Alpha 95
General
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 con-
struction to the Alpha Cell HEPA filters except that
the media is 95% efficient on 0.30 micrometer par-
ticles.
Installation Considerations
Alpha 95 filters should be installed in Flanders
leak tight Alpha HEPA frames or Surelock Side
Access HEPA Housings on the positive-pressure
side of the system fan to prevent air bypass.
Sureaire diffuser sections, air mixing baffles or
long transitions should be used if the bank is close
to the fan.
Installation of Flanders ASHRAE efficiency
prefilters upstream of the fan is recommended to
ensure economical Alpha 95 filter life.

95% DOP Filter
Bulletin PB1400-1106
Standard Alpha 95 filters have 1.7 times the cfm
capacity of standard Alpha Cell 99.97% DOP HEPA
filters at the same clean pressure drop. They are
normally rated at 500 fpm so that filter banks with
95% DOP filters can be sized the same as
ASHRAE-rated filter banks.
Typical applications for Alpha 95 include:
• Hospitals
• Biomedical
• Pharmaceutical
• Biotechnology
• Genetic Research
• Universities
• Laboratories
• Food Processing
• Photo Processing
• Semiconductor Fabrication
• Industrial Processing Systems Product
