"220V AC Cooling Fan" PP meltblown filter can effectively filter impurities in the water cycle, including dust, smoke particles; while silver and ceramic balls can efficiently remove bacteria circulating water, the two technologies can achieve dust sterilization double effect, so wash water continuously clean the air circulating. Secondly, in the "220V AC Cooling Fan" air purification, clean house chiller also used PET platinum coating efficient dust filters and efficient sterilization net two silver fiber technology. "220V AC Cooling Fan" PET platinum coating efficiency dust masks network equivalent of several superimposed together, can prevent oil, stain removal, and powerful filtering dust resistant bacteria.
