10 Best Mold Detectors 2025 in the United States

The GOT MOLD? Test Kit is designed for professional-quality mold detection in a home setting, offering a straightforward and user-friendly experience. It uses the BioVac Air Sampler, which ensures accurate detection of mold spores and takes only 5 minutes per room, making the detection method both efficient and practical. The kit includes everything needed for testing, including air sampling cassettes and a prepaid return mailer, which simplifies the process immensely.

Results are comprehensive and detailed, with a PDF report that includes types and quantities of molds, along with color-coded interpretations and recommendations for next steps if mold is detected, ensuring high accuracy and useful data logging and reporting. The quick response time (within a week) for results is a significant advantage, and the kit's portability is enhanced by its compact design and lightweight (1.8 pounds).

The reusable nature of the BioVac Air Sampler adds value for long-term use, although needing cassette refills for additional tests might be a minor inconvenience. This product is particularly beneficial for homeowners, tenants, and property managers who need to promptly address potential mold issues. Its ease of use and detailed reporting make it an excellent choice for those who prioritize health and safety in their living spaces.

The Evviva Sciences Mold Test Kit offers a practical way for homeowners or office users to check for mold in air, on surfaces, and in HVAC systems using 10 separate tests. The detection method relies on agar petri dishes and cotton swabs, which lets you collect samples easily without special tools. Sensitivity is decent, as it can pick up common household molds, but it won’t identify mold types without sending samples to a lab for an extra fee. This optional lab analysis improves accuracy by providing detailed mold identification, which is useful if you want to understand the specific risks. The kit is straightforward to use, accompanied by a downloadable guide with pictures and information, helping even beginners feel confident testing various spots around their home. Results appear within 2-4 days, which is fairly quick for this type of test. It’s lightweight and portable, so you can test multiple locations conveniently.

The kit lacks built-in digital data logging or reporting features; you’ll need to track results manually or rely on the lab’s report if you pay for the analysis. This kit is a solid choice for basic mold detection and awareness, particularly for those comfortable with DIY sample handling and who don’t mind paying extra for detailed mold identification. For quick, simple checks across your home and a helpful guide to understand mold risks, this kit effectively meets those needs.

The Airthings 4200 House Kit is a comprehensive indoor air quality monitoring system that offers multi-room coverage with devices like the Airthings Wave, Wave Mini, and the Hub. While primarily known for radon detection, it also assists in assessing mold risk through humidity and temperature sensors. The system's detection method includes monitoring these environmental factors, which are indirect indicators of mold presence, rather than direct mold detection. This can be a strength for users looking to prevent mold formation rather than identifying existing mold.

The sensitivity of the sensors is robust, capturing small changes in air quality effectively. It boasts ease of use with its wireless setup and smart home compatibility, allowing users to access real-time data remotely via the Hub and receive alerts through IFTTT integration, which enhances its practicality in managing air quality devices like humidifiers and air purifiers.

In terms of accuracy, the devices provide reliable readings that can help create a healthier indoor environment, though direct mold detection might require dedicated mold-specific devices. The response time for environmental changes is reasonably quick, offering timely data updates. Portability is decent; the devices are lightweight and easy to place around the home. Finally, the data logging and reporting feature is strong, offering continuous tracking and historical data access via the Hub. Users looking for a detailed, preventative approach to indoor air quality and mold risk would benefit most from this product, though those needing direct mold detection might seek more specialized tools.
