Forespar Tea Tree Essential Oil Refill Pouch 44oz (2-Pack) - 100% Pure Natural Aromatherapy Oil for Diffusers, Massage & Skin Care

We have used this in our boat for the last few years. We come to our boat about every 3-4 weeks . The boat is kept in Florida where it is warm in the winter and very hot in the summers ( we do not use the air conditioner unless we are on the boat). The boat has never had any mold issues anywhere. We have multiple canisters through-out the boat and in the lazarettes. The product is as good as the Kanberra, which is more expensive. Highly recommend this product.
