Most homes and workplaces have several sources of potential indoor air pollutants. From your pressed-wood bookcase to your office's copy machine, common items release unhealthy gasses that can accumulate and lead to health issues. Use the natural air-cleaning power of plants to purify the air you breathe while greening and beautifying your space.
