Product Quality

Top-Notch Quality Control

Herrick Filter's design may be copied but Never the Quality. The goal of our Quality Control Program is to insure that the filters leaving our facility are consistently of the highest quality we are capable of producing. The program features test which defines functional performance of the product in various angles. Raw materials are thoroughly inspected and tested in our laboratory to insure that they meet our demanding specifications. Materials that don't measure up to the specifications are rejected. At every phase of production, every line of filters undergoes frequent and rigorous inspection and testing to insure that our filtration products will deliver heavy-duty performance.

Integrating Total Quality Management (TQM) throughout the organization enabled us to ensure minimum variance from filter-to-filter and from order-to-order. But state of the art quality systems alone are not enough to ensure high quality filtration products. We believe high quality raw materials coupled with best-in-class manufacturing techniques determine the filtering efficiency and thus delivering top product performance.

In the field of OEM automotive filtration, knowing engine manufacturer’s quality standard specification and having the up-to-date instruments and facilities to test these standards guide our R&D and Quality Control people to continuously improve our product quality. We, as an OEM filter supplier to Japanese car makers, try to exceed car manufacturers’ requirements to ensure convenient and trouble-free use of our products.
