Deiiang's high-efficiency HEPA filters are core components used in cleanrooms to purify the air.
High-efficiency particulate air (HEPA) filters can be used with air handling units, temperature and humidity control units, and large central air conditioning systems to provide clean air for cleanrooms, laboratories, hospitals, factory workshops, and more.
Deiiang helps customers meet ISO, GMP, and healthcare air quality requirements, while maintaining stable airflow circulation and controllable operating costs, thanks to its stringent third-party certifications, leak testing, and factory reports.
Our professional team provides a one-stop, customized supply of cleanroom HEPA filter to meet your specific requirements.
Deiiang aims to design and create cleanbooths products that offer high cleanliness, superior quality, intelligent operation, low energy consumption, and low noise.
Our production team runs independent lab inspections for every finished filter unit. This delivers reliable particle capture performance hitting 99.95% up to 99.995% for tiny airborne particles sized 0.1 to 0.3 microns.
Unfiltered bypass air will easily ruin controlled cleanroom classifications, so we developed three practical sealing structures for site selection: gel seals, standard gaskets, and knife-edge frames. All variants block stray air from slipping past filter edges once fully mounted.
V-bank folded layouts greatly enlarge the usable media area inside each filter. Ventilation fans won’t operate at overload to push sufficient air volume, cutting recurring power expenses month by month.
No matter which cleanroom air systems you deploy, our diverse HEPA filter lineup fits your unique site demands. Box, V-bank and heat-resistant variants work seamlessly with air handling units (AHUs), FFUs and ceiling grid frameworks.
Heat curing ovens and routine disinfection cycles are standard across many manufacturing plants. Our tailor-made HEPA units adopt reinforced housings paired with red silicone or ceramic sealants, keeping stable performance through long-duration high-heat operations.
Complete verified records are mandatory during third-party factory audits. We supply serial-number tagged leak scan test documents on demand, and all filed paperwork meets formal ISO and GMP compliance standards.
Thin lightweight frames warp easily under unstable workshop temperature and humidity. Our heavy-duty anti-corrosion housing stays dimensionally stable over time, extending service cycles and cutting replacement frequency.
We offer far more than just HEPA filter product supply. The Deiiang Cleanroom team supports your whole project lifecycle. Our specialists pick matching filter models and deliver on-site practical advice during field installation processes.
Cleanroom air handling units are generally equipped with pre-filters and high-efficiency filters, but these two types of filters serve very different purposes. The purpose of the pre-filter is to intercept large particles (dust, fibers, and hair, etc.) at the air inlet, preventing clogging of the ducts and HEPA filters in the subsequent air handling unit. HEPA filters are located at the end of the airflow process. They intercept and filter ultrafine particles and microorganisms, contaminants that pre-filters cannot intercept and that directly affect the cleanliness level. To break it down quick: pre filters maintain smooth system operation and let your HEPA filters last far longer. HEPA filters meanwhile generate traceable clean air records you’ll need to present to auditors.
Particle Size and Efficiency: It traps micro particles, bacteria and airborne aerosols from 0.1 to 0.3 μm. Our certified H13 and H14 grades deliver 99.95% to 99.995% removal efficiency.
Role in the System: HEPA filters are installed at the end of multi-stage filtration systems. The step-by-step particle interception process ensures strict air cleanliness standards, perfectly fitting the demands of GMP production areas and medical environments.
Particle Size and Filtration Efficiency: This filter captures larger debris such as dust, hair, fabric fibers, and small insects. Its filtration efficiency is low to medium, but it can handle large dust particles entering the room, thus reducing the workload on downstream filters (such as HEPA filters).
Role in the System: The primary filter is installed at the upstream air inlet of the AHU; its function is simple yet extremely important. They protect pipe coils and downstream medium- and high-efficiency filters from clogging and damage in the early stages of AHU operation, as these higher-grade filters are more expensive.
The Deiiang H13/H14 HEPA filter has traceable test reports, facilitating compliance with stringent GMP inspections. It helps control active particulate matter in GMP Class A-C rooms, supporting pre-filtration for aseptic filling.
High-efficiency filters installed in the ceilings of operating rooms and intensive care units filter out airborne contaminants, reducing the possibility of infection transmission. They meet the stringent requirements of hospital accreditation inspections.
When used with an FFU, V-bank HEPA filters achieve a balance between filtering particulate matter and pressure drop, consistently maintaining cleanroom cleanliness.
HEPA filters installed in the filling area not only prevent HVAC overload but also help reduce the risk of contaminants such as dust, achieving cleanliness goals.
Deiiang HEPA filters can be installed in AHUs and biosafety cabinets to protect the experimental environment from airborne contamination during operations. They also make maintenance and replacement predictable.
Gel seal HEPA filters with knife‑edge frames minimize leakage in high‑risk corridors and containment rooms, giving reliable data for ISO and GMP requalification.

Deiiang HEPA filter Quality Control Flowchart
Don’t wash your HEPA filter at all. Cleaning can deform the filter media, create gaps, and reduce filtration efficiency. In most cases, dust cannot be completely washed away.
A damp filter saturated with moisture also becomes a breeding ground for mold and bacteria. For these reasons, manufacturers and standards bodies recommend replacing, not washing, HEPA filters.
HEPA filters are designed to capture particles, not gases. They cannot remove gases, volatile organic compounds (VOCs), fumes, or many odor molecules. Very ultrafine smoke particles may also pass through.
While HEPA filters can intercept most bacteria and droplets carrying microorganisms, they do not kill them. If you need gas‑phase removal or sterilization, you must add activated carbon, chemical filters, or UV/other disinfection technologies.
The EN 1822 standard classifies high‑efficiency filters into H10–H14 (HEPA) and U15 and above (ULPA). H13 removes 99.95% of 0.3 μm particles, and H14 removes 99.995% at the most penetrating particle size (MPPS).
Standard HEPA filters also meet the U.S. Department of Energy (DOE) requirement of at least 99.97% efficiency at 0.3 μm. In cleanroom projects, H13 and H14 grades are most commonly used.
H13 HEPA filters capture at least 99.95% of particles ≥0.3 μm according to EN 1822. They are widely used in laboratories, hospitals, and many pharmaceutical cleanrooms where high, but not ultra‑extreme, air cleanliness is required.
H13 filters are also compatible with ISO 14644‑1 cleanroom classifications and are often selected as terminal filters in ISO 5–7 areas, depending on process risk and regulatory expectations.
A HEPA filter’s rating (for example H13 or H14) indicates its certified filtration efficiency at the most penetrating particle size. H13 and H14 are commonly used in industrial cleanrooms and critical HVAC systems.
These ratings show how effectively the filter blocks fine particles and microorganisms in environments such as medical facilities, pharmaceutical plants, electronics factories, and high‑tech production lines. Each rating fits different air purity demands, from general clean areas to strict cleanrooms.
HEPA filters are used wherever very clean air is required. Typical applications include cleanrooms, laboratories, hospitals, operating rooms, isolation rooms, and high‑tech manufacturing.
They are also integrated into air handling units, air purifiers, and high‑end vacuum cleaners to improve indoor air quality in commercial buildings and some residential settings.
HEPA filter prices vary with size, grade (H13, H14, etc.), frame structure, and intended use. Smaller or basic units can range from around $100–500, while large industrial cleanroom HEPA filters may exceed $1,000 per piece.
When budgeting, also consider recurring costs such as pre‑filters, installation labor, leak testing, and periodic replacement, as these often exceed the one‑time purchase price over the life of the system.
Standard installation costs can be roughly $200–500 per filter in typical commercial systems, depending on access, height, and safety requirements. Complex air handling units, custom housings, or cleanroom retrofits usually cost more.
For regulated projects, factor in additional expenses for leak testing, balancing, and validation in line with ISO 14644‑2 and other relevant filtration and HVAC standards.
HEPA filters use high‑grade filter media, precise pleating, and robust frames, and many units undergo individual leak testing and third‑party certification. All of this adds material, labor, and quality‑control cost.
However, this rigorous process ensures that each filter truly meets its rated performance, which is critical for pharmaceutical, healthcare, and high‑tech applications where product safety and regulatory compliance are non‑negotiable.
For cleanrooms, hospitals, and critical manufacturing, HEPA filters are usually essential and well worth the investment. They reduce contamination risk, support ISO and GMP compliance, and help you pass audits.
Their stable performance and extended service life, especially when combined with proper pre‑filtration, often offset the higher initial price by reducing product losses, downtime, and regulatory issues.
How to Select the Right HEPA Filter
First, lock down your air cleanliness rules
List your ISO grade, GMP or medical rules plus key zones like operating rooms and semiconductor workshops. These details set whether you need H13 or H14 HEPA Filter, full leak tests and official compliance papers.
Next, pick matching HEPA efficiency levels
H13 works for regular pharmaceutical and medical terminal points. Pick H14 for sterile, high-risk spaces. Always ask makers for full test records covering efficiency, MPPS and pressure loss.
Don’t skip airflow and pressure loss checks
Hand over your planned air volume and acceptable system pressure. Mini-pleat or V-bank cuts airflow resistance, easing fan load and trimming power bills long term.
Choose the filter model suitable for your installation location
Installation locations include AHUs, FFUs, ceiling mounts, and high-temperature areas. Depending on your specific installation needs, you can choose gel-sealed, gasket-free, V-type, or high-temperature resistant filters.
Pay attention to the on-site conditions
The use of high temperatures, steam sterilization, or strong chemical disinfectants will have some impact on the choice of frame materials (aluminum or stainless steel) and adhesives.
Never skip pre-filter setups
Adding pre and medium filters greatly stretches your HEPA Filter lifespan. Match multi-stage filtration to local dust levels to cut running costs.
Properly maintain test records for future audits
Larger, regulated projects typically require leak testing and factory documentation for each filter unit to pass subsequent Installation Qualification/Operational Qualification (IQ/OQ), ISO, and GMP inspections.
