Features: Precision dust removal; Anti-mildew and deacidification; Sterilization and disinfection; Removal of harmful gases. 1. Multi-functional filter The air purification unit consists of a metal pre-filter (removes larger particles), an electrostatic adsorption device (professionally removes PM2.5 particles), a medium or sub-high efficiency filter, an activated carbon gas filter, an activated alumina filter, a photohydrogen ion purification device, and a low-noise fan. 2. Product intelligence Equipped with an air pollutant sensor, it dynamically displays the potential air pollution level at all times, and the machine automatically adjusts the air volume based on the pollution level. The unique control program not only displays the machine's normal operation status and fault information but also indicates the replacement time for the activated carbon filter, providing timely reminders to users. 3. Easy maintenance With a unique structural design, users can easily open the air intake panel to remove the pre-filter, electrostatic adsorption device, and activated carbon filter without using any tools. The pre-filter and electrostatic adsorption device can be reused after cleaning. 4. Installation method: Floor-standing and mobile Purification targets: Inhalable particles/microorganisms/toxic gases and odors: indoor gases, such as benzene, formaldehyde, ammonia, organic acids, and organic compounds released from furniture, storage rooms, carpets, chemical cleaning agents, photocopiers, insulation materials, pesticides, hair sprays, etc.
