Advantage — Handling-friendly

Traditional fiberglass media is quite fragile and easily tear off.  Filter manufacturers have to hire experienced workers to assemble filters with special care, and end users have to hire trained workers to do filter installation.  With a protection layer, KOPU media and filters of KOPU media are no longer fragile.  This may take off half of customer’s headaches in dealing with fiberglass.

Advantage — Formaldehyde-free

Our competitors use formaldehyde based binders in fiberglass media.  Such glues may have a danger in outgassing formaldehyde.  Binders used by 4Ge contains and outgas hardly any formaldehyde.

Advantage — Long service-life

A carefully chosen top layer serves as a pre-filter layer to protect fiberglass.  Pocket filters made of COPU may give a longer service-life compared with the traditional fiberglass, depending on filter designs and applications.
