HEPA Filters
"HEPA filter uses ultra-fine glass fiber as the filter media and hot-melt adhesive as the separator, with various frame options.
Compared to separator HEPA filters, it is smaller, lighter, and aesthetically appealing, making it ideal for airflow-restricted applications."
Explanation
(1) Initial Airflow Resistance: The airflow resistance when a new filter is first installed, ensuring normal fan operation.
(2) Final Resistance: The resistance when the filter is near the end of its lifespan. Replacement is recommended at this stage to prevent airflow reduction and equipment performance issues.
(3) Working Air Volume: The airflow volume when working in combination with an FFU.
(4) Maximum Air Volume: The maximum airflow the filter can withstand. Exceeding this limit may cause damage or air leakage.
High-Efficiency HEPA Filters for Cleanrooms, HVAC & Industrial Applications
A HEPA filter is one of the most essential components in any contamination-controlled environment.

Understanding HEPA Filter Technical Parameters
1. Initial Airflow Resistance
This is the pressure drop measured when the filter is first installed. Lower resistance means smoother airflow and reduced fan energy usage.
2. Final Resistance
This is the maximum pressure drop a filter can handle before replacement. When the filter reaches this limit, airflow reduces and contamination risks increase.
3. Working Air Volume
This indicates the recommended airflow when a HEPA filter is used in an AHU or FFU. Correct working volume ensures maximum filtration and longer equipment life.
4. Maximum Air Volume
This is the highest airflow the HEPA media can withstand. Exceeding this limit may cause media damage or leakage.
These technical values apply across hepa filter types, including h13 hepa filter, hepa filter h13, and h14 hepa filter options available at Rayshen.

Frequently Asked Questions (FAQs)
Q1. What is a HEPA filter?A HEPA filter (High Efficiency Particulate Air filter) is a high-performance air filter designed to capture 99.97% of particles as small as 0.3 microns. It removes dust, pollutants, microbes, pollen, and other airborne contaminants, making it ideal for cleanrooms, HVAC systems, healthcare, and industrial environments.
Q2. Why is a HEPA filter important?A HEPA filter is crucial because it provides extremely pure air by trapping microscopic particles that ordinary filters cannot. This helps maintain hygiene, protect sensitive environments, and ensure clean breathing air.
Q3. What is the efficiency of Rayshen HEPA filters?Rayshen HEPA filters are crafted to provide 99.97% efficiency at 0.3 microns, ideal for cleanrooms and high-purity environments.
Q4. Which media is used in the HEPA filters?We use ultra-fine, high-grade glass fiber media with hot-melt separation for durability and enhanced dust-holding capacity
Q5. How often should I replace a HEPA filter?Typically between 12–18 months, or when it reaches final resistance, depending on usage conditions.
Q6. Can Rayshen HEPA filters be used in FFUs?Absolutely. Our filters are designed for FFU installations and maintain stable laminar airflow.
Q7. Do you offer custom sizes?Yes, Rayshen manufactures custom HEPA filter size options for AHUs, FFUs, HVAC systems, and cleanroom applications.
Q8. What is the difference between H13 and H14 HEPA filters?- H13 HEPA filter: Captures 99.95% of 0.1–0.3 micron particles
- H14 HEPA filter: Captures 99.995% of ultrafine particles H14 offers a higher level of protection and is preferred for critical cleanroom environments.
