95% DOP and HEPA/ULPA Filters

Alpha 95 - 95% DOP HEPA Filter

Flanders Alpha 95 filters are designed for use in HVAC applications requiring cleaner air than is possible with ASHRAE rated filters, but where HEPA filtered air is not required. The filters are rated at 95% efficiency on 0.30 micrometer particles by the DOP test method. The Alpha 95 is rated MERV 17 per ASHRAE Standard 52.2. Alpha 95 filters are identical in design and construction to the Alpha Cell HEPA filters except that the media is 95% efficient on 0.30 micrometer particles.
