Pre-Order Deal: Save 5% on EcoQube Flex until December 15, 2025, with code E-PREORDER5

Ecosense offers a full lineup of Smart Home Radon Monitors—EcoBlu, EcoQube, RadonEye, and now the newest addition: EcoQube Flex. EcoQube remains the bestselling model, trusted for its fast, accurate radon detection with Wi-Fi connectivity and remote monitoring. In November, Ecosense introduced EcoQube Flex, a portable, battery-powered version designed for room-by-room radon mapping and convenient testing anywhere.

Both models use Ecosense’s patented ion-chamber sensor with industry-leading 15× sensitivity and deliver results within minutes. For many households, choosing between them comes down to power, portability, connectivity, and how you prefer to monitor radon day-to-day.

1. Portability: Power + Connectivity

Radon levels can vary significantly between rooms and floors, which is why many homeowners relocate their device from time to time. This is where portability and convenience become especially important.

EcoQube

• Plug-in powered, which limits mobility since it must remain close to a power outlet
  

• Continuous Wi-Fi is required for remote access and cloud syncing
  

• Relocating EcoQube involves performing a standard device reset before placing it in a new room.
  Pro Tip: Resetting clears the device’s live readings, so previous data must be saved manually (screenshot or note) if you want to compare radon levels between rooms. This reset takes only a few seconds but is important to ensure accurate results in the new location.
  
  

EcoQube Flex (New!)

• Battery-powered for up to 7 years and does not rely on Wi-Fi, making it fully portable
  

• Ideal for testing anywhere in the home, including areas without electricity or internet (basements, attics, garages, crawl spaces, cabins, new builds)
  

• Relocating EcoQube Flex also involves a device reset; however, previous data stays saved in the app, allowing automatic room-by-room comparison. Each location is stored as a labelled room in the app, making trends easy to compare at a glance.
  
  

2. Display & On-Device Results

Choosing between EcoQube and EcoQube Flex ultimately comes down to how much information you want to see day-to-day. While the on-device visibility is different, most homeowners use the mobile app for more detailed results and deeper insights:

EcoQube

• 3-color LED indicator shows your radon range at a glance:
   Good (Green) / Moderate (Orange) / High (Red)
  

• No numeric display — ideal for those who prefer a minimalist, low-profile look
  
  

EcoQube Flex

• Always-on numeric display provides great on-device visibility:
  

• Current or average radon level
  

• Highest reading (past hour or selected test duration)
  

• Lowest reading (past hour or selected test duration)

3. Remote Access

We often place radon detectors in the basement or other areas we don’t visit every day, so having remote radon monitoring makes life much easier.

EcoQube

• Wi-Fi connected (requires a 2.4 GHz network)
  

• Automatic syncing: Your data updates whenever you open the app

• Remote access benefits:
  

  • Check radon levels from anywhere, even when you’re travelling

  • Share device access with family members or radon professionals
    

EcoQube Flex

• Bluetooth-based app experience
  

• Syncing: You need to be near the device (within about 10 feet) for the app to update data
  
  

4. Data Insights, Timestamps & Trends

Both EcoQube and EcoQube Flex deliver an insightful app experience designed to help you fully understand your home’s radon levels. The app provides visual charts, interactive graphs, seasonal trends, and timestamped data logs, allowing you to see exactly when radon levels rise or fall throughout the day.

EcoQube Exclusive: 72-Hour DIY Radon Test (U.S. Only)

EcoQube includes a unique capability that no other Ecosense home radon monitor offers — a built-in feature called My Radon Analysis, which provides:

• A detailed, structured 72-hour test report
  

• EPA-aligned recommendations
  

• In-depth explanations of your radon levels and what they mean

This feature is especially useful for validating mitigation effectiveness or confirming whether further action is needed.

5. Design & Home Integration

If you place a radon monitor in a highly occupied area, like your living room, you want it to blend naturally with your interior. Both devices are thoughtfully designed, but they offer different visual styles and levels of interaction.

EcoQube

• Compact, palm-sized cube design in black
  

• Sits discreetly in any space without drawing attention
  

• Minimalist look with no buttons
  
  

EcoQube Flex

• Compact, display-forward design in white
