Air Cleaners, High-Efficiency Filter Scope of this Product Comparison
This Product Comparison covers high-efficiency-filter air cleaners used in general-use and high-risk
areas of healthcare facilities. Units that discharge into the general ventilation system for recirculation or
that solely provide room-air exhaust to the outdoors to create negative pressure are excluded.
These devices are also called: mobile air filters, medical recirculating air cleaners, negative-pressure
air filtration systems, high-efficiency particlate air (HEPA) filtration units.
Purpose
High-efficiency-filter air cleaners (HEFACs) are
used to reduce the local area concentration of
airborne infectious Mycobacterium tuberculosis (TB)
droplet nuclei. Since 1985, the number of people
infected with TB has increased significantly,
particularly in healthcare facilities, homeless
shelters, and correctional institutions. Long-term
drug treatment is sometimes successful; however,
multidrug-resistant strains of TB (MDR-TB) have
been reported in healthcare facilities, affecting both
patients and personnel. Further complicating the
spread of TB in healthcare facilities is the increased number of patients with human immunodeficiency
virus (HIV). Patients with HIV are more likely than others to contract TB, and certain treatment
procedures, such as those that induce coughing, can increase the likelihood of nosocomial airborne
transmission of TB via infectious droplet nuclei.
One method of dealing with this problem is to institute adequate infection-control programs in
healthcare facilities, including the use of engineering controls.
TB is usually transmitted when an infected patient coughs,
sneezes, or otherwise releases infectious particles into the air.
Infection can occur when another person inhales the particles
before they settle or are otherwise removed from the air. After
release, droplets that are not immediately inhaled begin their
descent and desicate rapidly. Larger droplets fall to the ground
or onto another surface before evaporating; other droplets
evaporate into nuclei of 1 to 5 µm in diameter. These droplet
nuclei settle extremely slowly and can remain airborne on normal
air currents generated in an occupied space until they are
removed by some means of ventilation.

Principles of operation
HEFACs generally contain one or more of the following components:
An intake duct
A HEPA filter or some higher-efficiency filter, such as a super-HEPA or ultra-low-
penetration air (ULPA) filter
A prefilter, such as a polyester fiber filter, used to increase the life of the more costly HEPA
filter by removing large particles before they reach the HEPA filter
A motor/blower assembly
An exhaust duct
A control panel containing an on/off switch, an airflow speed control, and possibly a
differential pressure gauge (which usually indicates the pressure drop across the HEPA
filter. This pressure drop can be used as a relative measure to determine whether the filter is
dirty and in need of replacement) and/or a filter-change indicator (e.g., hour meter, timed
warning light)
Essentially, a HEPA filtration system pulls room air into the unit and through the filter to remove
particles, then exhausts the filtered air back into the room (or to another designated location) at a selected
flow rate.
The airflow pattern created by the unit varies with the location of the intake and exhaust and the flow
velocity. These systems often use either an “upflow” pattern, with the intake near the bottom of the unit
and the exhaust near the top, or a “downflow” pattern, which is the reverse. Several systems contain the
option for integrated ultraviolet germicidal irradiation (UVGI) lamps and an additional charcoal filter to
remove odors. Depending on the unit’s design, UVGI lamps are placed either upstream or downstream of
the HEPA filter.
Most systems have more than one configuration, allowing them to provide a number of functions,
such as the following:
Exhaust of filtered air (either directly to the outdoors or back into the general ventilation
system)
Recirculation of air, which has been filtered to remove infectious particles, into the room or
to other areas of the facility (either through existing or prefabricated ducts or directly from
the unit’s exhaust duct)
A combination of both exhaust and recirculation (the exhaust option can provide negative
room pressure, while the recirculation option is intended to remove airborne particles and
increase the number of room air changes through HEPA-filtered air)
Depending on the configuration, the system may be wall mounted, ceiling mounted, floor mounted, or
freestanding on a mobile base.
The extent to which a room is cleared of infectious particles varies significantly with the volume of the
room and the airflow of the HEFAC. For a TB isolation room, the Centers for Disease Control and
Prevention (CDC) recommends the following:
≥12 air changes per hour (ACH); ≥6 ACH for existing rooms
Air directly exhausted to the outside
Negative pressure in relation to the surroundings
The following formula can be used to determine the best air cleaner for a designated room based on
the room’s volume (expressed in cubic feet) and the manufacturer’s listed airflow rate (expressed in cubic
feet per minute):
ACH × (room volume) ÷ 60 = cfm

For example, using the CDC’s recommended 12 ACH, a 10’ x 10’ x 12’ room (1,200 ft3) will need an air
cleaner with an airflow rate of at least 240 cfm. A 20’ x 30’ x 15’ room (9,000 ft3) will need an air cleaner
with an airflow rate of at least 1,800 cfm.
Some HEFACs have UVGI lamps as an additional method of air cleaning. Although it is controversial
and is recommended by CDC as a supplemental method only, UVGI is used (1) in ventilation ducts and
in-room units in a manner similar to the use of HEPA filters or (2) in lamp fixtures for upper-room air
irradiation.
Reported problems
Few operational problems have been reported regarding HEFACs; most concerns about the units are
related to usage. One such concern is the placement of the unit in the room. CDC and ECRI Institute
caution that the air-cleaning efficacy of these units may vary with room configuration and placement
within the room relative to ducts and furniture. The airflow patterns created by poorly placed units may
be more hazardous, pushing contaminated air toward doors leading to corridors or short-circuiting
airflow, filtering already disinfected air, and leaving rooms with dead spaces that still contain
contaminated air.
Proper airflow and negative pressure in a room are crucial factors in maintaining the cleanest air
possible. Open doors to corridors and bathrooms, open windows, and bathroom exhaust fans can all
affect the airflow and negative pressure of a room. When the airflow patterns are altered, the risk of
transmitting infectious particles can increase.
The noise levels of HEFACs can also present problems. Higher noise levels are associated with a
higher rate of air flow. Many units can operate below conversation noise levels, but noisy units can
disturb patients and healthcare workers or mask audible alarms.
HEFACs with UVGI lamps could expose maintenance personnel to ultraviolet (UV) radiation, which
causes tissue injury. Some units have a special UV-shielding filter to prevent eye- and skin-damaging
energy from escaping from the unit. Also, some UVGI lamps generate ozone when new; this can be an
irritant. UVGI can also damage plastics.
Purchase considerations
ECRI Institute recommendations
Included in the accompanying comparison chart are ECRI Institute’s recommendations for minimum
performance requirements for HEFACs.
The efficacy of any unit will depend on its airflow rate in relation to the size and layout of the room.
ECRI Institute recommends that facilities attempt to maintain an ACH of at least 12. However, purchasers
should be aware that manufacturer-stated airflows are not always accurate; ECRI Institute advises
facilities to work with ventilation consultants, clean-room certifiers, or industrial hygienists when
addressing issues of TB infection control to optimize the performance of HEFACs.
ECRI Institute recommends that the unit’s fan be situated downstream from the HEPA filter. A
downstream location is preferred to keep the fan as clean as possible.
The unit should be equipped with a filter-change indicator. Some units have LED indicators, while
others may rely on a pressure gauge. Pressure gauges are recommended for their use in monitoring
system performance in general; measuring changes in pressure can help indicate that the filter is dirty or
that there are leaks in the seal of the HEPA filter. The life of the HEPA filter can be prolonged by the use
of a prefilter, which ECRI Institute recommends as a required feature in any HEFAC unit.

Though many HEFACs offer the option of a UVGI lamp, ECRI Institute does not recommend them.
Because HEPA filtration is effective in removing TB droplet nuclei and most other organisms, UVGI as a
component of HEFACs is an unnecessary added expense and potential health hazard due to their
harmful effects on exposed skin and eyes and their creation of ozone.
HEFACs should be easy to set up and should require minimal training, so basic personnel can operate
and maintain them. The following features are recommended for ease of use:
Easily read and understood dials and gauges
Ability to be easily cleaned
Ability to be easily moved
Easily performed filter removal, replacement methods, and other required filter
maintenance
Easily understood instructions for routine maintenance and service
Other considerations
All HEPA filtration units require ongoing maintenance to ensure safe and effective operation. Both
HEPA filters and prefilters must be changed periodically (HEPA filters, every one to two years; prefilters,
generally every 60 to 90 days, depending on conditions), and routine inspections must be performed to
check for adequate airflow and possible leaks around the filters or in the housing. The more frequently
the filters must be changed, the more expensive the ongoing costs and the greater the risk to personnel
performing such maintenance. However, if filters are not changed often enough, decreasing airflow will
lessen the capture and filtration efficiency, increasing the risk of TB or other airborne disease
transmission.
To combat the resurgence of TB, hospitals must meet prevention requirements that can be costly to
implement. For example, an existing isolation room must normally have 6 ACH and be under negative
pressure. Achieving the CDC recommendation of ≥12 ACH to reduce the room’s concentration of TB
droplet nuclei may require extensive and costly renovations to the ventilation system. By providing ≥12
ACH, a HEFAC is an inexpensive means of upgrading the isolation room or of converting an existing
area to a TB isolation room.
When comparing the costs of various alternatives, buyers should include initial acquisition,
installation, and operating costs. A HEFAC can have an initial cost of up to $9,000; consumables and
electric usage double the total cost over five years. The following list describes associated consumable
costs:
Prefilters, which are changed approximately every 60 days, depending on the amount of dirt
in the air, typically cost about $25 each. Units that pull air from the floor may require the
prefilters to be changed more frequently because of the dust and dirt settling in or tracked
into the room.
HEPA filters, which are typically changed every one to two years, depending on the quality
of the air and the amount of time in use, are more expensive, at about $200 to $400 each.
(Prefilters upstream of the HEPA filter can extend the life of the HEPA filter by up to 25%.)
For units that use UVGI, the UVGI lamps, which typically must be replaced yearly, can cost
up to $90 each.
Most HEFACs use about 3 A at 120 V and must be run continuously when a patient is
occupying the room; this costs about $320 per year per unit, depending on the cost of
electricity.
Overall, HEFACs used in conjunction with other appropriate engineering controls and personal

protective equipment (e.g., masks), as recommended by CDC, offer a cost-effective method of controlling
the transmission of TB.
Stage of development
As TB control procedures and regulations become more clearly defined, the effect of air filters on the
control of TB transmission will become more apparent. HEFACs are considered a useful supplementary
control in the prevention of spreading infectious particles; however, just how effective HEFACs are
remains unclear. As the units are used more frequently and more data regarding their efficacy is
available, they can be modified to be safer and more efficient and to help control the spread of TB in
healthcare facilities more effectively.
As an alternative to manual monitoring of pressure, some facilities are installing automated systems
that log pressure changes and sound an alarm when levels rise above or dip below acceptable levels and
permit contaminants to drift in the wrong direction.
