Purchased in 2009. It is no longer sold. The color is orange. It is new and unused, and has not been opened. Please refrain from purchasing if you are concerned about home storage. Air Disinfection with High-Density "Plasmacluster" Technology The "Plasmacluster Ion Generator" emits ions at a concentration 3.5 times higher than those found in air purifiers! It releases "+" and "-" ions, the same as those found in nature, "Plasmacluster Ions." When these ions attach to the surface of airborne bacteria, they transform into highly oxidizing "OH radicals," which instantly remove hydrogen (H) from the proteins on the bacteria's surface, breaking down the proteins. This quickly disinfects and decomposes bacteria and viruses in the air. "Spot Deodorization" for Unpleasant Sweat Odors on Clothes By concentrating high-density "Plasmacluster" wind from below clothes hung on hangers, the "Spot Deodorization" function (※1) gently deodorizes clothes overnight. It also decomposes airborne bacteria and deodorizes odors that have permeated curtains and sofas. Compact Design for Spot Use With a compact design of approximately 9cm in width and 15cm in height, and a 3m long AC adapter, it can be easily carried and installed in narrow spaces such as walk-in closets and kitchens. It also comes with a cord holder for the AC adapter, making storage convenient. Quiet Operation and Economical for Long-Term Use The operating noise is 29dB (※2), making it a quiet design for comfort. Moreover, even when used all day (24 hours), the electricity cost for one month is only about 22 yen (※2), so you can use it every day with peace of mind. High-Density Maintenance Design To constantly and stably emit high-density Plasmacluster ions, a Plasmacluster unit replacement system is adopted. The replacement time is about 2 years (when used continuously for 24 hours), and a lamp will light up to notify you when it's time. ※1 Odors in areas not directly exposed to the airflow will not be removed. ※2 Both operating noise and electricity costs are for low-speed operation. Electricity costs are calculated at a power rate of 22 yen/kWh. Sharp SHARP Plasmacluster Ion Generator High-Density Plasmacluster 25000 (Portable Type) Blue Series IG-B20-A
