This 2156A filter is a dedicated replacement accessory for the Bissell Zing series bagless canister vacuum cleaners. It precisely fits models 2156, 2156A, 2156E, 1665, 16652, and 1665W (corresponding to the original part number 1613056) and is not compatible with models such as 203-1531. 
 
The filter features a 'pre-filter + HEPA filter' design: the pre-filter captures large particles such as hair and food debris, while the HEPA filter traps 99.7% of fine dust as small as 0.3 microns (including pollen, pet dander, and dust), and also blocks fine dust larger than 0.1 microns from entering the motor, protecting your device and enhancing cleaning efficiency.
 
It supports washable reuse: it is recommended to rinse with water once a month and let it air dry for 24 hours before reinstalling. To maintain optimal performance, it is recommended to replace it every 3-6 months, depending on usage frequency.
 
Installation is simple: open the vacuum’s bottom cover, insert and twist the filter to secure it, then close the cover—no tools required.
 
The package includes 2 HEPA filters, meeting your replacement needs for a period of time and keeping your Bissell Zing vacuum cleaner performing at full cleaning power.
