San Jose, California - December 15, 2025 - Ecosense, a worldwide leader in cutting-edge radon detection technology, today announced the launch of EcoQube Flex™, the first truly portable continuous radon monitor designed to help homeowners understand and manage their radon risk more effectively than ever before.

The arrival of EcoQube Flex™ introduces a new class of mobile, intelligent radon monitoring, laying the foundation for the next wave of smart home health solutions in 2026 and beyond.

Engineered with Ecosense’s patented ion chamber architecture, recognized for 15× greater sensitivity than industry requirements, EcoQube Flex™ delivers highly accurate, real-time radon insights within minutes of activation. Its enhanced detection engine improves particle sensitivity, reduces noise, and increases long-term measurement stability, positioning EcoQube Flex™ among the most advanced consumer radon monitors available today.

EcoQube Flex™ redefines at-home radon tracking by delivering true portability without sacrificing accuracy or losing data. Homeowners can move the device throughout the home while preserving precise, time-stamped measurement history for each location. What once required professional-grade equipment is now available in a compact, battery-powered device designed for everyday use.

Beyond standard periodic averages (24-hour, 72-hour, week, month, 1-year), EcoQube Flex™ uniquely displays radon peaks and dips directly on the device, revealing the highest and lowest levels within each period. This immediate, on-display visibility provides a clearer understanding of daily and seasonal radon fluctuations, without requiring the app, helping homeowners see how factors such as ventilation, HVAC cycles, and weather patterns influence radon behavior indoors.

The Ecosense App is purpose-built for simplified radon assessment, allowing users to save, label, and compare results room by room, or manage multiple EcoQube Flex™ devices simultaneously. This structured approach transforms raw data into actionable insight, making it easier to identify high-risk areas and make informed mitigation decisions.

2026 Will Bring an Expanded Product Line of Disruptive Radon Technology

Ecosense is leveraging EcoQube Flex™ to expand its award-winning product line into 2026, with a focus on introducing advanced, user-centric features that redefine how homeowners understand and manage indoor air quality. Reflecting its technological impact, EcoQube Flex™ has been nominated for the 2026 Edison Awards, recognizing its innovative approach to portable, continuous radon monitoring.

“EcoQube Flex™ represents a major shift in home health technology,” said Insoo Park, CEO of Ecosense. “For the first time, families can move a radon monitor throughout the home without sacrificing accuracy or losing data. EcoQube Flex isn’t just a product—it’s a platform designed to drive the next generation of DIY-friendly, intelligent home environmental monitoring.”

Redefining Homeowner Control Over Radon Exposure

Traditional radon monitoring has often forced homeowners to choose between outdated mail-in kits or professional instruments costing thousands of dollars. EcoQube Flex™ closes this gap by offering:

• Lab-level accuracy validated by leading U.S. radon laboratories

• True portability with continuous data retention

• On-device visibility into radon peaks, dips, and trends

• App-based room-by-room analysis and multi-device management

• Battery-powered operation for flexible placement

“With radon contributing to an estimated 21,000 lung cancer deaths annually in the U.S., accessible and reliable monitoring is essential,” Park added. “EcoQube Flex™ empowers families with real-time insight and actionable data, helping them make informed decisions to reduce long-term exposure.”
