I had this idea perhaps in 2002 I believe after reading an article in which these three certain type of plants would help clean and generate fresh air in our homes. Even though I couldn’t find the original article I found the ones listed below. When I find the photo that I had downloaded from the article I will post here also. In the mean time, check out these articles. This is by far a very good idea as the levels of carbon dioxide in the air is increasing super fast and this would help both children and our elders breathe better. Just a suggestion.
