Product details
This replacement Secondary Filter for the Nutone CV450 central vacuum measures 13 inches in diameter and is also cataloged as part #84129000. It adds a stage of filtration that protects the motor and helps the system hold its suction.
As a secondary filter loads with fine dust, airflow through the unit falls and the motor loses the protection this stage provides. A clogged or aged filter shows up as weaker suction throughout the house. Fitting a fresh filter restores maximum airflow and keeps the motor shielded from fine debris.
- Fits: Nutone CV450 central vacuum (13-inch diameter)
- Part: secondary filter, also #84129000
- Benefit: protects the motor and maintains suction
- Tip: replace annually or when visibly dirty
Seat the filter squarely in its housing so it sits flat, then close the unit. Clean filtration here keeps suction strong at every inlet in the home.
