A healthy home environment is vital to a person’s well-being and houseplants contribute to it more than you might think. Their main benefit is air-filtering, so it sounds only reasonable that NASA did a Clean Air Study, that found which plants are effective at removing benzene, formaldehyde, trichloroethylene, xylene, and ammonia from the air – chemicals that have been linked to negative health effects like headaches, dizziness, eye irritation, and others.
Dr. B. C. Wolverton led the study about 27 years ago and according to it’s results, The Florist’s Mum and Peace Lily are the best choices for the job. NASA also recommended to have at least one plant per 100 square feet (10 square metre) and although this research is quite old, it is still regarded by many as the most comprehensive and accurate to date.
