Houseplants that Improve Indoor Air Quality
In the 1980s, NASA discovered that houseplants could remove volative organic chemicals (VOCs) from sealed chambers designed to achieve maximum air and energy insulation. NASA tested the ability of plants to remove VOCs from the air and therefore eliminate the ‘sick building syndrome’ symptoms experienced by those entering the sealed biohome; see a related study here on the effects of indoor plants on airborne microbial levels and humidity in energy-efficient homes [pdf]. The studies were a success: 12 common houseplants removed formaldehyde, benzene and trichloroethylene, among other airborne toxins, and proved that plants are integral components to maintaining healthy air inside sealed buildings (interior plantscapers and houseplant growers everywhere rejoiced.).
