Question
Are filters with MERV rating 13 or higher installed on AHUs?
Applicability
Applicable to Office, Healthcare, Enclosed Shopping Centre, Universal and Multi-Unit Residential buildings
Answer
Description
Installation of filtration systems that meet ASHRAE Minimum Efficiency Reporting Value (MERV) 13 or equivalent prevent larger outdoor air contaminants, such as mould spores, pollen, some dusts, and aerosols from entering the HVAC system. Installation of filtration systems that meet ASHRAE MERV 13 to 16 prevent up to 90% of fine outdoor air contaminants, such as mould spores, pollen, dusts, and aerosols from entering the HVAC system.
Requirements
- Provide evidence of the MERV filter rating or equivalent. All filters must be rated as per ASHRAE 52.2
- Filters must be replaced at or before the pre-determined pressure drop or timeframe, not exceeding the manufacturer’s specifications and ASHRAE Standard 180 (Maintenance Standard)
Documentation
- Filter rating (MERV 13 to 16) or equivalent, such as via inventory list, product box, photos
- Filter replacement schedule
