Compact TriStar Dome Motor ...
$6.99
Product details
This replacement dome motor filter fits Compact and TriStar canister vacuums, including the C4 and C7 models, providing exhaust filtration that keeps the air clean and shields the motor from dust. It also carries part #LF-3H.
As the filter fills with fine dust it chokes airflow, which softens suction and lets particles drift toward the motor. Swapping in a fresh dome filter every six to twelve months, or whenever it looks dirty, keeps airflow open and the machine running efficiently.
- Fits: Compact and TriStar canister vacuums, including C4 and C7
- Function: Dome-shaped motor and exhaust filter
- Benefit: Clean air output and protection for internal components
- Tip: Replace every six to twelve months or when visibly soiled
Compare the shape and fit to your old filter before ordering. A fresh dome filter keeps suction steady and the motor protected.
