Custom background colour
Free download of an isometric 3D CO2 indicator icon, ideal for air quality apps, environmental dashboards, and monitoring visuals.
A clean isometric 3D CO2 indicator icon designed for air quality dashboards, environmental monitoring tools, smart home apps, and climate-related visuals. It works well in interfaces about carbon dioxide levels, indoor safety, and sensor data. Free to download and easy to use in digital projects.
The CO2 Indicator Free 3D Icon is an isometric 3D render rather than a flat glyph: soft shadow, gentle highlight, and enough form to survive being scaled down. It arrives as a transparent PNG, so there is nothing to cut out.
You will find it most at home in air quality dashboards, environmental monitoring tools, smart home apps, climate-related visuals and air quality apps.
Sizes on offer are 1024, 512 and 256 pixels, free for personal and commercial projects with a credit to Thridy. Download it free, or request a custom variation if your project needs a different angle, colour or companion icon.
Free for personal and commercial projects. On the free plan, credit Thridy wherever the icon appears: a website footer, video credits, an app's about screen, or a README.
