Re: TED 2009: How to Grow Your Own Fresh Air
#2With only three varieties of plants, we can grow our own fresh air indoors, to keep us healthy.
After studying the effects these plants had on air quality for the past 15 years in a building in New Delhi, India it was found that there was a 42% probability of increasing blood oxygen by 1% simply by being in the building for one hour. Compared to other buildings in the city, eye irritation was reduced by 52%, respiratory symptoms down by 34%, headaches by 24%, lung impairment by 12%, and asthma by 9%.
They were also able to reduce the fresh air supplied to the building and still meet industry standards for healthy indoor air, netting a reduction of energy costs by greater than 15%. With buildings consuming 40% of the world’s energy, this is a big deal.

RiderOfGiraffes, thank you. Couldn't find a "search box", hence the somewhat duplicate entry. The page posted today should be more useful to readers, as it has many more actionable details. The talk was given by my father.

The data shows that they work well together.
Areca Palm is good for the day, while Mother-in-law’s Tongue works during the night. Money Plant helps remove toxins like Formaldehyde (from carpets and furniture) from indoor air.

#9This is great. These plant are also very common and therefore easy to get and don't cost much. I think I've seen the Areca Palm at Ikea.
Do you have any pictures of how it looks inside the building?

You're welcome. As others have said, there are search facilities, but they're not easy to find. I agree that this link is better than the other. Sometimes the "duplicate" is of greater value.
It would be really useful to be able to cross-reference items more easily, and then to merge discussions and comments, but I suspect that won't happen.
Anyway, interesting talk, interesting idea. Thanks to you and your father.
