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 filter
is approximately 99% efficient by the ASHRAE 52.1
dust spot test methods. However, it is not rated by
these methods because the standard applies to
filters no greater than 98% efficient.
Alpha 95 Filters are 97% efficient on nebulized
staphlococcus aerosols and are used to remove
biological contaminants. 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. Typical applications
for Alpha 95 Filters include:
