• Best For: Facilities and homes running Sanitaire upright vacuums - Boss, Genesis, Signature, LiteSpeed and Whirlwind models - where allergen control matters.
• Highlight: True HEPA-grade filtration captures the fine dust and allergens that standard filters pass back into the air.
• Expert Note: Swap in the 61840 on a set schedule in allergy-sensitive accounts like schools and healthcare, or whenever suction drops - a clean filter keeps airflow at full strength.
