ULPA Filters: Your Top Questions Answered
For over 20 years, WuJiang DeshengXin Purification Equipment Co., LTD has engineered ultra-high-efficiency air purification solutions. Below, we address the most critical questions about ULPA filters to help industries achieve unmatched air quality.
1. What is a ULPA Filter?
A ULPA filter (Ultra-Low Penetration Air Filter) is a mechanical air filter designed to capture 99.9995% of particles as small as 0.1–0.2 microns, including viruses, bacteria, and ultrafine dust. Developed for environments demanding extreme cleanliness, such as semiconductor manufacturing and pharmaceutical labs, ULPA filters exceed the efficiency of standard HEPA filters by targeting smaller contaminants
2. How Do ULPA Filters Differ from HEPA Filters?
| Feature | HEPA Filters | ULPA Filters |
Particle Capture | 99.97% of ≥0.3μm particles | 99.9995% of ≥0.1μm particles |
Applications | Hospitals, homes | Cleanrooms, labs, microelectronics |
Standards | EN 1822 (H13/H14 grades) | IEST-RP-CC034, ISO 29463 |
Lifespan | 6–12 months | 8–18 months (with pre-filters) |
ULPA filters use tighter fiber arrangements and larger filtration areas to achieve superior performance.
3. What Are the Key Benefits of ULPA Filters?
Critical Contaminant Removal: Eliminates 99.9995% of airborne pathogens, nanoparticles, and chemical residues.
Industry Compliance: Meets ISO Class 3–5 cleanroom standards for semiconductor and biotech sectors.
Energy Efficiency: Low-pressure drop designs reduce HVAC energy costs by 20–30%.
Customizable: Available in stainless steel, aluminum, or galvanized frames for corrosive environments.
