Our Product Goals CleanSlate UV is designed to sanitize mobile devices – smartphones, tablet, spectralink phones, Ascom Myco, etc– in a 30 second timeframe. We have validated the efficacy of the device via a 3rd party EPA-certified lab (Microchem Laboratories™). Below is a top-line summary of the results. In the appendix files, you will find full study reports. In the coming months, CleanSlate UV will be working with clients in healthcare and food processing to publish facility-led case study/evaluation results and will be conducting an academic clinical efficacy study, to be published in a peer-review journal. We take the efficacy of our solution and proper device sanitization very seriously. If there is any additional testing or documentation that your facility would be interested in, please do not hesitate to reach out.

ASTM E1153: General Information

ASTM International, formerly the American Society for Testing and Materials (ASTM), is aninternationally recognized organization that develops and publishes product and testing standards.ASTM E1153 is a quantitative test method designed to evaluate the antimicrobial efficacy ofsanitizers on pre-cleaned inanimate, nonporous, non-food contact surfaces. The method istypically used with a maximum contact time of 5 minutes, during which the sanitizer reduces theconcentration of viable test microorganisms. ASTM E1153 utilizes non-antimicrobial agents ascontrols to establish baselines for microbial reductions. The ASTM E1153 method is a benchmarkmethod for non-food contact surface sanitizers and is recognized by several regulatory agencies asan approved method for claim substantiation. See study modifications for changes made to thestudy method to accommodate a device.

Laboratory Qualifications Specific to ASTM E1153

Microchem Laboratory began conducting the ASTM E1153 test method in 2007. Since then, thelaboratory has performed hundreds of ASTM E1153 tests on a broad array of test substances,against a myriad of bacterial and fungal species. The laboratory is also experienced with regardto modifying the test method as needed in order to accommodate customer needs. Every ASTME1153 test at Microchem Laboratory is performed in a manner appropriate for the test substancessubmitted by the Study Sponsor, while maintaining the integrity of the method.

Test Microorganism Information

The test microorganism(s) selected for this test:

Page 4 of 13

Bacillus subtilis ATCC 6633This bacteria is Gram-positive, rod shaped, capable of forming endospores. Endospores of Bacillus subtilis can tolerate harsh environmental conditions such as UV exposure and high temperatures. Typically found in soil, this species is not known to cause disease in healthy individuals, but can be considered an opportunistic pathogen among the immuno-compromised. Bacillus subtilis endopores serve as one of the models for evaluating the effectiveness of sporicides and sterilants.

Clostridium difficile ATCC 43598 (endospores)This bacteria is a Gram-positive, rod shaped, endospore generating obligate anaerobe. Clostridium species are part of the normal human gut flora that produce spores which are highly resistant to chemical and environmental conditions. C. diff is commonly associated with hospital acquired infections and is know to cause antibiotic assisted colitis. Because of it's high resistance to antimicrobials, C. difficile is a benchmark bacteria for sporicidal and sterilant activity of chemicals.

Diagram of the Procedure

Summary of the Procedure

● The test microorganism is prepared, usually by growth in liquid culture medium.● The test culture may be supplemented with an artificial soil load, such as horse or fetal bovine

serum, for one-step cleaner/sanitizer claims.● Sterilized carriers are inoculated with a volume of the test culture. Inoculated slides are dried.

Only completely dried carriers are used in the test.● Test carriers are treated with the test device and incubated for the predetermined contact time.● Control carriers are treated with a buffered saline solution and are allowed to sit for the

predetermined contact time.● At the conclusion of the contact time, test and control carriers are chemically neutralized.● Dilutions of the neutralized test substance are evaluated using appropriate growth media to

determine the surviving microorganisms at the respective contact time.● The effect of the test substance is compared to the effect of the control substance in order to

determine microbial reductions.

Criteria for Scientific Defensibility of an ASTM E1153 Study

For Microchem Laboratory to consider an ASTM E1153 study to be scientifically defensible, thefollowing criteria must be met:

1. The average number of viable microorganisms recovered from the control carriers must beapproximately 7.5 x 105 cells/carrier or greater.

2. Ordinary consistency between replicates must be observed for the control carriers.3. Positive/Growth controls must demonstrate growth of appropriate test microorganism.4. Negative/Purity controls must demonstrate no growth of test microorganism.

Passing Criteria

Due to the modified nature of testing, the study sponsor may determine success criteria.

Study Notes

Device was turned on and allowed to warm up for approximately five minutes before testing. The carrier holder was processed through the device three times prior to testing to check for device functionality and UV bulb operation.

Carriers were dried at ambient (room) temperature (~23°C) for 20 minutes or until visibly dry. Carriers were aseptically placed onto the carrier holder immediately after drying. The device operated on a 30 second cycle, so the one minute contact time was two cycles and the three minute contact time was six cycles.

Carrier holder was elevated approximately one quarter inch from the quartz glass surface toprevent the bottom facing carrier from touching the glass to minimize microorganism transfer fromthe surface of the carrier to the quarts glass surface of the device.

Test Microorganism Information

The test microorganism(s) selected for this test:

Page 4 of 14

Staphylococcus aureus (MRSA) This bacteria is a Gram-positive, cocci shaped, aerobe which is resistant to the penicillin-derivative antibiotic methicillin. MRSA can cause troublesome infections, and their rapid reproduction and resistance to antibiotics makes them more difficult to treat. MRSA bacteria are resistant to drying and can therefore survive on surfaces and fabrics for an extended period of time and therefore makes this bacteria an excellent representative for antimicrobial efficacy testing on surfaces.

Salmonella enterica This bacteria is Gram-negative, rod-shaped, facultative anaerobe. Like the closely related Escherichia genus, Salmonella are common to all parts of the world and share habitats in the digestive systems of cold and warm-blooded animals. S. enterica is one of the most common bacteria associated with zoonotic and foodbourne illness. Because of it's regular occurrence and pathogenicity, S. enterica is a common bacteria for measuring disinfectant efficacy.

Listeria monocytogenes This bacteria is a Gram-positive, rod shaped, facultative anaerobe that is motile due to the presence of flagella. These bacteria are common cause of the foodbourne illness listeriosis, which can be fatal. Listeriosis can cause meningitis and sepsis and is particularly dangerous to pregnant women and unborn infants. Listeria monocytogenes is pervasive and can be found in soil, water, and certain livestock animals. They can resist both heat and freezing and can survive for several years.

Escherichia coli O157:H7This bacteria is a Gram-negative, rod shaped, facultative anaerobe commonly found in the gastrointestinal tract of mammals. Although most serotypes of this microorganism are harmless there are pathogenic groups of E. coli such as enterohemorrhagic (EHEC), verocytotoxin producing (VTEC) and Shiga-like toxin producing (STEC) that can cause a multitude of illnesses. E. coli is relatively susceptible to disinfection when dried on a surface, yet it can be a challenging microorganism to mitigate in solution.
