Carpet Freshener/Deoderizor

I would love to have a carpet deoderizer from seventh generation. I have carpet all through the upstairs of my house. I don't like using glad or any of those other brands (and I have used them all). Main reason being is I have a two year old, and those other brands are too harsh with the smell and they makes us both itch, and I'm am pretty sure they aren't the safest thing to use. I do spot clean which seems to help a bit, but I would love something that I can use to freshen up the room, even a deoderizer spray like fabreeze..which i cant use either.
