Shield cleans the air by removing 99.8% of harmful substances such as viruses, bacteria, and ultra f ine dust in the air through the patented 2WAY double purification technology (plasma anions and UV-C double sterilization method). It is the only system in Korea that realizes effective air purification by combining the double sterilization technologies of plasma and UV-C. Anion + positive ion bio-plasma technology generates a total of more than 400,000,000 anions and cations. 1. It is produced in Korea, and we have completed KC supplier compliance, physical safety, chemical safety, radioactivity test, electrical safety, and hazardous substance limitation test. We have even completed electromagnetic compatibility test that you are worried about. 2. With a low-noise DC fan, it is comfortable and not intrusive with an ultra-low sound (20-25dB) of leaf hitting at 1,700 RPM. 3. SHIELD offers fan air volume control (steps 1 through 4) that set it apart from other products. It delivers negative ions and positive ions quickly, quickly removing harmful viruses and odors. Beyond simple ventilation, it helps to effectively control unpleasant elements in the air and keep the indoor environment pleasant. This adjustable fan speed is key to the best air quality. 4. There is no cost to maintain consumables with simple cleaning once a week without changing the filter. Unlike regular air purifiers, it protects against harmful substances and microorganisms without changing the filter. 5. It is a wired/wireless combination, so you can carry it after charging it and use it regardless of location.
