Pre-filters extend the life of your VELO's HEPA filter
- Increase your Velo’s HEPA filtration capability by replacing your prefilter whenever dust accumulation is visible. 20 filter sleeves per pack.
- When using your Velo or Velo Pro HEPA Attachment for conditions where dangerous contaminants may be present, both the HEPA filter (F519) and the Prefilter (F520) should be replaced after each job to help prevent cross-contamination.
- Before installing new filters, vacuum, and damp-wipe top plate and wireframe according to current ANSI/IICRC standards for remediation.
- Remove filters and clean the unit before removing it from the containment area to avoid cross-contamination.
- Allow the unit to dry before installing clean filters.
