Frequently Asked Questions

Yes. The type and condition of an HVAC filter have a direct effect on how much energy a system uses. When a filter becomes clogged, or the filter’s resistance is too high for the equipment, the system must work harder to move air. This increases fan power consumption and can strain other HVAC components. Clean, properly selected filters help maintain smooth airflow and keep energy use in check.

Schools typically achieve the best results with MERV 13 filters, which are capable of capturing smaller airborne particles such as dust, allergens, and respiratory aerosols common in busy classroom environments. These filters support healthier indoor air by reducing pollutants that can affect student performance and staff well-being. 

Most data centers replace their air filters every 2 to 3 months, though the exact timing depends on dust load, cooling design, and how hard the equipment is running. Because filters directly influence airflow across servers, waiting too long can lead to higher temperatures and increased energy usage. Many facilities track pressure drop or airflow changes to determine the ideal replacement interval instead of relying strictly on a calendar.

High Efficiency Particulate Air (HEPA) filters serve as a key barrier against airborne contaminants. They are used to maintain air quality in manufacturing, homes, workplaces and hospitals, by capturing extremely fine particles, including dust, pet dander, pollen, mold, and microorganisms. Their ability to remove nearly all particles above 0.3 microns helps support cleaner air and maintains strict cleanliness requirements.
