Saratech Permasorb: Wallpaper That Cleans the Air

Saratech Permasorb 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.” If your requirement is a wall covering that captures pollutants from the very air you breath, the profile you want for these charcoal-like absorbents is small, evenly distributed, and extremely porous–all the better to create the requisite large internal space to permanently capture and store contaminants.
