The XJ-2 HEPA Air Cleaner for Filtration in Hospitals, AIIRs & Healthcare Settings

XJ2 Hepa air cleaner

The Centers for Disease Control (CDC) has published “Interim Infection Prevention and Control Recommendations for Healthcare Personnel During the Coronavirus Disease 2019 (COVID-19) Pandemic.”

This online document can be accessed at https://www.cdc.gov/coronavirus/2019-ncov/hcp/infection-control-recommendations.html and reads as follows:

“Airborne Infection Isolation Rooms (AIIRs) should be prioritized for patients who will be undergoing aerosol generating procedures (See Aerosol Generating Procedures Section).”

The hospital grade XJ-2 unit quickly and easily converts ordinary patient care rooms into negative pressure isolation rooms or airborne infection isolation rooms. The XJ-2 is HEPA-filtered and available from Air Quality Engineering. This air filtration system complies with the above guidance from the CDC.

Call Air Quality Engineering at 1-888-883-3273 for pricing and shipping information.

For air purification, the XJ-2 is a quiet medical-grade room HEPA air cleaner that is suitable for airborne infection isolation rooms (AIIR), hospitals, medical facilities, extended-care facilities, nursing homes and institutional use. This portable unit is also a great unit for asthma patient rooms. The XJ-2 air filtration system is independently lab tested and certified as a whole air cleaner to a minimum of 99.97% efficiency. This is especially important as simply installing a HEPA air filter into an air cleaner cabinet can not guarantee HEPA performance as penetrations into the air cleaner cabinet, leaks around doors and the integrity of the HEPA seal itself must all be taken into consideration and tested to guarantee performance. Replacement filters and parts for the XJ-2 are also available. Make sure to ask whether the air cleaner was HEPA tested as a whole before purchasing!

The XJ-2 Negative Pressure HEPA unit provides isolation capability in urgent circumstances. This highly portable self-contained model is designed to minimize floor space utilization, be adaptable to other enhanced air filtration needs with the optional recirculation plenum and can be utilized in special positive pressure applications. The adaptable XJ-2, is a rugged functional workhorse, providing the essential airflow and pressure differential needed for tough duty. The XJ-2 with its HEPA filtration, most commonly recommended by health authorities, is an excellent candidate for healthcare, office, and school applications.

Looking for more information on AIIRs? ASHRAE standard 170-2017 goes into detail about ventilation in healthcare facilities. This online document can be accessed at techstreet.com and includes the following:

“Information about Airborne Infection Isolation Rooms (AIIRs):

  • AIIRs are single-patient rooms at negative pressure relative to the surrounding areas, and with a minimum of 6 air changes per hour (12 air changes per hour are recommended for new construction or renovation).
  • Air from these rooms should be exhausted directly to the outside or be filtered through a high-efficiency particulate air (HEPA) filter directly before recirculation.
  • Room doors should be kept closed except when entering or leaving the room, and entry and exit should be minimized.
  • Facilities should monitor and document the proper negative-pressure function of these rooms.”

XJ-2 HEPA filtration unit and filters

Unlike some units where just the filter is tested to HEPA efficiency, the XJ-2 was independently lab tested in its entirety to be 99.999% efficient on 0.3 micron particles.

The XJ-2’s Quiet operation design features include a backward curved, dynamically balanced impeller and a sound dampening blower baffle to reduce sound levels to a minimum.

The XJ-2’s certified HEPA air filter is highly effective in removing microorganism-sized particulate. The 80-85% efficient prefilter protects the HEPA filter reducing maintenance costs. Provides 12 air changes per hour, enough for most hospital rooms.

The XJ-2 is shipped fully assembled and ready for roll in installation.
