Primary/Secondary filters

OmniAire HEPA negative air machines are shipped with a dual-ply Dustlok polyester pad media primary/secondary filter. Frequent replacement of these filters will greatly enhance the useful life of the HEPA filter.

Some of the key features of these filters are

    MERV 8 Efficiency

    Dual-Density for Progressive Depth Loading and Long Life

    Effective Control of Mold, Mildew, Algae, Fungi on the Filter

    Flame Retardant – UL Class 2 Rating

Dustlok adhesive uniquely coats the fibers in the downstream layer and absorbs dust particles, trapping them on the individual fibers. The adhesive does not dry out or migrate.

Distinct Dual Density provides high dust holding – long service life. The air enters the coarse, open structure of the white media which captures the large particles. The orange, dense, downstream layer effectively stops and traps the finer particles.

SPOR-AX Antimicrobial is a biocide that effectively controls growth of mold, mildew, algae and fungi on filter. SPOR-AX will not off-gas, migrate or leach into the air stream.

Replacement primary/secondary filters are cut-to-size for OmniAire HEPA negative air machines and packed in boxes of 20. If the filter does not have Dustlok stamped on it, it is not a Dustlok filter.
