Understanding Alarms
Low Battery Alarm
The Low Battery Alarm will
sound an electronic beep
indicating that there is
approximately 5% charge
remaining.
Low Airflow Alarm
The Low Airflow Alarm will
sound a continuous
electronic beep indicating
that the flow to the hood
has dropped below the
designed specifications of
170 L/min (6 CFM)
Loss of Communication
The Loss of
Communication will sound
a continuous electronic
beep of varying
frequencies indicating that
the blower motor and
battery are no longer
communicating.
Changing the HEPA filter
If the SALUS respirator is being used to reduce exposure to airborne biological aerosols
such as droplets containing viruses or bacteria, the HEPA filter will likely not load (clog)
from these particles to the point that they will affect airflow. Loading of the HEPA filters
is typically not an issue when used for biological aerosols.
In healthcare facilities, PAPR filter change schedules for airborne biological aerosols
are primarily determined by the facility’s infection control policy, which should be
developed based on applicable national, state, and local guidelines. Most healthcare
systems develop their filter use and reuse policy based on the biological agent of
concern, likelihood of the filter becoming contaminated, and potential for patient-to-
patient and patient-to-worker cross-contamination.
While the outside filter body can be wiped down for cleaning, do not attempt to clean the
filter media inside the filter body. When changing the HEPA filter, follow the hygiene and
infection control practices established by your employer based on the specific
contaminants to which the respirator assembly has been exposed and the cleaning
agent used.
Selecting Hood Size
The LF-Series hood is available in
two (2) widths and three (3) sizes in each width to
accommodate various
face and head sizes for maximum comfort and protection.
The comfort-fit, designated by 20LF, has a wider profile while the contour-fit, designated
by 20LF2, has a narrower profile.
If using the LF-Series hood, select the size that fits most comfortably and where the
entire elasticized edge of the faceseal encounters your face. For additional guidance,
refer to the LF-Series Sizing Chart to further match your face shape and head size. If
your proper fit falls between two (2) sizes, default to the smaller size to ensure a snug
fit.
