Today, as global air purification undergoes an upgrade, PM2.5 is no longer the sole standard for purification. Households, hospitals, schools, and office spaces are increasingly concerned about ultrafine particles, bacteria, and viruses. While traditional HEPA filter technology is mature, it struggles to effectively capture the PM0.01–PM0.3 size range - the "most penetrating and most harmful" particle fraction. Nairteng Full Particle Size Purification, powered by the triboelectric nanotechnology developed by the Chinese Academy of Sciences, fundamentally overturns the traditional physical interception model, achieving full coverage from PM0.01 to PM10, and becoming a core competitive advantage for export to high-end markets such as Europe, the United States, and the Middle East.
Traditional HEPA filters rely on three physical mechanisms - inertial impaction, interception, and diffusion - to capture particles. For particles above PM0.3, the efficiency is acceptable. However, when particles are smaller than PM0.1 or even down to PM0.01, their diffusion capacity increases while their inertial mass decreases, causing the capture probability to drop sharply. This is the fundamental reason for HEPA's "efficiency gap" with ultrafine particles.
More critically, as a physical sieve, HEPA filters experience exponentially increasing airflow resistance as particles accumulate. Fan power consumption rises, noise increases. Meanwhile, captured bacteria and mold can multiply on the damp filter media, creating secondary pollution. This attenuation characteristic of "dirtier and noisier over time" clearly cannot meet the overseas customer demand for long-term stability, safety, and health.
The core breakthrough of Nairteng lies in its triboelectric nanotechnology. Its purification unit is made of a special nanocomposite material. As air flows through, the kinetic energy of the airflow stimulates the material's surface to generate a continuous, stable, weak electrostatic field. This field is not the high-voltage ionization used in traditional electrostatic precipitators, but rather a low-voltage, high-field-strength, zero-ozone adsorption field.
This electric field exerts Coulomb force on moving particles in the air (regardless of particle size), actively pulling them toward the collection electrode where they are firmly adsorbed. The key point is that this electric field force is independent of particle size - even ultrafine particles of PM0.01, as long as they carry a微量 charge or have polarization properties, can be efficiently captured. Therefore, Nairteng achieves true full-size, indiscriminate purification from PM0.01 to PM10, completely addressing the shortcomings of HEPA with small particles.
Furthermore, the electric field creates an electroporation effect on the envelopes and protein structures of bacteria and viruses, simultaneously inactivating pathogens with a removal rate of 99.99% - something pure physical interception cannot achieve.
Traditional HEPA filters must be replaced once saturated. In contrast, Nairteng's dust collection components are made of washable nanomaterials. Users can periodically remove them, rinse them directly with water, and after drying, they restore to initial efficiency without any performance degradation. This feature thoroughly solves two major pain points in overseas markets:
Operating cost: Zero consumable expenditure, no need for frequent filter purchases.
Environmental compliance: Meets the increasingly stringent e-waste and plastic reduction regulations in the EU and North America.
Meanwhile, because it does not rely on a dense filter media, Nairteng equipment has extremely low airflow resistance, allowing it to pair with smaller power fans to achieve low noise and low energy consumption, making it suitable for quiet environments like bedrooms, hospitals, and libraries.
The two most sensitive risks for air purifiers in overseas markets are ozone and electrical breakdown. Nairteng's triboelectric nanotechnology operates at voltages far below the ozone generation threshold, and testing by SGS and other authoritative institutions has confirmed zero ozone release, fully complying with standards such as CARB, CE, and RoHS. Compared to certain electrostatic precipitators, Nairteng carries no risk of secondary pollution and can be safely used for sensitive populations including infants, the elderly, and asthma patients.
Nairteng Full Particle Size Purification is not merely a selling point - it is the core technology of purification products. It fundamentally solves the three major problems of traditional filters - "can't filter fine enough, can't filter long enough, can't filter safely enough" - achieving full-size, around-the-clock, zero-consumable efficient purification through active electric field adsorption.
