How to Choose and Care for Filters
These points help you choose filters that fit and keep working.
Match your exact model
Cordless vacuum parts are model-specific. Check the model number on the label under the bin or on the wand before ordering, and read the fit notes on the listing.
Pre-filter vs. post-motor filter
The pre-filter catches dust before the motor; the post-motor or HEPA filter traps fine particles before air leaves. Replace both for best results.
Signs you need a new filter
Weak suction, a burning smell, a pulsing motor or a filter that stays dark after washing.
Genuine vs. third-party
Genuine parts guarantee fit and finish. Third-party parts cost less and often fit well, but quality varies, so read recent reviews for your model.
Care extends part life
Rinse washable parts in cool water and let them dry for at least 24 hours. Never use a hair dryer or heater, which can warp plastics and damage filter media.
Filter Care Routine
Keep filters fresh:
- Tap out dust outdoors weekly.
- Rinse washable filters monthly.
- Dry 24 hours before reinstalling.
- Rotate a spare set.
