The CerroZone Mini is intended as a room recirculating air cleaner. The system is used for filtering out and inactivating airborne particles (i.e., bacteria and viruses) from the air for medical purposes.

The CerroZone Mini is a medical recirculating air cleaner that uses multiple inactivation processes, including use of reactive oxidizing species (ozone) and ultraviolet radiation, to inactivate bacteria and viruses in the CerroZone Mini may be used in medical facilities. Once turned on, inlet air is passed through CerroZone Mini's inline flow-through design which inactivates bacteria and viruses in a single pass flow-through. The device generates 110 cubic feet of air per minute (CFM), or 2.00 air changes per hour (ACH) in a standard 5,600 cubic foot room. The process of air being inlet, purified, then outlet, lasts approximately 1.2 seconds. A 4 LOG reduction, or 99.99% reduction, of airborne particles in a standard 579 cubic foot room is achieved in 45 minutes or less.

The prompt requests information about a study proving that a medical device meets acceptance criteria. The provided text is an FDA 510(k) clearance letter for the CerroZone Mini, a medical recirculating air cleaner. The document details the device, its indications for use, comparison to a predicate device, and summarizes non-clinical testing.

However, the provided text does not contain the specifics of a study proving device acceptance criteria in the way one might expect for an AI/algorithm-driven medical device, which is what the prompt implies by asking about sample sizes for test and training sets, expert ground truth, adjudication methods, and MRMC studies. The device in question is an air cleaner, and the "studies" mentioned are laboratory tests assessing its ability to reduce airborne biological agents and ozone emissions, not clinical trials or AI performance evaluations involving human-in-the-loop scenarios.

Therefore, many of the requested points are not applicable to the data provided for this specific device. I will address only the points for which information is available in the text.

Here's the analysis based on the provided document:

1. A table of acceptance criteria and the reported device performance

2. Sample sizes used for the test set and the data provenance

The document does not specify exact "sample sizes" in terms of number of runs or specific data points for the biological agent reduction tests, nor does it explicitly state the precise "data provenance" (e.g., country of origin, retrospective/prospective). These are laboratory efficacy and safety tests, not clinical studies with human subjects or large datasets typical for AI model validation. The tests were performed in a controlled laboratory environment.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable. "Ground truth" in the context of this device's testing refers to measured physical/biological parameters (e.g., log reduction of bacteria/viruses, ozone concentration), not expert interpretation of medical images or other data typically associated with AI/diagnostic devices. The results are based on quantitative laboratory measurements.

4. Adjudication method for the test set

Not applicable. There was no need for adjudication as the "ground truth" was established through direct laboratory measurements, not subjective evaluations or consensus processes.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This device is an air cleaner, not an AI-assisted diagnostic or decision support tool for human readers. No MRMC study was performed.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable beyond the device's inherent standalone function as an air cleaner. There is no AI algorithm in the traditional sense that performs a diagnostic or interpretive function. The device's performance is its inherent physical and chemical action on airborne particles.

7. The type of ground truth used

The ground truth for the biological agent reduction tests was established through direct quantitative laboratory measurements of the reduction in viable MS2 bacteriophage and Staphylococcus epidermidis concentrations. For ozone emissions, the ground truth was direct measurement of ozone concentration in ppm. For electrical compatibility and safety, the ground truth was compliance with specified international and national standards (EN/IEC 60601-1-2, UL 867, CSA C22.2 No.187), verified through standard engineering tests.

8. The sample size for the training set

Not applicable. This device is an air cleaner with a physical mechanism of action, not a machine learning model that requires a "training set."

9. How the ground truth for the training set was established

Not applicable as there is no training set for this device.

This document pertains to an air purifier, and its "performance data" is focused on physical and biological filtration capabilities, not on an AI's diagnostic or assistive accuracy.

Therefore, I cannot extract information related to:

• Sample size used for the test set and data provenance (e.g., country of origin, retrospective/prospective)
• Number of experts used to establish ground truth and their qualifications
• Adjudication method for the test set
• Multi-Reader Multi-Case (MRMC) comparative effectiveness study or effect size
• Standalone (algorithm only) performance
• Type of ground truth used (expert consensus, pathology, outcomes data)
• Sample size for the training set
• How ground truth for the training set was established

However, based on the provided text, I can infer the "acceptance criteria" and "reported device performance" related to the air purifier's function.

Here's a breakdown of what can be extracted:

1. A table of acceptance criteria and the reported device performance

While not explicitly called "acceptance criteria" with pass/fail thresholds in the typical AI/ML sense, the document lists specifications and test results that serve as performance benchmarks.

Not Found

This document is a 510(k) premarket notification from the FDA, indicating that the device being reviewed is a Medical Recirculating Air Cleaner. Therefore, the device in question is not an AI/ML powered device. The information requested in your prompt (e.g., acceptance criteria for AI algorithms, sample sizes for AI model training/testing, expert adjudication, MRMC studies) is typically associated with the evaluation of AI/ML-driven medical devices.

Since the document provided is for a physical air cleaner and not an AI/ML device, most of the requested information does not apply. However, I can extract what is provided in the document related to acceptance criteria and performance of this physical medical device.

Here's an analysis based on the provided document:

The acceptance criteria for the MA-40 and MA-112 air cleaners are based on their ability to reduce airborne microorganisms. The study proves that the devices meet these criteria by demonstrating a reduction of specific bioaerosol types by >99.99% within certain timeframes in a test chamber.

1. A table of acceptance criteria and the reported device performance

The acceptance criterion for both devices is to reduce airborne microorganisms by >99.99%. The tables provided show the time taken to achieve this reduction for different bioaerosol types and device fan speeds. The device performance (achieving >99.99% reduction) is reported for each scenario.

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

• Sample Size: The test "sample" here refers to the conditions under which the device was tested. The performance was demonstrated "in a test chamber of 83ft³ (580 ft³)". It's not a biological sample size in the sense of patient data. The document does not specify the number of individual tests or replicates run for each bioaerosol type and fan speed.
• Data Provenance: The document does not specify the country of origin of the data or whether the study was retrospective or prospective. It is a report of performance in a controlled test chamber.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This question is not applicable as this is a physical device being tested for its ability to filter and inactivate microorganisms, not an AI/ML algorithm requiring expert interpretation of medical images or data. The "ground truth" is measured by the reduction of bioaerosols in a controlled environment.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable. This is not an adjudication process for human interpretation or AI output. The performance is based on quantitative measurements in a laboratory setting.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This is not an AI-powered device, and therefore no MRMC study involving human readers and AI assistance would be conducted.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable, as this is not an AI/ML algorithm. The "standalone" performance is the device's ability to purify air without human intervention beyond turning it on and setting the fan speed.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

The "ground truth" is the measured reduction of specific bioaerosol concentrations within the test chamber. This is determined through laboratory methods suitable for quantifying microorganisms, which is an objective measurement rather than a subjective expert assessment.

8. The sample size for the training set

Not applicable. This is a physical device, not an AI model that requires a training set.

9. How the ground truth for the training set was established

Not applicable. There is no training set for this type of device.

The provided text describes the mechanical and electrical performance of an air purification device, not an AI/ML-enabled medical device. Therefore, the information typically required for an AI/ML device's acceptance criteria, such as details about ground truth, expert adjudication, MRMC studies, or training set data, is not present in this document.

However, I can extract the acceptance criteria and study details relevant to this specific device based on the provided text.

Here's a breakdown of the acceptance criteria and the study that proves the device meets them, according to the document:

1. A table of acceptance criteria and the reported device performance:

2. Sample sized used for the test set and the data provenance:

• Sample Size: The document does not specify a "sample size" in the context of a test set for an AI/ML model. Instead, it refers to a single device (RIA SafeGuard, Model Number: SG020MS120) that underwent non-clinical testing.
• Data Provenance: The tests were conducted on the subject device, RIA SafeGuard. The exact location or origin of the testing data is not explicitly stated, but the manufacturer is RIA Tech Co., Ltd. located in Taipei City, Taiwan (R.O.C.). The tests were "non-clinical," implying they were conducted in a laboratory or controlled environment, rather than involving patient data (retrospective or prospective).

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

This information is not applicable to this device's testing. "Ground truth" in the context of an AI/ML model usually refers to labeled data verified by human experts. For a physical device like an air cleaner, the "ground truth" is established through direct physical measurements against predefined engineering and safety standards (e.g., measuring particle reduction with sensors, ozone concentration with detectors). No human experts were involved in establishing the "ground truth" for these physical performance metrics.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

This information is not applicable. Adjudication methods are relevant for subjective interpretations of data, typically in AI/ML model validation where multiple experts might disagree on labels. For the physical performance tests conducted, the results are objective measurements that do not require adjudication.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

This information is not applicable. An MRMC study is relevant for evaluating the impact of an AI/ML system on human performance (e.g., how radiologists improve diagnostic accuracy with AI assistance).

The CerroZone Mobile is intended as a room recirculating air cleaner. The system is used for filtering out and inactivating airborne particles (i.e., bacteria and viruses) from the air for medical purposes.

The CerroZone Mobile is a medical recirculating air cleaner that uses multiple inactivation processes consisting of reactive oxidizing species (ozone) and ultraviolet radiation to inactivate bacteria and viruses in the air. The CerroZone Mobile may be used in medical facilities. Once turned on, inlet air is passed through CerroZone Mobile's inline flow-through design which inactivates bacteria and viruses in a single pass flow-through. The device generates 220 cubic feet of air per minute (CFM), or 2.36 air changes per hour (ACH) in a standard 5,600 cu. Ft room. This process of air being inlet, purified, then outlet, lasts approximately 1.2 seconds. A 4 LOG reduction of airborne particles in a standard 579 cu. Ft room is achieved in 30 minutes or less. A 5.67 LOG, or 99.9998%, reduction is achieved in 45 minutes or less.

The CerroZone Mobile device is a medical recirculating air cleaner designed to filter out and inactivate airborne bacteria and viruses. The following information summarizes its acceptance criteria and the studies conducted.

1. Table of Acceptance Criteria and Reported Device Performance:

2. Sample Size Used for the Test Set and Data Provenance:

The document does not explicitly state the sample sizes for the biological aerosolization tests (MS2 bacteriophage and MRSE). The studies appear to be laboratory-based non-clinical tests rather than human subject or field trials, so terms like "country of origin" and "retrospective/prospective" might not be strictly applicable in the same way they would be for clinical studies. The context implies these were controlled experiments conducted to assess device performance under specific conditions.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:

This information is not provided in the document. The "ground truth" for these non-clinical tests would have been established by the direct measurement of reduction in viable microorganisms using standard microbiological techniques, rather than expert interpretation.

4. Adjudication Method for the Test Set:

Not applicable. The tests involved direct measurement of microbial reduction, not subjective interpretation requiring adjudication.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done:

No, an MRMC comparative effectiveness study was not done. The CerroZone Mobile is a medical device for air cleaning, not an interpretative diagnostic tool, so such a study would not be relevant.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done:

These were standalone performance tests of the device itself (algorithm not applicable), evaluating its ability to reduce airborne pathogens directly.

7. The Type of Ground Truth Used:

The ground truth used for the efficacy studies was based on quantitative laboratory measurements of microbial viability (e.g., plaque assays for bacteriophages, colony counts for bacteria) before and after exposure to the device. For ozone emissions, the ground truth was direct quantitative measurement of ozone concentration.

8. The Sample Size for the Training Set:

Not applicable. This device is a physical air cleaner, not an AI/ML algorithm. Therefore, there is no "training set" in the context of machine learning.

9. How the Ground Truth for the Training Set Was Established:

Not applicable, as there is no training set for this type of device.

The Airsonett AIR-4 is a Mobile Air Cleaner intended to be used to remove particles from the air for medical purposes. The device is intended for home use only.

Airsonett is based on the Temperature controlled Laminar Airflow (TLA) technology. The air from the room enters the Airsonett and passes a filter that captures allergens and other particles. The filtered air is cooled to slightly below the ambient room temperature and is supplied with a low velocity from the air supply nozzle. Since the filtered air is slightly cooler, and therefore heavier than the surrounding air, the filtered air will descend slowly from the air supply nozzle by means of gravity in a laminar manner (non-turbulent). This descending colder air counteracts the body convection, displaces the allergen load in the breathing zone and thus dramatically reduces the level of inhalant allergens for the patient all through the night.

Air is drawn in through the air intake at the floor level and through the HEPA filter. A silent Blower (fan) brings airflow through the filter. The air is directed through the Cooler/Heater and divided into a cool respectively warm air flow. The cool air flow is directed through the Air guidance arm (neck) and out through the Airshower (Air Supply Nozzle). The Airshower can be altered in height, by adding/removing and combining the neck parts, to adapt to different types of environments. The warm air flow is directed to the Warm air outlet. On its way to the outlet the air flow passes the electronics and transports away the extra heat produced by the electronics.

Airsonett is based on a microprocessor controlled supervisory system. This system controls the device behaviour by measuring temperatures, controlling thermoelectric modules and fan unit, monitoring user interaction as well as management of internal timers to keep track of the total ontime for the system and time since last filter change. The control functions (Front Panel Board) and power distribution function (Power Electronics Board) are allocated on two separate circuit boards.
