The demand for houseplants is currently growing thanks to social networking sites and home magazines. They are nice to look at and transform the place into an urban jungle no matter whether you have a big city loft or a shared room. But not only that – they also have superpowers. Plants ensure that the air you’re breathing is fresh. They filter out pollutants that are emitted by furniture, varnish, paint, plastics, and chemical cleaning agents. And in summer, when you open your windows and patio doors, your green guardian angels protect you from pollen and car exhaust fumes. Just one plant per 100 square feet works wonders. Most of them expect next to nothing in return. Don’t worry if you don’t have a green thumb though, because air purifying plants are often uncomplicated.
