Operation and Benefits
Once installed, the STANLEY 25-1228 disposable filter bag effectively captures fine particles, including woodworking debris and renovation dust. This helps maintain consistent airflow and suction power in your vacuum. The use of these bags is particularly beneficial for dry vacuuming tasks, reducing the frequency of main filter cleaning and extending its lifespan.
