Blücher Technologies has created Saratech Permasorb -- a wallpaper that functions as an air filter:

The product is a “breathable, glass fiber/polyester nonwoven paper-like covering” containing absorbents that naturally capture toxins like PCB, PCP, pesticides, and radon—each of which were a de rigueur byproduct of construction during the 60s and 70s. The key to Permasorb’s functionality is a profusion of tiny, perfectly round black spheroids that resemble the most uniform collection of poppy seeds you’ve ever seen. As Blücher says, the size and shape of these are crucial: “particle size distribution, mechanical properties, and surface chemistry can be customized according to the requirements.”
