The replacement schedule depends on factors like filter type, facility size, and air quality conditions. As a general guideline:

• Standard pleated filters (MERV 8-11): Every 3-6 months

• High-efficiency filters (MERV 13-16): Every 2-4 months

• Specialized filters (HEPA, ULPA): Follow manufacturer recommendations
  For facilities with high dust or airborne particles, more frequent changes may be needed.

The Minimum Efficiency Reporting Value (MERV) rating measures a filter’s ability to capture particles:

• MERV 8-11: Ideal for offices, schools, and retail spaces

• MERV 13-16: Recommended for hospitals, industrial sites, and high-traffic areas

• HEPA & ULPA Filters: Required for clean rooms, laboratories, and medical facilities
  Our team can help you choose the right filter based on your facility's needs.
