Maintenance and Cleanliness

Before considering any major changes to HVAC systems, filtration, or other mitigation technology, the first thing all buildings should do is review their mechanical maintenance and cleaning procedures. Make sure that your air filters are being replaced on a consistent basis. Routine maintenance should be more frequent and should regularly include an inspection of the cleanliness of the system’s entire air path. If your building has been at low or no-occupancy for the past few months, include an indoor air quality (IAQ) analysis in your transition plans. Transition periods are also ideal times to thoroughly clean air ducts and vents.
