Tornado Pre-Filter for Zephyr Backpack Vacuum

The Tornado Pre-Filter for Zephyr Backpack Vacuum sits ahead of the main filter and takes the first pass at incoming debris. As you move from carpet to hard floors, it traps coarse dust and grit before that material can pack into the primary filtration stage. This can help support steadier airflow and consistent suction throughout your cleaning route. It also extends the working life of the main filter, cutting how often you have to replace it. You can complete routine filter upkeep with a quick swap between jobs, limiting downtime. Part number K28894190.
