This diffuser is an absolute favorite of mine! In fact, I have three of them set up in different rooms of my house. Using the immunity blend in all of them gives me the confidence that germs are being effectively dealt with, and as a result, my household is staying healthy. The fragrance it disperses is delightful, and the ease of use makes it even better. Without hesitation, I wholeheartedly recommend this product – it has earned my highest praise!
