YES, providing that you use pure essential oils. After 2–5 days, most of the essential oils successfully volatilise; of course, there are exceptions which smell longer, like patchouli or ylang-ylang... The great advantage of Lady Pinecone is its receptivity to new scents and the ability to “clean itself” from the old ones. Because of that, it is more ecological and safer, plus if you take proper care of it, it’ll last many years.
