New research finds that certain houseplants are best for removing specific harmful compounds. It’s not new news that houseplants are beautiful little workhorses when it comes to human health. Among their many benefits is one decidedly impressive one – they remove toxins from the air. And this isn’t just woowoo mumbo-jumbo. NASA, given their interest in improving air-quality in sealed environments, has researched this extensively and concluded: “Both plant leaves and roots are utilized in removing trace levels of toxic vapors from inside tightly sealed buildings. Low levels of chemicals such as carbon monoxide and formaldehyde can be removed from indoor environments by plant leaves alone.”
