IQAir 150 air purifier in great condition. Filters have plenty of life left. I will also include the remote control and optional IQAir pre-filter I purchased for this unit which is attached underneath and helps catch more dust and prolong filter life. IQAir is widely regarded as the highest quality air filtration system. This model sells for about RMB 10000 to 12000, new. Selling for RMB 4800. Price is firm.
