just whether conditions favor it. You want a guided room-by-room screen, a structured report with the likely water source and cleaning and PPE guidance, and a PDF evidence log you can hand to a landlord, contractor, or inspector. It is a screening tool, not a diagnosis. Join the waitlist for first access.
These two pair well rather than compete: a sensor to keep humidity in check, a scanner to screen the surfaces when you suspect a problem. Whichever you start with, confirm anything serious with a lab sample or a licensed inspector.
Screen your whole home, not just one spot
Mold Scanner walks you through the spots a professional inspector checks and gives you a structured report with cleaning and PPE guidance. Join the waitlist for first access.

What is the difference between Mold Scanner and Airthings Wave Mini?
The Airthings Wave Mini is a hardware air monitor that tracks temperature and humidity and predicts mold risk from those readings. It does not detect mold or spores. Mold Scanner runs a guided whole-home walkthrough from your phone and screens visible surfaces for likely mold, then returns a structured report with likely type, the likely water source, liability notes, and cleaning and PPE guidance, plus a PDF evidence log. The main difference is a sensor that predicts risk from conditions versus a tool that screens the surfaces themselves.
Does the Airthings Wave Mini detect mold?
No. The Wave Mini is an air monitor that measures temperature, humidity, and air quality, and it uses humidity and temperature to predict mold risk. It does not detect mold growth and it does not detect spores. It tells you when conditions favor mold, not whether mold is present.
How much does the Airthings Wave Mini cost?
The Airthings Wave Mini is hardware that runs about $80. It is a one-time purchase that sits in a room and tracks conditions over time. Mold Scanner is pre-launch, so the way to access it today is the waitlist at moldscanner.ai.
Which should I use, Mold Scanner or Airthings Wave Mini?
They pair well rather than compete. The Wave Mini is good for monitoring humidity over time so you can keep conditions below the level mold likes. Mold Scanner is for when you want to screen surfaces and find existing mold, room by room, with a report you can show a landlord, contractor, or inspector. Use the sensor to prevent, and the scanner to screen.
Can either replace a professional mold inspection?
No. A humidity sensor predicts risk and a phone screen reads visible surfaces, but neither sees hidden mold inside walls, ducts, or under flooring. A professional inspection averages about $670 and can find hidden mold and sample the air. Use a sensor to monitor and a scanner to screen, then bring in a pro or a lab for anything serious or high-stakes.
