Logo

The OpenAQ logo is a critical brand asset that represents OpenAQ’s mission to democratize air quality data. To maintain brand consistency and integrity, the logo must be used correctly across all applications. Always use the official, unaltered version of the OpenAQ logo. The logo has been carefully designed and should not be modified, recreated, or altered in any way. Always use the appropriate asset size and maintain the logo aspect ratio to avoid pixelated and/or distorted appearance.
