Isolation Room XJ-2 Air Filtration System

We provide industrial electrostatic air cleaner services to the greater Chicago, Indiana, Michigan and Wisconsin area. Reach out by phone or email to speak with one of our team members.


The XJ-2 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.

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 Centers for Disease Control (CDC) has published “Interim Infection Prevention and Control Recommendations for Patients with Suspected or Confirmed Coronavirus Disease 2019 (COVID-19) in Healthcare Settings.”

This on-line document can be accessed at and reads as follows:

Protect healthcare personnel. Emphasize hand hygiene, install barriers to limit contact with patients at triage, cohort COVID-19 patients, limit the numbers of staff providing their care, prioritize respirators, and AIIRs for aerosol-generating procedures, implement PPE optimization strategies to extend supplies.”

Looking for more information on AIIRs? ASHRAE standard 170-2017 goes into detail about ventilation in healthcare facilities. This on-line document can be accessed at 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.”
