Kirby Avalir Allergen Bag

These bags are specifically designed for Kirby models requiring the 205814A specification. While they fit many modern Kirby systems, we recommend checking your vacuum's manual or current bag model number to ensure a perfect fit.

HEPA 13 filtration is significantly more effective at trapping microscopic particles like pet dander, pollen, and fine dust. Standard bags often allow these smaller allergens to pass back into the air, whereas these bags capture and contain them.

Not at all. These bags are engineered to maintain optimal airflow even while capturing fine particles. In fact, replacing a full or clogged bag with a fresh one will likely restore or improve your vacuum's suction performance.

For households with pets or allergy sufferers, it is best to replace the bag when it is about two-thirds full or if you notice a decrease in suction. Replacing the bag regularly prevents the motor from working harder than necessary and keeps your home's air quality consistent.

Installation is identical to standard Kirby bags. Simply ensure the bag collar is securely seated on the vacuum's intake port to create an airtight seal, which prevents dust from leaking during operation.
