Breathing clean air is essential for human health, making air filters indispensable in homes, hospitals, workplaces and industrial settings. However, despite decades of advances in filter materials and design, a major challenge remains. Capturing airborne particles is only half the battle; keeping them securely trapped is equally important.

Conventional air filters rely on weak adhesive forces, allowing some captured particles to detach and re-enter the air. This reduces filtration efficiency, shortens filter lifespan and highlights the need for smarter, more durable air filtration technologies.
