Can I add scents, medication or oils to the water? No medication should ever be added directly into the water. If you would like to use a mentholatum scented inhalant, then you can place it in the medicine cup of a warm mist humidifier or vaporizer. We recommend that no scents or oils to the humidifier as we do not or understand the affects they may have on the humidification process. We have created and tested some scent tablets for the water that are available for purchase as well. < Back
