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. Mold Scanner applies AI-assisted visual screening to the visible surfaces shown in submitted photos.
Neither is a full inspection. A sensor cannot establish whether mold is present, and a phone screen cannot see behind walls, under flooring, or inside ducts. The right choice comes down to whether you want to monitor conditions over time or run a first-pass visual screen of camera-visible surfaces.

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 handles a different task. Its 266 guided photo prompts cover visible surfaces across 19 rooms, with a 38-prompt Quick flow and a 129-prompt Standard flow. It screens only what the submitted photos show. It cannot measure humidity, locate a moisture source, see hidden growth, or confirm that mold is present.
The report you get
A sensor gives you humidity readings over time. Mold Scanner returns a local visual screening report that can show submitted photos, visible cues, camera limitations, and conservative next steps. The report stays on your device unless you export it.
The report is for reviewing a visual screen. It is not laboratory evidence, a legal or liability assessment, or proof that mold exists. Use an appropriate licensed professional or laboratory when documentation must support a high-stakes property decision.
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 a guided AI-assisted screen of visible surfaces across the home. The local report can show submitted photos, visible cues, camera limitations, and conservative next steps. It does not identify a water source or establish whether mold is present. 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.
Does Airthings detect mold?
No. The Airthings Wave Mini does not detect mold or spores. It reads temperature and humidity and flags conditions that favor mold, so it shows risk, not presence.
If you are wondering whether Airthings can find mold in a bathroom, closet, or basement, this is where the line falls.
What the Wave Mini can tell you
- The temperature and humidity in the room where it sits.
- A risk indicator that reflects whether those conditions favor mold.
- How those readings change over time in the app.
What it cannot tell you
- Whether mold is growing on a wall, ceiling, or floor.
- Whether spores are in the air.
- Whether mold is hiding behind a wall or under flooring.
The sensor reads the air around a surface, never the surface itself. That is true in Los Angeles or anywhere else. The reading depends on the room the sensor is in, not on the city.
A calm reading is good news about conditions. It is not proof that a surface is clean. If you can see a suspicious spot, a photo screen such as Mold Scanner checks the visible surface for signs of mold growth, and a lab sample or a licensed inspector should confirm anything serious.
Is the Airthings mold detector really a detector?
Not in the usual sense. The product people call an Airthings mold detector is the Wave Mini, an air monitor that predicts mold risk from temperature and humidity.
The name causes the confusion. Searches for Airthings mold usually mean the mold risk indicator on the Wave Mini. That indicator is an estimate built from conditions in the room. It is not a mold test result, and it does not say mold is present.
That does not make it a bad buy. Mold needs moisture to grow, and EPA guidance ties mold growth to moisture and humidity. A sensor that warns you when a room drifts into mold-friendly conditions helps you act before a problem starts.
Which tool answers which question
| Your question | Better fit |
|---|---|
| Is this room staying humid enough to favor mold? | Airthings Wave Mini, about $80 one time |
| Do these visible surfaces show signs of mold growth? | A photo screen such as Mold Scanner |
| Is mold hiding inside a wall, duct, or subfloor? | A licensed inspector or lab |
If you already own a Wave Mini and it shows a rising risk reading, treat that as a reason to check the room. Look at the visible surfaces, fix any moisture problem you can see, and bring in a professional for anything serious.
Frequently asked questions
What does the Airthings mold risk indicator mean?
It is the Wave Mini's estimate of whether conditions in the room favor mold, based on temperature and humidity. It is not a mold test result and it does not confirm that mold is present. A high reading is a reason to check the room, and anything serious should be confirmed by a lab sample or a licensed inspector.
Is there an Airthings mold detector?
Airthings sells the Wave Mini, which people often call a mold detector. It is an air monitor that estimates mold risk from temperature and humidity, and it runs about $80. It does not detect mold or spores, so use it to watch conditions and use a photo screen or a professional to check for mold itself.
Does Airthings detect mold in Los Angeles?
No, and the city does not change that. The Airthings Wave Mini does not detect mold or spores anywhere, including in Los Angeles homes. It reads temperature and humidity in the room where it sits and flags conditions that favor mold. For a suspicious spot, screen the visible surface with a photo or bring in a licensed inspector or lab.
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 is an AI-assisted visual screening tool with 266 guided photo prompts across 19 rooms. Quick uses 38 prompts and Standard uses 129. It screens visible surfaces for visual cues and returns a local report that states the camera limitations; processing time varies. The main difference is a sensor that predicts risk from conditions versus a visual screen of submitted photos.
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 useful for monitoring humidity over time. Mold Scanner is for guided AI-assisted screening of visible surfaces across the home. Its local report can show the submitted photos, visible cues, camera limitations, and conservative next steps, but it is not evidence that mold exists. Use the sensor to monitor conditions and the scanner for a first-pass visual 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 can investigate beyond camera-visible surfaces and collect samples when needed. Use a sensor to monitor and a scanner to screen, then bring in a licensed inspector or lab for anything serious or high-stakes.
