I have a lot of pets and sometimes I just like not to smell them so I figured an air diffuser would be a great solution on top of shampooing carpets and other things but I found this is a great add on to my home as I can add whatever fragrance to the air that I want depending on my mood of that day and I don’t have to touch it for 10 hours. It’s very quiet makes little noise and it’s easy to operate and clean.
