Asthma black filled icon
Outlined human lungs with windpipe and short bronchial branches marking asthma airways
About the Asthma black filled icon
Two lungs are drawn side by side with the windpipe rising between them and short bronchial branches scattered across both lobes, marking inflamed airways. It reads instantly as breathing difficulty, respiratory illness and lung health. Use it on clinic websites, hospital department menus, inhaler and medication apps, health insurance forms, and biology or patient-education slides.
The outline keeps a wide, rounded outer contour with even stroke weight, so the small airway marks stay legible when scaled down. It sits naturally beside heart, kidney and stethoscope icons from the same anatomy set. Below 24 px, prefer the filled style.
This is the solid black filled version of the asthma icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
