402SF ) than our previous SmokeStop™ filter. ft.
Since the honeycomb design does not require a thick binding agent throughout, all the absorption pores are open for added filtration capacity. per min. This means the filter delivers a higher airflow (in cu. One complete filter change: One standard HEPASilent™ filter of polypropylene (equal particle efficiency) with more activated carbon for better smoke and gas removal. Its honeycomb-type structure improves airflow and has hundreds of odor absorbing carbon pellets. The higher activation level of the carbon pellets increases efficiency of the filter.
The enhanced SmokeStop™ filter is a new progressive carbon filter.
Like all of our filters, the new carbon filter has a progressive structure with three layers: a chipboard frame and outer layer, a pleat element, and a carbon element.
Compatible with all Blueair 400 Series Air Purifiers (any model number that starts with 4).
The filter uses a high content of granular carbon for increased efficiency, and its new carbon blend is designed to capture more compounds and gases to lower the pressure point.
