Specification of Air Purification Pre Air Filter
AHU filters
This AHU filter usually has several types depending on the level of efficiency in filtering particles or dust, based on the level of efficiency the AHU filter can be divided into three types:
– Pre filter, this Pre Filter has an efficiency level of about 35 percent
– Medium Filter, has an efficiency level of filtering around 95 percent
– High Efficiency Particulate Air (HEPA), has an efficiency level of about 99 percent
The three types of AHU filters require regular replacement to keep the HVAC system working optimally so that the air produced remains cool and clean.
