Disposable Panel Filter, Coarse Filter as First Stage Air Inlet Filter

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 and secondary filters, we buy the filter media of optimum quality from Chinese native market. Their quality is stable and super. As for the HEPA filters, the glassfiber media is 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. Welcome to have a Virtual tour to our factory by clicking the following:https://thenow-filter.en.made-in-china.com/ Product DescriptionDisposable panel filter,coarse filter as first stage air inlet filter>StructureFrameFilter MediaFace netWater resistant cardboardPolyester/PolycottonSpot mesh, expanded mesh  >Feature:Self-supporting materialNo metal, thus fully incinerableLow pressure drop media   >Technical data:1.
