The water-based air revitalizers are great at cleansing the air in the house of dust. Other bigger particulates, but they’re not created to take care of a few of the smallest particles. If cleaning the air is the main concern, then a conventional air purifier with the HEPA air filter is a great starting point for you. Keep in mind that you can put your personal air purifier in the car to purify the air and keep the air smelling good and fresh.
