HEPA (High Efficiency Particulate Air)
Designed to capture very small particles with a high level of capture efficiency, HEPA filters are commonly used in various applications, including home ventilation systems, air filtration units, and air protection equipment in environments such as laboratories and healthcare facilities.

ULPA (Ultra Low Penetration Air)
ULPA filters have a higher level of capture efficiency compared to HEPA filters. They can capture very small particles, even smaller than those that HEPA filters can capture. ULPA filters are often used in environments that require an extremely high level of air cleanliness, such as in the semiconductor industry or high-level research laboratories.
