H11 HEPA filters are designed to capture at least 95% of particles that are 0.3 microns in size. They are considered a lower grade within the HEPA classification system, which ranges from H10 to H14. Here’s how H11 filters compare to other HEPA grades:
H10: Captures about 85% of 0.3-micron particles. Suitable for basic air purification needs but less effective than H11.
H12: Captures at least 99.5% of 0.3-micron particles. Offers better filtration than H11 and is often used in medical and industrial applications.
H13: Captures at least 99.97% of 0.3-micron particles. Commonly used in healthcare settings and high-efficiency air systems,
H13 filters provide superior protection.
H14: Captures at least 99.995% of 0.3-micron particles. This is the highest grade in the HEPA classification and is used in critical environments, such as cleanrooms.
while H11
HEPA filters provide good filtration for general use, higher grades like H12, H13, and H14 offer improved particle capture rates, making them better suited for environments requiring stringent air quality standards.
