Choosing the correct hepa filter is one of the most important decisions when designing or upgrading a clean room. The quality of air inside your facility directly affects product safety, regulatory compliance, and operational efficiency. Whether you are working in pharmaceuticals, electronics, biotechnology, or healthcare, the right filtration system ensures your clean room performs at its best.
At Rayshen Environmental Pvt. Ltd., we help industries select and install advanced filtration solutions tailored to their needs. This guide explains how to choose the right HEPA filter for your clean room and how it works together with other essential systems.
Understand Your Clean Room Classification
The first step in selecting the right hepa filter is understanding your clean room classification. Clean rooms are classified according to ISO standards based on the number of particles allowed in the air.
For example:
- ISO Class 5 requires extremely low particle levels
- ISO Class 7 or 8 allows slightly higher limits
Higher-class clean rooms require higher efficiency HEPA filters. Rayshen evaluates your process requirements to recommend the correct filtration grade.
Choose the Correct HEPA Efficiency Level
Not all HEPA filters offer the same efficiency. Standard HEPA filters remove 99.97% of particles at 0.3 microns, while higher grades such as H13 and H14 provide even greater filtration.
For pharmaceutical and electronics clean rooms, higher-grade hepa filter options are often necessary to meet GMP and ISO standards. Rayshen supplies certified filters that match your clean room’s needs.
Consider the Airflow System
A hepa filter does not work alone. It is part of a larger airflow system that includes ffu units and air handling equipment. The filter must match the airflow capacity of your system to ensure proper performance.
When installed inside a fan filter unit, the HEPA filter delivers clean, laminar airflow directly into the workspace. Rayshen designs FFU systems that distribute air evenly across the clean room.
Evaluate Room Size and Air Change Rates
The size of your clean room and the number of air changes per hour (ACH) determine how many HEPA filters or FFUs you need. Larger rooms or higher contamination risks require more filtration coverage.
Rayshen conducts airflow calculations to ensure your clean room maintains consistent cleanliness throughout the space.
Check Filter Testing and Certification
Always choose HEPA filters that are individually tested and certified according to EN1822 or ISO standards. This ensures the filter meets the required efficiency and performance levels.
Rayshen provides fully tested and validated HEPA filters to guarantee compliance and reliability.
Integrate Supporting Clean Room Equipment
A HEPA filter works best when supported by other contamination-control systems.
Air Showers
An air shower removes dust and particles from personnel before they enter the clean room, reducing the contamination load on your HEPA system.
SS Sink for Hygiene
An ss sink installed in gowning areas allows proper handwashing, preventing microbes from entering the controlled environment.
Complete Clean Room Equipment
Rayshen offers integrated clean room equipment solutions, including HEPA filters, FFUs, air showers, SS sinks, and modular clean room systems.
Plan for Maintenance and Replacement
HEPA filters require regular inspection, testing, and timely replacement. Choosing a filter with easy access and compatibility with your FFU system makes maintenance simpler and cost-effective.
Rayshen designs systems that allow quick filter changes without disrupting operations.
