Buy 3 plants this weekend, get cleaned air in your home or office all year long.

Love is all you need?

If you live in New Delhi—or any polluted city—love is not enough. But these three houseplants are…all you need for a clean, fresh air that provides a measurably healthier environment for your body, and its brain.

Three-minute Video detailing how many plants, how high, per person, with cleaning instructions. Via TED.

With thanks for the tip to GreenUpgrader, one of my favorite green sites:

Seventeen years ago Kamal Meattle found out that the air in his home city of Dehli was killing him.  He had grown allergic to the pollutants in the air and his lung capacity started declined to 70%.  He began researching and found that these three plants can provide a human with all the fresh air they need indoors to be healthy.  The three plants are the Areca Palm, the Mother-in-law’s Tongue , and the Money Plant….

  • The Areca Palm (or Chrysalidocarpus lutescens) is does great air cleansing work during the day.  About 4 shoulder height plants per person should do the trick.
  • The Mother-in-law’s Tongue (or Sansevieria trifasciata) takes over by converting CO2 to O2 at night.  You want about 6 to 8 of these waist high plants per person.
  • The Money Plant (or Epipremnum aureum) does the job of filtering out removing Formaldehyde and other VOC’s (Volatile Organic Compounds).

…According to Meattle if you have sufficient quantities of these plants you could live in an air tight bubble and as long as the plants are living you’d have enough fresh air to live.  Now this isn’t just some half-baked theory he had one morning over coffee, he has been testing this theory out for the last 15 years at the at Paharpur Business Centre, a 20 year old, 50,000 sq ft building by filling it with over 1,200 plants for 300 building occupants.

The Indian Government has rated the building the healthiest buidling in Delhi, and studies have shown that after spending 10 hours in the building your body will be working better than before.

Aside from being a natural and beatiful source of fresh air, this method also helps reduce energy consumption, because you don’t need to filter or bring fresh air in.

Now Meattle, has big plans. …

Bonus: NASA spent time working out the best plants to clean the air in space stations

    Have you ever been to Delhi? The first hit of "air" when exiting the Indira Gandhi Airport is enough to give you a soul-threatening fever and life-time recurring susceptibility to infection. Maybe there's an organic green snuff for the snoz, or an aerosol-free green spray to use on a nicely pressed bandana upon stepping out. 17.3 million folks doing time in Delhi – that's half of all of Canada. A minimum of 50 million pollution eating plants needed.

    According to a NASA study, there are plants that are excellent for cleaning the air of toxic pollutants like benzenes (from computers) and formaldehyde (in carpets and furniture). Dracaena (several types), philodendron, chrysanthemum, English ivy, bamboo palm, gerbera daisy, pothos and spider plants are all excellent air cleaners.
