A New Sensor and Six Busy Months of Improvements

Model O has arrived, our cloud tools have taken a big step forward, and updates across the VisiblAir lineup are making your data easier to understand and act on.

Hi there,

It has been a while since our February newsletter—and we have a lot to share. Over the past six months, we launched new hardware and made dozens of practical improvements to the Cloud Portal, public tools, and sensor firmware.

Here are the highlights.

Meet the New Model O

VisiblAir Model O 2026 air quality monitor

The redesigned Model O is built for complete, always-connected indoor monitoring. It measures CO₂, particulate matter, VOC, NOx, temperature, humidity, and barometric pressure, with Wi-Fi, wired Ethernet, and optional Power over Ethernet.

It also offers a local readings page and local API for integrations such as Home Assistant—while keeping the remote history and alerts you already know in the VisiblAir Cloud Portal.

Explore Model O

A Clearer View, Whether You Manage One Sensor or a Fleet

The Portal has been refreshed from sign-in to sensor settings. The new fleet dashboard groups sensors by status and gives multi-sensor accounts a compact operational overview.

  • Faster investigation: recent readings, a 30-day graph shortcut, and smoother custom history ranges.
  • More comfortable viewing: a user-selectable dark mode and cleaner layouts on phones and desktops.
  • Safer collaboration: self-serve sensor sharing, clearer access levels, and full-day alert muting.

Clear Answers for Every Step

We added quick setup guides for every supported model, directly on each product page. Per-model firmware changelogs and the Portal changelog also make it easy to see what changed.

A Complete Cloud Portal User Manual

This illustrated 12 MB manual covers the complete journey: signing in, adding and managing sensors, live readings, alerts, sharing, maps, graphs, data exports, firmware updates, and troubleshooting.

See Your Readings in a Bigger Context

Our rebuilt Public Map now lets you explore an animated wildfire-smoke forecast beside public sensor readings. Step through the forecast timeline, inspect local and UTC times, and share a link to the exact view you are seeing.

The smoke layer is a modeled forecast, not an observation of smoke or fire spread.

Individual public sensor pages were modernized too, with a cleaner mobile layout and more reliable graph timing and pressure scaling.

Firmware Updates Across the Lineup

Recent releases improved Wi-Fi and LTE recovery, exposed clearer signal, carrier, uptime, and sensor-health details, and made LTE firmware downloads much faster.

Model G received display and clock-sync fixes, while Model X now reports Wi-Fi signal strength.

We are also working to bring stronger offline-data protection to every compatible cloud-connected sensor, so locally saved readings remain safe during Portal outages, upload progress is visible, and backlogs clear more quickly after service returns.

What Story Is Hiding in Your Sensor Data?

We are looking for five curious VisiblAir owners to test something new and share candid feedback. You must own a VisiblAir sensor; one that usually stays in the same place is ideal.

I’m Interested

Thank you for using VisiblAir, sharing your feedback, and supporting an independent Canadian company. Every improvement above grew from real-world use and conversations with sensor owners like you.

Engineered to help you breathe better.

Hello,

As the holiday season approaches and 2025 comes to a close, we wanted to take a moment to reach out with honesty, gratitude, and hope.

Let's be honest: 2025 was a challenging year.

Like many small, independent hardware companies, VisiblAir faced a number of obstacles:

  • 🇺🇸 U.S. tariffs, increasing costs and uncertainty
  • 🌍 Geopolitical instability, impacting sourcing and logistics
  • 🚚 DHL service disruptions and Canada Post strikes, complicating deliveries
  • ⏳ Longer component lead times, forcing ongoing production adjustments

To be transparent, although still cash positive, 2025 was not our strongest year financially.

But it was a year of resilience.

Despite the headwinds, VisiblAir kept moving forward — designing, testing, improving, supporting customers, and staying true to our core mission.

That mission has never changed:
Make the invisible visible.
Provide high-quality air-quality monitors that are:

  • Simple to use
  • Reliable and durable
  • Transparent in their data
  • And that allow you to put real numbers on the air you breathe

🙏 Thank you — truly

Above all, thank you.
Thank you for choosing VisiblAir, for trusting us, and for supporting a mission-driven Canadian company focused on healthier indoor air.

🎁 A small end-of-year thank-you

As a token of our appreciation, we're offering you 10% off your next order:

If we can measure it clearly, we can improve it.

We wish you happy holidays, a restful end to the year, and a healthy, bright start to 2026 🎄🌬️

Warm regards,
Andre Courchesne
Founder & Inventor, VisiblAir

Hello from VisiblAir! 👋

We've got some news, tips, and a little invitation to share — here's what's been happening in the world of VisiblAir! 🌿📦

📦 Canada Post Strike – More Shipping Options Available

Canada Post is currently in strike action, which has been causing delays and uncertainty with regular postal shipments. To make sure you still get your VisiblAir products without interruption, we've enabled additional shipping methods on our store. This means faster, more reliable options are now available at checkout so you can continue to receive your sensors and accessories with peace of mind.

🇺🇸 U.S. Tariffs – An Update for Our American Customers

As of August 29, 2025, the United States has suspended its duty-free de minimis threshold of US$800 for all imports. Every postal shipment into the U.S. now requires prepaid duties before crossing the border.

So far, we've been hit twice with the new 35% tariff on shipments to the U.S. These unexpected costs completely erased our margin on those orders. Interestingly, not all shipments have been affected — the rules seem inconsistently applied, and we are actively monitoring the situation.

If tariffs continue to be charged, we may need to adjust U.S. pricing to reflect this. For now, we'll keep absorbing the costs where possible while we seek clarity and solutions.

🌬️ CO₂ Calibration Reminder – Before the Cold Months

For those living in colder regions, now is the perfect time to check your CO₂ sensor calibration before winter:

  1. Place your sensor outside on a mild day (temperature above 10 °C).
  2. Keep it sheltered from wind, at least 6 ft from windows, doors, or vehicles.
  3. Let it acclimate 5–10 minutes.

If your reading is between 400–450 ppm, you're good. If not, we recommend recalibration to ensure accurate indoor air quality monitoring during the months you'll be relying on it most.

🏗️ Meet VisiblAir at Expo Contech Bâtiment – Quebec City, Oct. 23

We're excited to announce that VisiblAir will be at Expo Contech Bâtiment in Quebec City on October 23, 2025 🎉

🛠️ Ensure Your CO₂ Sensor Is Ready for the Cold Season ❄️

As the temperatures begin to drop and the cold season approaches, many of us will be spending more time indoors with windows closed tight against the chill. This makes it more important than ever to ensure that your CO₂ sensor is accurately monitoring your indoor air quality. 🏠
With increased indoor activity and less natural ventilation, CO₂ levels can rise quickly, affecting comfort and health. An accurately calibrated CO₂ sensor helps you stay informed and take action when necessary. 🌬️
You can easily verify your CO₂ sensor's accuracy with a quick outdoor test:
  • 🌤️ Choose the Right Day: Select a day when the outdoor temperature is above 10°C (50°F). Mild temperatures ensure the sensor operates optimally during the test.
  • 📍 Ideal Location Matters: Place your sensor outside in an open area away from direct CO₂ sources like windows, vehicles, or people. Avoid areas with heavy traffic or crowds.
  • 📌 Special Note for Model F Users: The Model F sensor is sensitive to wind. To shield it, place the sensor in an open container, which allows air circulation without wind interference.
  • ⏳ Allow the Sensor to Stabilize: Let the sensor run for about 10 minutes to acclimate to the outdoor environment.
  • 📈 Check the Reading:
    • ✅ Between 400 and 450 ppm: Your sensor is properly calibrated.
    • ⚠️ Outside This Range: It's time to recalibrate your sensor.
