Cleaning Tip #2
For cleaning your cleanroom, make sure you have the right equipment. Minuteman offers a complete line of critical care vacuum for cleanroom applications. Do you know the difference between HEPA and ULPA filtration?
High efficiency particulate air (HEPA) filters and ultra-low particulate air (ULPA) filters are air filters designed to trap a vast majority of very small particulate contaminants from an air stream. HEPA & ULPA Filters are similar in many aspects, but they differ in many aspects either. Now let's learn following information about HEPA VS ULPA filters.
First and foremost, HEPA & ULPA Filters are different in definition and efficiency. HEPA filters are capable of removing 99.97% of contaminant particulates 0.3 μm in diameter. Most standards also specify that HEPA filters must feature minimal pressure drop and maximum airflow when in operation. ULPA filters are closely related to HEPA filters but are even more efficient. ULPA filters are specified to remove 99.999% of contaminants 0.12 μm or larger in diameter.
Last but not least, HEPA & ULPA Filters share similar applications. HEPA and ULPA filters are used in applications requiring very efficient filtering of airborne pathogens which can cause aggravate asthma and cause allergies or disease. These filters are also useful in manufacturing environments which require very clean air. Some applications include airline cabin air purifiers, biomedical air filtration, electronics manufacturing, pharmaceutical manufacturing and vacuum cleaner filters.
