Interesting. You need 6-8 healthy, waist high plants in your house per person to keep the air clean and healthy? I suppose those plants should all be currently alive. I’m going to have to get to work.
Also, you need to take your plants outside for a while every few months. I’m not sure what that does. Is this to purify the plants so they can keep purifying the indoor air?
Anyway, I found this video via Life Hacker. They have links recommending other types of plants for the same purpose.
Anybody priced a ficus tree lately. It sounds like I need a ficus forest in my house.
