TED – Growing AIR – recycle indoor air 100% with just 3 plants. : CTN GREE… – StumbleUpon. Just a word of warning to pet owners who read this article. I checked at the ASPCA and two of the plants are poisonous to dogs and cats. I said this:

Mother-in-law’s tongue and Money Plant is also poisonous to dogs. You can read more or find out what plants are poisonous here. Areca Palm is not poisonous. You should update this article. Many people have pets and this could seriously hurt them.
