The heart of filtration. Our electret meltblown achieves 99.97% (H13/H14) efficiency with low resistance. Ideal for HVAC, cleanrooms, and air purifiers.
More Than Just Fabric: The "Heart" of Your Filtration System
Discover how meltblown nonwoven redefines HEPA standards through micron-level fibers and electret technology.
In HVAC and air purification systems, the choice of filtration media determines energy efficiency and equipment lifespan. With its unique ultra-fine fiber structure, meltblown nonwoven serves as the critical defense line for intercepting particles.
Core Operating Principle: A Dual Defense of Physics and Electrostatics
Meltblown nonwoven relies on more than just a "sieve" effect. Acme utilizes advanced manufacturing processes to construct a 3D, charged fiber maze within the HEPA layer, employing different capture strategies for pollutants of varying particle sizes:

Physical Interception Mechanism
Target: Dust and pollen > 1μm.
Utilizes Inertial Impaction and Interception. When airflow bypasses fibers, heavier particles cannot turn due to inertia and impact the fibers; or large particles are physically trapped in the fiber gaps.

Electret Technology (Electrostatic)
Target: Viruses, bacteria, and PM0.3 < 1μm.
Combines the Diffusion effect with Electrostatic Attraction. Even tiny particles drifting with the airflow are actively attracted by the static charge on the fibers like a magnet—key to achieving HEPA-level efficiency.
