Hepa Filters Vs Ulpa Filters Comparison<\/span><\/h1>[vc_column_text]Clean environments like <\/span>biosafety cabinets<\/span><\/a>, <\/span>laminar flow cabinets<\/span><\/a>, and <\/span>clean rooms<\/span><\/a> require a controlled environment free from dust, particles, and contaminants.\u00a0<\/span><\/p>\n

HEPA (high efficiency particulate air) and ULPA (ultra-low particulate air) filters are commonly used in the air filtration systems for delivering a controlled environment.\u00a0<\/span><\/p>\n

Additionally, in ULPA the airflow reduces by 20% to 50% for filters of the same dimensions. The cost of ULPA is typically higher by 25% to 35%, and life span of ULPA is 5-8 years compared to HEPA\u2019s ~10 years.<\/span>[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
