Q: Can filter media be reused after washing?
A: Only pre-filters (≤G4 rating). Washing damages mid/high-efficiency fibers - replace regularly.
Q: When to replace filter media?
A: Replace immediately if:
Airflow drops >30%
Visible darkening of media
PM2.5 penetration >5% (per monitors)
Maintenance Guidelines
Monthly Check: Measure light transmittance with lux meter (new media baseline: 85%)
Quarterly Cleaning: Reverse compressed air purge (≤0.3MPa pressure)
Storage: Protect from light/moisture at 15-25℃, ≤60% humidity
