Might not that useful in NZ due to low air pollution. But if you have smoker at home, or running 3D printers in room, or like to have a gap of window open in winter while your house is surrounded by friendly neighbors who burn weird stuff in their fireplace, or like me has an office next to a car tuning garage always smokes.

The filter is same as their old model HY4866's filter, size is 285x255x30mm. The unit uses 2 filters(front and back) each time, there are 3rd party filters available, did a search it is about NZ$70 to get 5 packs of the filter(2 filters in each pack) including sea freight and GST from Taobao.com.
