Product Introduction
In the world of high-efficiency filtration, air resistance is the primary enemy of energy efficiency. Our Electrostatic Fiber Filter Series, also known as HAF (High Airflow Filtration) media, provides a revolutionary solution to this problem. Unlike standard filters that rely solely on "mechanical sieving" (physically blocking particles), our electrostatic fibers utilize Permanent Static Charges to attract and trap airborne pollutants. This allows for a much more open fiber structure, providing up to 10 times the airflow of a traditional dense filter with the same efficiency rating. At Nantong Lyusen, we utilize a specialized "Corona Discharge" or "Hydro-Charging" process to embed a stable biphasic electrostatic charge deep into our polypropylene and polyester fibers. This electrostatic field acts as a "magnet" for dust, pollen, bacteria, and PM2.5 soot, pulling them out of the air stream and locking them onto the fiber surface even if the particles are much smaller than the gaps between the fibers.
What distinguishes Lyusen’s electrostatic series is the Stability and Longevity of the Static Charge. Many cheap electrostatic filters lose their charge quickly when exposed to humidity or aging. By cooperating with state R&D institutions in Shanghai and Nanjing, we have developed a "Doped Polymer" formula that shields the internal charge from environmental factors, ensuring that the filter maintains its high efficiency for its entire service life. As a high-tech enterprise certified in 2020, Nantong Lyusen provides this high-performance media in various forms, including bulk rolls for AHU maintenance, pleated panels for air purifiers, and "Cut-to-Fit" pads for home AC units. By sourcing directly from our factory, you are getting an industrial-grade "Energy-Saving" filter that significantly reduces the load on your HVAC fans, providing your B2B customers with a measurably lower electricity bill and a higher CADR (Clean Air Delivery Rate). This combination of material science and manufacturing scale makes Nantong Lyusen the leading choice for the next generation of high-efficiency, low-resistance air purification.
Detailed Technical Specifications
Technical precision and airflow data are the benchmarks of the electrostatic series. To help our B2B partners optimize their system designs, Nantong Lyusen provides comprehensive performance metrics based on the ASHRAE 52.2 (MERV) and ISO 16890 standards. We focus on the "Efficiency-to-Pressure-Drop Ratio," which is the primary technical advantage of electrostatic media. We utilize specialized "Surface Potential Meters" to verify the charge density of every batch before it leaves our factory. Below is a data matrix showcasing our primary electrostatic fiber grades and their comparative performance metrics.

Our electrostatic fibers are manufactured to be Hydrophobic and Moisture-Resistant, ensuring that the charge remains stable even in high-humidity (up to 80% RH) environments—a critical requirement for tropical markets and seaside industrial sites. We utilize high-precision Needle-Punch and Thermal-Bonding equipment in our ISO 9001-certified facility to ensure that the fiber web is uniform and non-shedding, preventing any fibers from entering the air stream. We offer custom "Lamination Options," where the electrostatic layer is bonded to a rigid support mesh or an activated carbon layer for 2-in-1 performance. Every shipment is accompanied by a Batch Test Report that confirms the filtration efficiency and the airflow resistance, providing the technical proof needed for global HVAC and air purifier certifications. By providing this level of data-driven assurance, Nantong Lyusen ensures that your products deliver the high-flow performance that modern consumers and industrial engineers demand.
Primary Industrial Applications
The primary application of our Electrostatic Fiber Filter Series is in the High-Performance HVAC and Central Air Conditioning market. In large buildings, hospitals, and shopping malls, the cost of moving air is a massive operational expense. Our low-resistance electrostatic filters allow these facilities to maintain high air quality standards (meeting MERV 13 or ePM1 requirements) while using significantly less fan power. This is the "Secret Weapon" for buildings seeking LEED or BREEAM green-building certifications. Because our media is "High-Flow," it can often be retrofitted into older AHUs that don't have the motor power to handle modern dense HEPA filters, providing a cost-effective way to upgrade a whole building’s air quality without replacing expensive hardware.
In the Consumer Air Purifier and Home AC aftermarket, electrostatic media is the "Gold Standard" for high CADR (Clean Air Delivery Rate) performance. Most top-tier air purifier brands use a layer of electrostatic media to achieve high particle capture with very low noise levels—essential for bedroom use. We also provide "Cut-to-Fit" electrostatic pads that consumers can add to their standard wall-mounted split AC units. These pads turn a simple air conditioner into an effective air purifier, capturing pollen, smoke, and PM2.5 soot that standard plastic AC screens miss. This is a massive market in East Asia (Japan and South Korea) and increasingly in North America, where wildfire smoke and seasonal allergies are growing concerns.
Furthermore, our electrostatic series is essential for Sensitive Electronics and Server Cooling. In data centers and telecommunications base stations, removing fine dust is critical for preventing overheating and electronic failure, but the cooling fans must operate at maximum efficiency. Our HAF filters provide the perfect balance—they trap the fine particulates that cause "Whisker Growth" on circuit boards while allowing a high volume of cooling air to pass through freely. We also serve the Medical and Laboratory sectors, providing electrostatic pre-filters for surgical smoke evacuators and cleanroom intakes, where they protect more expensive HEPA filters from premature clogging. From a high-tech data center to a family living room, Nantong Lyusen’s electrostatic fiber technology provides the advanced, energy-efficient solution needed for a cleaner and more sustainable future.
Core Technical Advantages
The primary advantage of Lyusen’s Electrostatic Fiber Filter Series is the Unmatched "Airflow-to-Efficiency" Ratio. In traditional filtration, if you want higher efficiency, you need a denser filter, which causes higher air resistance. Electrostatic technology breaks this "compromise." By using permanent electrical charges to "capture" particles from a distance, we can use a much more open and breathable fiber web. This allows for an Initial Resistance that is 50-80% lower than traditional mechanical filters of the same efficiency. For the end-user, this means a quieter air purifier, a faster "Clean Air Delivery Rate," and a measurable reduction in monthly electricity bills. For the B2B equipment manufacturer, it means you can use smaller, cheaper fan motors and still achieve "Premium" performance ratings.
Another major technical benefit is the Deep-Loading Capacity and Longer Service Life. Mechanical filters work like a sieve—once the surface is covered in dust, the air is blocked (Surface Loading). Electrostatic filters work through the entire volume of the media (Depth Loading). Particles are attracted to the fibers deep inside the filter, allowing the media to hold a massive amount of dust before the air resistance begins to rise. At Nantong Lyusen, we have engineered our electrostatic fibers to have a High Dust Holding Capacity (DHC), which means your customers have to replace the filters less frequently. This reduces the "Total Cost of Ownership" and minimizes the environmental waste generated by your product line, aligning with global sustainability and CSR goals.
Finally, Lyusen offers Long-Term Charge Stability and Scientific Authority. The biggest weakness of generic electrostatic filters is "Charge Decay"—the loss of effectiveness over time, especially in humid conditions. By cooperating with famous R&D institutions in Shanghai and Nanjing, we have developed a "Hidden-Charge" Biphasic technology that protects the static field at a molecular level. Our media has been tested to maintain its efficiency even after 12 months of use in real-world environments. As a "High-Tech Enterprise (2020)" with 26 years of industrial history, we provide the technical validation and "Scientific Proof" needed to win the trust of global B2B clients in the medical, data center, and automotive sectors. By choosing Nantong Lyusen, you get more than just a filter; you get an advanced material science solution that makes your air purification products smarter, quieter, and more profitable.

We also support Irrevocable Letters of Credit (L/C) at Sight, providing a secure payment framework for large-scale infrastructure or government tenders. All transactions are handled with the highest standards of transparency and international bank compliance.
Logistically, electrostatic fiber rolls are "High-Volume, Low-Weight" items. To help our clients save on international freight, we utilize Advanced Vacuum Compression and High-Density Palletization. We can compress our non-woven rolls to a fraction of their original size for ocean transit, significantly reducing the "Dimensional Weight" and allowing you to fit up to 50% more material in a 40ft High Cube container. Once the vacuum seal is broken at your warehouse, the "Elastic Memory" of the synthetic fibers allows the media to bounce back to its original loft and thickness within minutes, with zero loss in static charge or filtration efficiency. Our factory in Nantong is located near the Port of Shanghai, offering weekly sailings and competitive freight rates to Japan, Korea, Europe, and the Americas. For urgent maintenance or R&D requirements, we offer express air freight via FedEx, DHL, or UPS, with door-to-door delivery usually within 5-7 business days. To ensure the materials remain "factory-fresh" and the static charge is protected from urban smog, we use Moisture-Proof, Anti-Static PE Wrapping and reinforced export cartons. With real-time tracking and dedicated export coordinators, Nantong Lyusen ensures your critical filtration supplies arrive on time and in perfect condition, anywhere in the world.
- Q: Will the electrostatic charge in the filter "leak" or shock someone?
- A: No. The charge is "Passive" and is embedded deep within the molecular structure of the plastic fibers. It is a static potential, not a flowing current. It is completely safe to touch, and it does not produce any ozone or electromagnetic interference (EMI). It acts only like a "magnet" for dust at a microscopic level.
- Q: Does the electrostatic filter lose its efficiency if it gets wet or humid?
- A: While very high humidity (above 85% RH) can slightly reduce the efficiency of some electrostatic filters, Lyusen’s "Hydro-Charged" technology is specifically designed to be moisture-resistant. Our biphasic charges are "shielded" within the polymer matrix, ensuring that the filter maintains its high performance even in humid tropical climates or during damp summer months.
- Q: Can I wash and reuse these electrostatic filters?
- A: Generally, no. Washing the filter with water and soap can "ground" the static charge and wash away the electrostatic effect, leaving you with just a basic mechanical filter. Also, the dust is trapped deep inside the fibers (Depth Loading), making it very difficult to wash out completely. For the best air quality and energy savings, we recommend replacing the media once it reaches its dust-loading capacity.
- Q: Why is an electrostatic filter better for my air conditioner than a standard screen?
- A: A standard plastic AC screen only catches large "hair and fluff." It misses the fine pollen, smoke, and PM2.5 particles that cause allergies and health issues. Adding an electrostatic layer allows your AC to act as an air purifier, catching these tiny particles with almost zero extra resistance, so your AC stays efficient and your air stays healthy.
