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.
