Do you have direct experience with forms of incense that do not activate asthmatic reactions in children with sensetive systems?

I have been reactivating my daily meditation practice. I realize that rituals like lighting incense are completely unnecessary, but it is nice to have a routine. I know that the incense we have around the house makes my five year old’s respiratory system go crazy. I have researched smokeless incense, oils, etc. on-line; but, I don’t know if I can truly rely on any of these products to: (a) have no impact, or even a positive impact, on my daugher’s lungs; and, (b) remain easy to acquire and use as part of a daily meditation practice. I am happy to give the whole search up, but I thought I would tap the collective first.
