INTRODUCTION

The Honeywell Air Detective is intended for use by HVAC and environmental test professionals to analyze residential air quality for selected allergens including spores, specific pollen types, as well as other organic particles. The Honeywell Air Detective system consists of three elements:

1.  The device and its associated hardware collect the air samples and provide the particle holographic imagery to the cloud database for analysis.
2. The cloud-based, machine-learning software which analyzes the detected particles and provides results report in near-real-time.
3. The user-supplied iPad tablet controls the device application and the interface to the cloud and also displays the results report.

The device uses a fan to in-take and capture an air sample through the impaction sampler built into a single-use, disposable cassette. After sampling the air for three minutes, the device records holographic images of the particles detected in the air sample. These images are then sent to the cloud for on-the-spot, near-real-time particle classification and
display.

The results are returned to the iPad, providing an analysis report o share with the homeowner in person and via e-mail. This  data is intended to help HVAC professionals and
homeowners make informed decisions about the types of air handling, cleaning equipment, and services that may be beneficial to the homeowner.

 HONEYWELL AIR DETECTIVE REPORT

The detailed Honeywell Air Detective Report provides particle concentrations, images, and categories, as well as size data. It also provides important information and helpful links to aid in interpreting the results. Figure 6. A shows excerpts are taken from a particle report that sampled the air in an indoor location, in this case, an office. See also Tables 6. A and 6. B for more information.

TABLE 6.A. PERFORMANCE

Collected particle minimum diameter| 2 µm typical
Field of view| 3.7 mm x 2.8 mm or 10.1 mm²
Typical particle collection efficiency²³
  >10 µm diameter| >90%
  5 µm diameter| approximately 50%
  2.5 µm diameter| approximately 20%

 Spore class as shown in Table 6. B| 73% typical

Air sampling time per reading| 3 min typical
Time to analyze one air sample reading in cloud| 3 min to 5 min typical

1The minimum diameter of detectable particles may actually be larger or smaller than 2 µm due to the refractive index and the opacity of the particle at the Honeywell Air detective’s light source wavelength (i.e., 850 nm). In some cases, particles smaller than 2 µm may be detected due to high opacity; in other cases, larger translucent particles may not be detected.
2The collection efficiencies indicated are approximations that are derived not from empirical lab characterization, but rather from fluid dynamics models assuming 21 liter-per-minute sampling flow and certain other simplifications, including perfectly spherical particles. The collection efficiencies also assume the use of new cassettes that have been sealed and stored properly at room temperature.
3The collection efficiencies are utilized in the calculation to translate the number of imaged particles to the average airborne particle concentration in

/m 3(i.e., the estimated average number of particles in a cubic meter of

air). For example, a single 15 µm (with 100% collection efficiency) would translate to an approximate airborne particle  concentration of 1 per 63 liters of air (or 16/m 3); likewise, a single 2.5 µm particle (20% collection efficiency) would translate to 5 per 63 liters of air (or 79/m
3).4The precision % values for detailed pollen classes and the spore class reflect the average percentage of correctly detected and correctly identified particles within each of the article classes on which the machine-learning has been trained, based on a comparison between (1) Honeywell laboratory personnel’s analysis of certain particle images derived from lab-generated samples, and (2) the Honeywell Air Detective software’s analysis of those same images. In addition to providing information on these particle classes, the Particle Report also provides insight into (1) the total pollen particles detected (which includes pollen types other than the detailed pollen classes), and (2) the total non-pollen particles detected. Because the Honeywell Air Detective’s machine-learning has not been trained on every type of pollen, spore, or another non-pollen/non-spore particle, and because of the high variability in the appearance of particles in the non-pollen/non-spore particle category, the precision % value is lower for total particles than it is for the detailed pollen class and spore class. The precision % values do not reflect or account for the existence of false negatives (i.e., where there has been a failure to detect a particle in the field of view). For the spore class, the % recall value described in more detail in Note 6 below is a measure of the probability of the Honeywell Air Detective machine-learning algorithms’ detection of particles present within the field of view. Note that the precision % values may not reflect the performance of the Honeywell Air Detective in the field, in particular where a sample taken in the field includes types of particles on which the Honeywell Air Detective’s machine- learning has not been trained. Accordingly, the Honeywell Air Detective’s performance in the field my deviate, even significantly, from the precision % values indicated herein.
5For comparison, an interpretation of the performance of the next best alternative (i.e., impaction sampling and off-line laboratory analysis by a trained technician) suggests that typical coefficient of variation (CV) (calculated as a ratio of the standard deviation to the mean particle concentration) ranges between 10% and 50%. See the following two references for further details on the CV of traditional methods:  1. J. Environ. Monit., 2007, 9, 855-861.
2. American Industrial Hygiene Association (AIHA) “FAQs About Spore Trap Air Sampling for Mold for Direct Microscopical Examination – Mold Analysis Document”, 2020.
6% recall is a standard machine-learning metric used to describe the probability that the Honeywell Air Detective’s algorithms will detect a spore present within the field of view (i.e., avoid a false negative). Recall is calculated using the following formula: (TP / [TP + FN]) * 100%, where TP = True Positive, and FN = False Negative. The % recall indicated was determined based only on the Honeywell Air Detective’s performance with respect to Aspergillus and Penicillium spores and is not indicative of its performance with respect to other spore types. To constitute a “true positive,” the machine-learning algorithm’s prediction must match both the location and identification of the sample analysis conducted by Honeywell laboratory personnel.
7Highly dependent on the cellular connection of HVAC professional’s iPad (standard 3G or 4G service will result in typical analysis times). It is recommended that 2G cellular service be avoided due to much longer upload and download times.

DISCLAIMERS

• Results obtained from the Honeywell Air Detective (HAD) are to be considered preliminary in nature, and a complete analysis of air quality or contaminants would require secondary laboratory analyses. The HAD should never be used as a basis to diagnose a disease or for any other healthcare or medical application. Honeywell makes no representation, warranty, or guarantee as to the accuracy of any detection, failure to detect, identification, or classification of any pollen, spore, or other particle by the  HAD. Any recommendations or decisions with respect to products or services based on the HAD or its results should be made with caution given the preliminary nature of the results.

• The HAD system is designed to improve over time through the advancement of its machine-learning algorithms and the availability and utilization of additional data sets. The product may be subject to inaccuracies, misidentifications, false positives, or false negatives that impact the overall results provided in this report.

• The HAD is not the exclusive method of detecting, analyzing, or identifying pollens, spores, or other particles, and the data that is analyzed – a one-time “snapshot” of the immediately surrounding air in a given location – are not the exclusive source of data relative to particles that may be present. Distinct samples taken and analyzed by the HADin the same location may have a significant variation in the types, classes, and numbers of particles detected. In addition, the particle report does not constitute an etermination as to either the source or viability of any particles detected. The  HAD cannot determine why a particle has been detected or predict whether such particle has been present in the past or will be present in the future. Given theHAD’s performance characteristics, theHAD and the report should not be used as the sole basis for a  comprehensive indoor air quality assessment. Long-term, professional testing with laboratory analysis should be considered to obtain the most accurate assessment of indoor air quality and/or the causes of specific air quality concerns.

• Specific Comments Regarding Spores: The  American Industrial Hygiene Association (AIHA) has cautioned that air sampling of spores alone cannot (1) support any definitive conclusions regarding the presence of mold in an indoor environment or (2) be used to assess potential health risks. Air sampling should be considered only as a  tool used in support of an informed inspection. See https://aiha-assets.sfo2. digitaloceanspaces.com/AIHA/resources/FAQsAbout-Spore-Trap-Air-Sampling-for-Mold-forDirect-Examination-Guidance-Document.pdf. A more detailed evaluation of the origin, identity, location, and/or extent of any spores identified by the HAD can be provided by a professional experienced in mold assessment and remediation. State law mayrequire training, certifications, and/ or licenses in order to conduct mold assessment or remediation services. Where such laws  apply, assessment or remediation should be carried out only by duly licensed and qualified
  professionals.

• It is the buyer’s sole responsibility (1) to determine the suitability of the HAD for use in its application, (2) to operate the HAD in accordance with the user manual and any  other instructions provided by  Honeywell (including, without limitation, disposal of the single-use cassette after each use), (3) to  carefully review the particle report and accurately and completely communicate the contents of the report, and provide a full copy thereof, to the homeowner, and (4) to determine, based on buyer’s experience,  expertise, and other available tools, the suitability of any product or service it may offer or recommend to the homeowner. Any recommendations or assistance provided

• by Honeywell regarding the use or operation of the HAD – through our literature, the Honeywell web site, or otherwise – shall not be construed as representations or  warranties of any kind, express or implied, and such information is accepted at buyer’s own risk, without any obligation or liability to Honeywell, and Honeywell assumes no responsibility for its use.  The information we supply in this user manual

• is believed to be accurate and reliable as of this writing. However, Honeywell may update the user manual from time to time. Honeywell disclaims all implied warranties,

• including those of merchantability and fitness for a particular purpose. In no event shall Honeywell be liable for consequential, special, incidental, or indirect damages, or lost profits, or lost revenues.
