Does recirculating air in waiting rooms or any room, help?
The
use of recirculation of purified air in any type of room or specifically
a waiting room would even offer increased protection to you at home
or to the health care worker and patients, in a medical facility.
The basic air change of 6 ACH in rooms and 12 ACH in hospitals as
well as the mixing factors used for these larger areas is typically
border-line when dealing with areas that have more occupants than
the standard rooms.
Increasing the air changes also dilutes the airborne pathogens in
the air thus reducing exposure and exposure times for the occupants.
Also, the increase in air changes increases the mixing factor so that
the existing HVAC system can work more effectively.
One can purify air to the Nth degree but if the air is not circulated
to all areas of the room then the process is worthless.
The NQ unit has both UV lights and HEPA filters so that you can be
quite confident of the cleanliness of the air that you are circulating.
Building codes do allow you to add this air flow amount to the total
ACH.
In our experience, the use of a supplemental air handler for air dilution
is an industry and a CDC recommended way to reduce spread of any airborne
disease. The energy use of the fan and lamps are minimal if compared
to the use of outdoor air for the dilution effect talked about above.
Lamps do last about one to two years and the required kill rate for
TB is one third (1/3) of what the lamps put out, even after 2 years
of use.
We have had many hospitals use these units to supplement their air
changes in waiting rooms.
