This Air Quality icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,600 icons, all in the same style and quality.
It's a logo of a rectangle in portrait orientation with curved edges. Coming through the rectangle from left to right are curved line waves. There are three of them and they curve down then up then down.
