Four things that decide whether a filter is any good
Media, construction, process control and accountability — in that order.
Imported media
Core media is imported from the US, Korea and Germany or sourced from leading domestic makers, with defined efficiency and initial restriction figures.
Patented construction
The group holds over 100 invention and utility-model patents covering dual-layer media, pleat design and end-cap sealing.
Systematic quality control
Incoming, in-process and outgoing inspection to IATF 16949, with batch sampling of key dimensions and pressure drop.
Liability insured
The full range is covered by CPIC product liability insurance with a three-guarantee commitment.
Audited, not self-declared
The factory is certified to the same automotive quality standards its OEM customers require. We can share certificates and test reports on request.

What every filter in the range shares
Dual-layer media
Dual-layer media filters coarse to fine in stages, giving lower restriction, higher dust capacity, longer life and better moisture resistance.
Traceable media sourcing
Lube and fuel media is sourced from US and Korean suppliers such as HV and Ahlstrom — high efficiency with low initial restriction.
Built to OE specification
Construction machinery elements are built to original OE standards to protect intake cleanliness and reduce engine wear.
Seals and end caps
Oil- and heat-resistant end-cap adhesive with properly rebounding seals avoids the classic “new filter still weeps” problem.
Antibacterial options
Nano-silver antibacterial fibre layers inhibit E. coli, S. aureus, C. albicans and others, with third-party test reports available.
Warranty and liability cover
Every product carries a three-guarantee commitment and CPIC product liability insurance; defects are replaced or refunded.
