Keep airflow like new.
Cotton filters gradually lose efficiency as dirt settles into the surface. The oversock forms a serviceable first layer that captures contamination before it reaches the filter.
- Slides directly over the R600 cotton filter.
- Remove and clean—or replace—at each service.
- Helps maintain cotton-filter airflow and appearance.
PRECISION ENGINEERED FOR PERFECT PERFORMANCE.
Simply slides over the top of your Cotton R600 filter.
Single layer foam material protects debris and dust from settling on Cotton Filter surface.
Cotton Filters always deteriorate in efficiency as dust settles and slowly restricts airflow – this oversock keeps the surface clean.
Simply remove and clean, or replace at each service, keeping your Cotton Filter airflow like new.
