Maintenance Tips

• Vacuum exterior intake regularly: Clean the 360° grille to prevent dust buildup and maintain strong airflow
• Keep clearance (4–6 inches): Ensures proper air draw and even distribution of clean air
• Run continuously (best practice): 24/7 use improves particle + odor removal and stabilizes carbon performance
• Do NOT wash or open filter: Sealed HEPA + activated carbon + zeolite cartridge is not reusable or serviceable
• Maintain pre-filter via vacuuming: Light exterior cleaning helps extend main filter life
• Avoid moisture/humidity exposure: Protects carbon/zeolite adsorption efficiency
• Watch performance signs: Returning odors, reduced airflow, or dust bypass indicate saturation
• Replacement cycle: Typically up to ~5 years, depending on air quality and usage intensity
• Install correctly after replacement: Always run on high for 1–3 hours after installing a new filter to condition carbon
