SpringAir Purifiers: Modern buildings are constructed so tightly that odors and pollutants are trapped inside Nature's own cleansing process, which uses both activated oxygen and negative ions are left outside. Dust, pollen, molds, mildew, bacteria and viruses can fill the air in our living spaces. These can cause odors, irritation and allergic response. You and your family also breathe fumes from paints, cleansers, carpets, pressed board, fabrics and other chemicals in daily. Purifiers can generate the negative ions that nature uses to clear the air of dust and other particles. It also produces activated oxygen to remove odors without the use of fragrances. It helps to break down mold, mildew and other pollutants at their source. Our state-of-the-art purifier generates both negative ions and activated oxygen for your home or office.
