Passive air purifier passive purification class (class purifying filter) The main principle is: the fan draws air into the machine, intelligent WIFI purifiers, through the built-in mesh filter air, can play a major filter dust, odors, toxic gases and kill germs. Filter divided: dust filter, to formaldehyde filter, deodorizing filter, HEPA filters. Which is the relatively high cost HEPA filter, WIFI purifier OEM, it can play a role in the decomposition of toxic gases and sterilization, especially suppress secondary pollution. These products are characterized by functionality and quality of the filter fan decided to purify the effect place and the interior layout, the machine is completely purifying effect, indoor purification effect is not balanced, it is difficult to complete, filter replacement cost is higher. Direct evaporative humidifier direct evaporative humidifier is clean humidifier. Direct evaporative humidifier works by evaporation molecular sieve technology, Guangzhou WIFI purifier to remove calcium and magnesium ions can completely solve the "white powder" problem. Water curtain washing through the air humidification while the clean air, and then by pneumatic means moist air to clean the room, thereby increasing humidity. Direct evaporative humidifier has the advantage of not water quality limits. Small size, big wet strength, low power consumption, with APP control purifiers, control performance, the fog particles small and uniform.
