What is AIIR?
Tested and proven effective by the University of British Columbia, AIIR Classic and AIIR+ devices remove aerosols and droplets locally and synchronous to source. This collection and removal ensures that droplets and aerosols are not released into the clinical space, reducing or eliminating the risk of clinician exposure and patient cross-contamination. Furthermore, as no aerosols are released into the patient care room, the need for enclosed clinical spaces and fallow times can be eliminated or deemed a redundant infection control layer.
Why do we Care?
Procedures requiring a clinician’s long-term exposure to a patient’s breathway (ex. medical aesthetics, ambulatory care, ophthalmology), that cause a patient to cough (ex. laryngoscopy), or that mechanically generate aerosols or droplets (ex. most dental procedures, intubation, CPR, bronchoscopy), increase the risk of clinicians being exposed to respiratory illness. This increased risk is due to the fact that uncontrolled aerosols and droplets expelled by a patient, and released into the patient care room, can contain dangerous pathogens, such as Corona-Virus, HPV, Influenza, TB, Varicella, Measles, and in the case of dental procedures, aerosolised mercury.
This is not just a “COVID” problem, it is an everyday problem.
Aerosols and droplets, and the dangerous pathogens potentially within them, can remain suspended in the air column for up to 2-hours after the procedure is completed, eventually settling out and depositing on surfaces. Patients and clinicians exposed, risk infection via either airborne transmission (breathing in the suspended particle or pathogen) or contact transmission (touching a surface that a particle or pathogen has settled on, and then touching mouth, eyes etc.). Further complicating infection control measures, these suspended particles follow the air within the building and are pushed around by items like HVAC systems and people moving through the space.
In order to practice within a safe and responsible risk profile, public health authorities require that clinicians implement administrative controls and maintain universal infection control precautions to protect the public and workers alike from exposure.
Until AIIR – the only way to effectively contain and eliminate uncontrolled aerosolised particles was either to not complete the procedure, or if the procedure was necessary, to use isolation level PPE (N95, disposable gowns etc.), install fallow times (leaving the room fallow so particles can “settle out” prior to surface sterilization) and to conduct procedures in closed patient care rooms (to keep particles from spreading out of the clinical space). These solutions are not always practical or pragmatic.
Now, with AIIR, an effective, practical and pragmatic alternative exists.

Infection control protocol decisions are ultimately made by the responsible doctor or facility medical director and typically based on the guidance of Public Health Authorities. However, AIIR Classic and AIIR+ have been tested versus fallow times as an alternative administrative control by the University of British Columbia. This research shows that when used as prescribed, AIIR Classic and AIIR+ are completely effective at containing and eliminating all aerosols created (sub micron sized particles) at source and in less than 1-second. The conclusion of this research was that AIIR does not allow aerosolised particles to escape into the room, and eliminates them prior to the clinician being exposed. This makes fallow times and closed ops a redundant infection control layer.
AIIR Classic is 58 Db and AIIR Plus is 55 Db. To place this in context, both AIIR devices are at the same approximate volume as a human voice. As AIIR devices utilise premium, positive blade negative pressure generators, the sound produced is at a low frequency, and not unlike the “whooshing” sound that a white noise generator placed in a child’s room would create. For more information, please visit our downloads section for the case study titled “how loud is it?”
ACH stands for Air Changes Per Hour and when we are asked this question typically it is in the context of a doctor wanting to utilise ACH in order to reduce fallow times versus CDC or Health Canada Fallow Time tables.
ACH can be calculated by taking the room’s volume (in cubic feet) and dividing it by the amount of air passed through the specific AIIR device (cubic feet per minute). For example, AIIR Classic draws 130 CFM. A 10X10X10 operatory contains 1000 cubic feet of air. So…. 130 CFM * 60 minutes = 7800 cubic feet of air passed through the device per hour. In a room of 1000 cubic feet, this device would deliver 7800/1000 or approximately 8 air changes per hour.
Although this math is straightforward, the fundamental physics and real-life applications are not. This equation does not consider that some of the air being cleared has already passed through the device, and also, from a fluid dynamics point of view, not all air in the room is being drawn through the device.
For this reason, all AIIR devices have been modelled in the UBC computational fluid dynamics lab and tested in real-world, natural experiments. As such, AIIR devices are the most tested of their kind in the world.
No. AIIR collection domes do not interfere with the clinician’s vision and are suitable for use both with or without loupes. Please note that if you utilise an endodontic microscope that we recommend that you contact us for more information, as some endodontic microscopes are not physically compatible with AIIR.
AIIR Classic and AIIR+ were tested with the face of the dome approximately 7-10 cms from the patient’s mouth. This means that the face of the dome should be approximately the distance between the tip of a person’s pinkie to the tip of their thumb if they are holding their hand in a “hang-loose” type gesture. In this configuration, the total distance between the patient’s mouth and the stainless-steel intake orifice should not exceed 30 centimeters. This distance should allow most clinicians to complete their procedure(s) as normal, with no, or limited interference from the dome, or modular arm.
Care delivery is ultimately up to the responsible doctor, however AIIR has been proven effective at removing all aerosols and has been specifically tested as effective during use with Cavitron and three-way syringe.
Care delivery is ultimately up to the responsible doctor, however UBC research shows clearly that these methods, although effective at reducing the intensity and frequency of aerosols being released, do not eliminate all aerosols and droplets. Interestingly, experiments have shown that some droplets created and NOT captured by HVE are successfully captured by AIIR collection dome. All this being said, we recommend that while using AIIR that clinicians continue to utilise dental dams, and HVE, as a “layered” approach to infection control is the very safest approach.
Yes. The dome is a consumable item, and is replaced typically after 6-months to a year due to scratches and or fading. At less than $100 to replace however, AIIR provides for very low operating costs.
Filters are to be replaced when visibly soiled, or pro-actively every 2-months / 500 hours of use. They are $69.95. To replace, simply remove one wing-nut, remove the old filter, replace it with a new one, and then finger-tighten the wing-nut again. The procedure requires that you wear gloves, eyes protection and a surgical mask, and takes approximately 30-seconds.
The UVC lamp is rated for 8000 hours of use. A replacement bulb can be purchased for under $100 at www.carehealthmeditech.com
Yes. In both Canada and the USA, AIIR Classic and AIIR+ are considered Class I medical devices. Care Health Meditech is a Health Canada licensed (MDEL # 13004) manufacturer of Class I devices. AIIR products are imported into the United States under FDA Air Purifier and Sterilization Enforcement Policy.

It depends on the application.
AIIR Classic and AIIR+ are designed for use in the delivery of patient care (Acute, Ambulatory, Dental, Medical Aesthetics, Doctors Offices, Walk-Ins etc.) where the patient is both stationary and either supine or seated. Due to the fact that while in this configuration we know where, when and at what intensity aerosols and droplets are created, we can deliver negative pressure locally, at a focussed, and effective, but lower intensity. AIIR Sentinel is designed for use in an open environment; settings where people are moving around and or there are multiple people. AIIR Sentinel considers total room air changes (ACH) and as such has a much higher capacity and moves more air. When placed properly, or in series, and or venting to the outside, AIIR Sentinel can increase the room’s ACH. Key Point - In terms of reducing the risk of airborne infection, the larger the ACH number, the better.
Although AIIR Classic and AIIR+ can be used together, as a general rule, if you are a dentist, medical doctor, dental hygienist, or delivering medi-spa or medical aesthetics, either AIIR Classic or AIIR+ is the recommended solution.
If you are placing a device to improve air circulation and purification indoors in buildings such as churches, indoor meeting areas, retail stores, restaurants, staff rooms, indoor places where people are moving around and the space is open, AIIR sentinel is the recommended choice.
AIIR Classic arm can be retrofit with the AIIR+ arm, as the connection point is identical. This allows for the benefit of improved arm mechanics and ergonomics, however delivers a drawback of increased device total weight as the counterbalance mass of AIIR+ is contained within the arm itself. AIIR+ arms are available for retrofit at an investment of $399 plus shipping and require no tools or special training for retrofit. Retrofit takes approximately 30-seconds.
All AIIR devices come standard with a limited lifetime warranty. This means that the device itself is warranted against defect in workmanship for as long as you own it. This warranty is only available to the original purchaser and is not transferable. Exclusions to the warranty are as follows.
a) Seals and gaskets are excluded, and carry a warranty of 1-year
b) Consumables (UVC Lamp, Dome and Filter) are excluded
c) Negative Pressure Generator is excluded, however has its own warranty of 5-years
