Independent. Practical. Made in Québec.
Air quality tools built to turn readings into informed action
VisiblAir designs air quality monitors and connected software for people who want to understand the air in a home, classroom, workplace or multi-room building.
Choose a portable monitor for direct checks or a connected model for remote readings, history and alerts. Our current range measures CO₂ and, depending on the model, particulate matter, volatile organic compounds, temperature and humidity.
Why VisiblAir began
From a classroom ventilation question to a broader view of air quality
During the COVID-19 pandemic, concern about ventilation in Québec classrooms raised a practical question: could a small connected monitor collect CO₂, temperature and humidity readings regularly and make the history available remotely?
That question became co2.click. Early monitors supported continuous measurements instead of isolated spot checks, helping people see patterns over time and evaluate the results of ventilation changes. In 2021, co2.click monitors were part of the documented CovidStop pilot project in Montréal businesses.
As the product range grew beyond CO₂, the name no longer described the full work. In March 2025, co2.click became VisiblAir: the same independent project, with a name broad enough for particulate matter, VOCs and the connected tools around the monitors.

Local work, useful data and accountable support
Built in Québec
Monitors are engineered, assembled and tested in Québec, Canada. Enclosures are 3D printed, products are prepared to order and shipments leave from Canada for destinations worldwide.
Your sensor data
Our published privacy statement says customer sensor data belongs to the customer, is stored on servers in Québec and can be exported in standard formats.
A repair path
Our terms document warranty service and repair options for eligible products after warranty. We assess the appropriate option through the return process.
Direct answers
Questions go to a published customer-service address. The owner normally responds to multi-unit quote requests within two business days to confirm needs or next steps.
Milestones

The concept takes shape
André began experimenting with a small connected monitor that could make indoor air-quality patterns easier to see.
First products and recognition
The ecommerce site and Model A launched on March 15. Model B followed on August 15. The project won an Industry of Things World Award in Berlin on September 27, and Model C arrived on November 28. That year also included the documented CovidStop pilot in Montréal businesses.

Model D launched on February 15, followed by Model E on December 15.
New measurements and formats
Model E-Lite launched on June 15, Model X on August 15, and Model G on December 15.
Model F and a broader conversation
Model F launched on January 15. In June, co2.click presented its approach to CO₂, particulate matter and other air-quality indicators at the Collision conference in Toronto; Model O pre-orders opened in December.
