Fresh Air machine SG500 | Whole House HEPA Filter Air Ventilator and Energy Recovery Machine

  Technology 1:Electrostatic precipitator The core component of the electrostatic dust remover, electrostatic dust collector, can be taken out at any time. The purification effect can be seen as 6000V high voltage electrostatic, and the current is only 1-3mA, which is smaller than the mobile phone current, safe and reliable, maintenance only needs cleaning and no consumables. It is convenient and economical to filter dust smaller than PM2.5. Technology 2: Electrostatic sterilization Electrostatic tungsten wire releases high voltage static electricity of about 6000 V, killing bacteria, viruses and so on instantly, which can effectively reduce the probability of various air-borne diseases. Technology 3: Filter formaldehyde (optional, need to be purchased separately)  Using pure coconut shell as the base material, after deep processing and three improvements, the pore structure is developed and the adsorption capacity is strong Overview Model Number: SG500 Power (W): 54-140W Vol
