    HEPA Box Air Filters

    Provide exceptional filtration in hospitals, clean rooms, and other places where you need to control airborne contaminants. The rigid frame withstands withstands fluctuations in airflow, such as those created by variable air volume systems. There's a sealing gasket on the downstream side of the filter to prevent leaks.
    For a more affordable alternative to HEPA filters, consider ultra-efficiency filters. They are made for areas where absolute filtration isn't required.

    ULPA Box Air Filters

    Image of Product. Front orientation. Air Filters. ULPA Box Air Filters.
    Purify the air in your most sensitive environments. Since ULPA filters remove 99.999% of particles, they're used in semiconductor, pharmaceutical, and aerospace facilities. Constructed with fibers more densely woven than HEPA filters, they catch 10 times more particles. However, they need to be changed more often because they collect contaminants more quickly.
