What are the Working Principles of the HEPA Fan Filter Unit?
Generally speaking, a HEPA Fan Filter Unit is integrated with a control system, 99.99 percent efficient HEPA Filter, and 30 percent efficient ASHRAE.
It also includes a spin-put centrifugal fan that offers a volume adjusting facility. These all components work together to maintain the containment in the environment.
This unit work on four basic stages and those stages are:
It works against heavy and large particles that are suspended in the flow stream.
Due to viscous fluid, the little particles do not stay in one place but diffuse with the fluid stream. This diffusion process catches the smaller particles.
After diffusion, the direct interception process works; it catches mid-sized particles that are left by the inertial impaction and diffusion process.
These particles are oversized than those captured in the diffusion process but smaller than inertial impaction.
In the end, the sieving process works; it is a common method in the filtration process that is activated when the unwanted particles are large enough and unable to fit between the fiber spaces.
Working Principle of HEPA FFU

HEPA Fan Filter Catch Air Borne Microorganisms
How Can you Determine How Many HEPA Fan Filter Units are Required for your Cleanroom?
While installing a HEPA Fan Filter Unit, the first factor that you need to consider is air-change per hour (ACH), or you can call it air-change rate (ACR).
The number of times the air is filtered in one hour, known as the air change rate of the building or chamber.
To determine the number of fan filter units for a cleanroom, you also need to figure out the dimension of the cleanroom (L x W x H) as well as the ISO Classification.
Every different ISO class has a different range of air changes or air changes per hour (ACH).
After estimating the ACH, you can use the given formula to determine the number of HEPA Fan Filter Unit.
No. of FFUs = (Air Changes/Hour ÷60) x (Cubic ft. in room÷ CFM*).
Note: the CFM varies for every class, so you can put the calculated figure at the place of it.
Advance Technology FFU
How Often Do you Need to Change the Pre-Filter of your HEPA Fan Filter Unit?
The lifespan of the HEPA filter and prefilter depends upon the ambient conditions.
A pre-filter captures the large particles of the air in a bulk quantity, so it gets dirty easily. If it is installed in a dirtier environment, you are supposed to replace it within one to three months.
If you delay for pre-filter replacement, it will badly impact the blower motor as well as HEPA FFU’s output airflow.
However, besides the pre-filter, you also need to switch the HEPA filter after every 2-3 weeks.
The worn-out pre-filters and HEPA filters are unable to clean the air efficiently; thus, you need to clean them once a month and replace them according to the said time period.

Air Handling Unit Working Principle
How Long Does a HEPA Fan Filter Unit Last?
The HEPA Fan Filter Unit has a three to five years life; still, many manufacturers recommend changing the unit after every two years, no matter how new it looks.
If you do not replace a worn-out unit, your cleanroom (applications) air will not sterilize accurately; the environment will remain dirty; eventually, the entire system will collapse.
So, the timely replacement can save you from the cleanroom shutdowns and extra cost.
The lifespan of HEPA FFU depends upon several factors:
Total Operating Time
If you use your HEPA Fan Filter Unit for 24 hours a day, its life will be less than the filter that you seldom use.
Fan Speed Setting (Airflow Rate)
The life of the filter unit also depends upon its speed setting; if you use your HEPA FFU at maximum speed, it will wear out earlier than the unit that is being used at a slower speed.
It includes the condition of air and moisture of the surrounding where this unit is installed. If the surrounding air is moisture and dirtier, it will wear out earlier, and its lifespan will become shorter.
Regular maintenance can increase the life of a unit.

Can HEPA Fan Filter Unit Capture Covid-19?
HEPA Fan Filter Unit plays a vital role in killing microorganisms, even the COVID-19 virus. It dramatically lowers the number of small airborne particles in the air, making the environment safer to breathe in locations where it is installed.
A HEPA (High-Efficiency Particulate Air) filter captures particles as small as 0.3 microns with 99.99 percent efficiency, but SARS-CoV-2 is 0.12 microns in size, so it doesn’t catch a huge portion of these larger particles.
Yet it captures a sufficient portion via direct impact, diffusion, and interception processes and makes the environment safe to stay.
When COVID-19 attaches to larger specks, such as large drops or dust, this efficient unit captures the virus as well as some of the larger particles and makes the air pure. So, wherever this tiny motorized unit is installed, users remain safe from illness.
Due to these useful features, it is being vastly installed in hospital halls, patient rooms, and many other areas to control the contamination.
These medical air filtering systems can be installed in the ceiling to generate negative pressure ventilation, such as in an isolation room.
