Use Case

The Kirby Bag Guard Star KB21R is essential for Kirby G-Series owners experiencing dust leakage, reduced suction, or loose bag fit. When the original seal degrades or cracks, dust escapes into the motor housing and exhaust, compromising air quality and vacuum performance. This replacement guard restores the airtight seal, preventing premature filter clogging and motor contamination. Ideal for households and facilities that rely on Kirby's legendary cleaning power and need to maintain optimal filtration and airflow integrity.
