Common Features of HEPA Filters (like the ROYAL F-21)

High-Efficiency Filtration:
- HEPA filters are designed to capture at least 99.97% of particles that are 0.3 microns or larger in size. This means they are excellent for trapping allergens like dust, pollen, pet dander, and even fine particles like smoke.
Filter Lifespan:
- Typically, HEPA filters need to be replaced every 6 to 12 months depending on the usage and air quality of the environment. Some models might have indicators to show when it's time to replace the filter.
Compatibility:
- Ensure the filter is compatible with your air purifier model. In the case of the ROYAL F-21, it would typically fit specific air purifier models from ROYAL. Check the user manual for exact compatibility.
Air Flow Resistance:
- Filters with high-efficiency media like HEPA can sometimes increase the resistance to airflow. This is something to keep in mind when evaluating performance and energy consumption, as higher resistance may require more energy to maintain airflow.
Filter Material:
- HEPA filters are usually made of densely woven fiberglass. The ROYAL F-21 filter may have additional layers or features like activated carbon to address odors or chemicals.
