Frequently Asked Questions
How often should I replace this filter?
Replacement intervals depend on usage and air quality. Most Surgically Clean Air filters last 6-12 months under normal conditions. Your unit's indicator light will alert you when it's time for a replacement.
Is this an OEM (genuine) replacement?
Yes. All filters sold here are factory-spec replacements built to the same standards as the originals shipped with your unit. Generic filters may not meet our HEPA certification or warranty requirements.
Will using a third-party filter void my warranty?
Only genuine Surgically Clean Air filters maintain warranty coverage. Third-party filters may not meet the airflow + capture specifications your unit was engineered for.
How do I install a replacement filter?
Each filter ships with installation instructions. The process typically takes under 5 minutes — power off the unit, open the filter compartment, swap the old filter for the new one, and reset the filter indicator. No tools required.
