How to Build a 'Living' Air Purifier Using Vertical Moss

Why buy a plastic machine when you can build a biological one? This weekend project walks you through creating a "Living Wall" that naturally filters dust and VOCs from your home office. Step 1: Construct a cedar frame (24x36 inches). Cedar is naturally rot-resistant, which is essential for a moist environment. Step 2: Install a moisture-wicking felt backing. This will act as the "soil" for your moss. Step 3: Source live sheet moss. Unlike dried moss, live moss actively processes the air. Step 4: Setup a gravity-fed drip system. A small reservoir at the top will slowly hydrate the felt over a week. In just three hours, you'll have a self-sustaining air filter that removes up to 90% of household pollutants while acting as a stunning piece of wall art. Maintenance is as simple as refilling the water tank once a month.
