This document compares the specifications of three air purifiers labeled SP-1, SP-2, and SP-3. All three purifiers use photoplasma/photochemistry for purification and generate negative ions through photoionization. They can treat different maximum area sizes and have slightly varying UV and electrical outputs and weights. The ozone accumulation for all will not exceed 0.04ppm.
