WASHINGTON – Thirty years ago, a NASA study found that certain houseplants can help clean the air inside space stations, and since that time, studies have confirmed that the same houseplants may be able to do that for a home or office too.

Beyond air quality, other studies have linked certain houseplants to an increase in productivity, calmness, creativity and even a better night’s sleep.

NASA recommends placing up to 18 plants in an 1,800-square-foot house to help purify the air. The best plants to use? Studies highlight these:

• Philodendron
• Aloe
• Snake plant
• Peace lily
• English Ivy
• Spider plant
• Gerbera Daisy
• Dragon tree
• Bamboo
