25W air purifier specifically designed for sterilization and deodorization, operating on DC12V. Power-on (see photo 3) and operation confirmed. Purchased in May 2020 and used intermittently until recently. The filter has been cleaned as much as possible, and it can be used as is, but the HEPA filter has deteriorated over time, so replacement is recommended (available on Amazon for around 3,000 yen for two). There are also small scratches on the main unit due to use (see photo 8). ■ Product Description The Nitride Semiconductor "LED PURE" AM1 is an air purifier that powerfully sterilizes and deodorizes viruses, bacteria, pollen, PM2.5, etc. in the air with a high-performance UV-LED and photocatalytic filter. *Nitride Semiconductor Co., Ltd. is a company that manufactures and sells UV-LEDs, headquartered in Naruto City, Tokushima Prefecture. ■ Specifications NITRIDE AM1B Size: 167 x 128 x 260mm (width x depth x height) Weight: 1.5kg Applicable area: 40㎡ Operating noise: 50.0dB (airflow: medium) Rated voltage: DC12V Power consumption: 25W ■ Features ・High-performance UV-LED Equipped with a 275nm deep ultraviolet LED, it sterilizes and deodorizes viruses, bacteria, pollen, PM2.5, etc. by 99.9% or more. ・Removes not only pollen but also ultrafine particles Pollen, which is larger than PM2.5, is removed by the "pre-filter," and even ultrafine particles of PM0.3, which are finer than PM2.5, are removed by 99.9% by the "HEPA filter." ・Photocatalytic filter: The photocatalytic filter is activated by the UV-LED light and decomposes and removes attached viruses, bacteria, and odors.
