12 Difference Between Hepa And Ulpa Filters

1.  A ULPA filter will remove particles with greater efficiency than a HEPA filter of the same dimensions.  2. ULPA filters are specified to remove 99.999% of contaminants 0.12 μm or larger in diameter. HEPA filters are often touted as capable of "removing 99.97% of dust and allergens" without specifying particle size. 3. HEPA: 0.3 micron filtration 0. 12 micron particle filtration. 4. ULPA: MERV 20 HEPA Filter Features: MERV 17 5. For most biomedical applications, HEPA offers more than adequate filter efficiency to protect personnel and prevent work cross-contamination. 6. HEPA: Recommended by cvc ULPA: Not Recommended by cvc 7. HEPA filters have a MERV rating of 17 and provide excellent filtration for bacteria, lung damaging dust, spores, pollen, pulverized coal, and metallurgical dust and fumes. ULPA filters provide better filtration for tobacco smoke, oil smoke, insecticide dust, carbon dust, and even capture some viruses. 8. ULPA filters are more expensive than a HEPA filter of the same dimensions.  9. ULPA filters have a shorter service life than HEPA filters, increasing maintenance costs due to more frequent replacement.
