How to save on expensive cost of up-sizing filters Needlepoint Bipolar Ionization technology produces positive and negative ions that travel with the supply air into the space. In the space, these ions cause particles like dust, dander, pollen, bacteria and virus to attract and stick together (agglomeration). This action significantly increases the effectiveness of existing… Read more »
