HEPA and ULPA Filters: Advantages, Limitations, and HVAC System Considerations

Choosing the wrong air filter can compromise regulatory compliance and indoor air quality (IAQ). Some facilities require more specialized air filtration than what MERV filters can provide. Industries such as pharmaceuticals, aerospace, and other critical environments need to ensure airborne contaminants are kept to a minimum. Both HEPA (High Efficiency Particulate Air) and ULPA (Ultra Low Particulate Air) filters can be suited to the task, but they are not the same thing.
