I can say the Sterra USA is very helpful keeping the dust down in our home. We have a Shih Shu that stays inside all the time. She started sneezing & showing signs of allergies. Your machine is helpful & im able to keep my house cleaner. I also purchased a Sterra USA for my daughter to help with her dog dander. i highly recommend thos brand.
