HEPA filters trap fine particles and allergens, but they don't last forever. Here's how to know when it's time to replace yours.
When to Replace
- Every 6 months for households with pets or allergies
- Every 12 months for average households
- Immediately if the filter is visibly dirty, damaged, or emitting odors
Signs Your Filter Needs Replacement
- Reduced suction power despite a clean dust bag or bin
- Dusty or musty smell when the vacuum is running
- The vacuum motor runs hotter than usual
- Visible dirt or discoloration on the filter material
How to Replace a HEPA Filter
Locate the filter compartment — usually behind a panel on the side or back of the vacuum. Open the compartment, remove the old filter, and insert the new one with the same orientation. Most HEPA filters have an arrow indicating airflow direction — make sure it points toward the motor.
Pre-Filter Maintenance
Many vacuums have a washable pre-filter that catches larger particles before they reach the HEPA filter. Rinse the pre-filter monthly and let it dry completely before reinstalling. This extends HEPA filter life significantly.
Buying the Right Filter
Check your vacuum's model number before ordering. While some filters are universal, most are designed for specific model ranges. Our filter listings include compatibility information for major brands including Hoover, Eureka, Kenmore, and Dyson.
