The SynthaMax filter media consists of an inner and outer layer of wire mesh for durable support of
filtration media as well as overall filter durability. This filter construction
will not deform or collapse under high air flow. The inner filter media
consists of two distinct layers of specifically designed synthetic materials
that have separate performance characteristics designed to work together for a
combined function of outstanding air flow (low restriction) and exceptionally
high filtration. Contaminants are first captured by the outer layer of
synthetic needlefelt polyester material designed for wet and dry filtration with
high air flow capacity. The inner layer of (wet-laid / chemical bonded) (rayon
/ polyester) captures any remaining contaminants while maintaining high air flow
and low restriction. Each separate layer of these high tech materials are
design to work together for the highest level of air flow performance and
filtration with exceptional durability.
