What is the emission of National Five and Six air filters?

Core differences between National V and National VI air filters

​Improved Filtration Efficiency Requirements

National VI standards tighten PM (particulate matter) emission limits by about 30%, requiring air filters to have stronger particle capture capabilities, especially for fine particles below 0.3μm, the filtration efficiency must be ≥95% (National V is ≥90%). Some high-efficient filters use multi-layer composite fiber materials or electrostatic electret technology to meet the standards.

​Enhanced High Temperature Resistance And Chemical Stability

To improve fuel economy, National VI requires intake resistance ≤2.5kPa (National V ≤3.5kPa). The filter balances filtration efficiency and air permeability through three-dimensional pleated design and low-density filter material to reduce engine intake power consumption.

Bowei Air Filter Factory recently launched a new type of heavy-duty truck air filter. They are widely applicable to major heavy-duty trucks. From Emission V to Emission VI, we can meet your needs. We are working hard to launch more and better products of this type for everyone to choose and use.
