Product Description
Foreword:
Thank you for your interest in advance!
It has been 16+ years since we processed the first HVAC air filter.
You can find various replaceable filters for Camfil, AAF etc. We have all kinds of frames and filter media available. As for prefilter media and secondary filters, we buy the optimum quality from Chinese native market. Their quality is stable and super. As for the HEPA filters, we imported from American Lydall and Suzhou H&V. We control the quality from the source.
There are plenty of testing machines in our laboratory including filter media testing and completed filters tested.
