ACME FILTER MASK INC.
The Surgical Face Mask of different colors (Blue, White, and Green) is a device intended to be worn by operating room personnel during surgical procedures to protect both the surgical patient and the operation room personnel from transfer of bacteria, body fluid and particulate material. This Surgical Face Mask is non-sterilized and disposable.
Acme Filter Mask Inc. Surgical Face Mask with Ear-Loop is flat pleated 3-ply (at least) masks with an inner and outer layer (spunbonded polypropylene) that sandwich a melt blown polypropylene filter material, also with elastic loops. The nosepiece for all Acme Filter Mask Inc. Surgical Face Masks with Ear-Loop are malleable aluminum wire. All the materials used in the construction of the Acme Filter Mask Inc. Surgical Face Masks with Ear-Loop are being used in currently marked devices.
The Acme Filter Mask Inc. Surgical Face Mask with Ear-Loop (K123115) demonstrates substantial equivalence to the predicate device, Modern Healthcare Corp. Surgical Face Mask (K063043), through a series of non-clinical performance tests.

2. Sample Size Used for the Test Set and Data Provenance:
The document does not explicitly state the sample sizes used for each specific test (e.g., number of masks tested for BFE, Delta-P, etc.). The provenance of the data is from non-clinical bench testing performed by Acme Filter Mask Inc. The country of origin for the testing is implied to be Taiwan, R.O.C. where the submitter is located. The study is a retrospective comparison against established standards and a predicate device.
3. Number of Experts and Qualifications for Ground Truth:
This document describes a non-clinical device safety and effectiveness evaluation based on standardized testing. There is no mention of experts being used to establish a "ground truth" in the context of clinical interpretation, as this is a physical product performance assessment. The ground truth for these tests is defined by the technical specifications and performance criteria outlined in the referenced ASTM, MIL, and CFR standards.
4. Adjudication Method for the Test Set:
Not applicable. This is a non-clinical performance study against predefined standards and a predicate device's performance, not a study involving human interpretation or adjudication of results in a clinical setting.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:
No, an MRMC comparative effectiveness study was not done. This device is a surgical face mask, and its evaluation focuses on physical performance characteristics rather than diagnostic or interpretative accuracy that would involve human readers.
6. Standalone Performance:
Yes, a standalone performance assessment was done. The reported performance metrics (BFE, Delta-P, Particulate Filtration Efficiency, Fluid Resistance, Flammability, Biocompatibility) are direct measurements of the device's physical properties and its ability to meet specific standards, independent of human interaction during use. These are "algorithm only" in the sense that they represent the intrinsic performance of the manufactured product.
7. Type of Ground Truth Used:
The ground truth used for these non-clinical tests is based on standardized test methods and acceptance criteria. These include:
- ASTM F1862-05 for Fluid Resistance
- ASTM F2101-01 for Bacterial Filtration Efficiency (BFE)
- ASTM F1215 for Particulate Filtration Efficiency (latex Particle challenge)
- MIL M 36954 C for Differential Pressure (Delta-P)
- 16CFR 1610 for Flammability
- ISO 10993-5 /-10 for Biocompatibility
The "truth" is whether the device's performance meets or exceeds the specified thresholds in these well-established industry standards and compares favorably to the predicate device.
8. Sample Size for the Training Set:
Not applicable. This is a physical product performance evaluation against standards, not an AI/machine learning device that requires a training set.
9. How the Ground Truth for the Training Set Was Established:
Not applicable, as no training set was used.
