West Tec Procedure and Surgical facemasks are intended to be worn by healthcare workers to protect the user and patient against transfer of microorganisms, blood and body fluids, and airborne particulates. The WestTec Procedure and Surgical facemasks are single use, disposable devices provided non-sterile.
The WestTec Procedure and Surgical facemasks are identical with the exception that the Surgical Mask has a Comfort Band to keep the inner layer away from the user's mouth to provide space between the users face and the mask making it more comfortable to wear. Both facemasks are manufactured with three layers of nonwoven polypropylene materials. The facemasks are held in place over the user's mouth and nose by two elastic ear loops welded to each facemask. The elastic ear loops are not made with natural rubber latex. The facemasks have a malleable Nose Band contained in the layers of the facemask to allow the user to fit the facemask around their nose. The facemasks are sold non-sterile and are intended to be a single use, disposable device.
The document describes the acceptance criteria and study results for WestTec Procedure and Surgical facemasks, which are intended to be substantially equivalent to the predicate device, Jingzhou Haixin Green Cross Medical Products Co., Ltd Surgical Mask (K123787). The devices are classified as Class II surgical apparel under 21 CFR 878.4040.
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria for the WestTec facemasks are based on the ASTM F2100 Standard Specification for Performance of Materials Used in Medical Face Masks for Level 2 performance classification.
| Description | ASTM F2100 Requirement for Level 2 Classification | WestTec Masks Performance | Predicate Device (K123787) Performance |
|---|---|---|---|
| Fluid Resistance Performance ASTM F1862 | 29 out of 32 pass at 120mmHg | 32 out of 32 pass at 120mmHg | 29 out of 32 pass at 120mmHg |
| Particulate Filtration Efficiency ASTM F2299 | ≥98% | 98.0% | 99.1% |
| Bacterial Filtration Efficiency ASTM F2101 | ≥98% | 99.7% | 99.8% |
| Differential Pressure (Delta P) MIL-M-36954C | <5.0 mmH2O/cm² | 3.3 – 3.6 mmH2O/cm² | 2.6 – 2.9 mmH2O/cm² |
| Flammability 16 CFR 1610 | Class 1 | Class 1 (Non Flammable) | Class 1 (Non Flammable) |
| Biocompatibility ISO 10993-5, -10 | Not explicitly defined in table but met | Biocompatible | Biocompatible |
2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the specific sample sizes for each test in the test set. However, for the Fluid Resistance Performance (ASTM F1862), the pass/fail criterion refers to "29 out of 32 pass," implying a sample size of 32 for this particular test. The document does not specify the country of origin of the data or whether it was retrospective or prospective.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
Not applicable. The study involves non-clinical bench testing according to established ASTM and ISO standards, not expert assessments of a test set for ground truth.
4. Adjudication Method for the Test Set
Not applicable. As noted above, this study relies on objective measurements from standardized tests, not human adjudication.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No MRMC comparative effectiveness study was performed as this is a non-clinical device performance study, not an AI or diagnostic imaging study.
6. Standalone (i.e., algorithm only without human-in-the-loop performance) Study
Not applicable. This is a study of a physical medical device (facemask), not an algorithm.
7. Type of Ground Truth Used
The "ground truth" for this study is established by the performance requirements and methodologies outlined in recognized international and national standards (e.g., ASTM F2100, ASTM F1862, ASTM F2299, ASTM F2101, MIL-M-36945C, 16 CFR Part 1610, ISO 10993-5 & -10). Compliance with these standards indicates the device performs as expected.
8. Sample Size for the Training Set
Not applicable. This study does not involve a training set as it concerns the physical properties and performance of a medical device, not a machine learning algorithm.
9. How the Ground Truth for the Training Set Was Established
Not applicable. There is no training set for this type of device performance study.

Discussion of Non-Clinical Tests Performed to Determine Substantial Equivalence
The non-clinical tests listed in the above table were performed to determine substantial equivalence. Tests were conducted following the recommended procedures outlined in the following standards. Test results met all relevant requirements in the test standards, and are comparable to the predicate device.
- ASTM F1862 Standard Test Method for Resistance of Medical Face Masks to ● Penetration by Synthetic Blood (Horizontal Projection of Fixed Volume at a Known Velocity)
- . ASTM F2299 Standard Test Method for Determining the Initial Efficiency of Materials Used in Medical Face Masks to Penetration by Particulates Using Latex Spheres
- ASTM F2101 Standard Test Method for Evaluating the Bacterial Filtration Efficiency ● (BFE) of Medical Face Mask Materials, Using a Biological Aerosol of Staphylococcus aureus
- MIL-M-36945C 4.4.1.1.1 Method 1 Military Specifications: Surgical Mask, disposable
- 16 CFR Part 1610 Standard For The Flammability Of Clothing Textiles ●
- . ISO 10993-5 & -10 Biological evaluation of medical devices
Test results show the WestTec facemasks met all relevant requirements of the above test standards. The results also indicate the WestTec facemasks have similar results as the predicate and both meet the ASTM F2100 requirements for a Class 2 Performance Level facemask. More details of non-clinical tests are summarized in Tab 18.
Discussion of Clinical Tests Performed
Not applicable
Conclusions:
The WestTec facemasks and the predicate facemask are similar in size and are made of similar materials, polypropylene coverstocks to encase a polypropylene filter layer. Both the WestTec facemasks and the predicate facemask have the same intended use. Bench testing detailed in this submission demonstrates the WestTec facemasks and the predicate facemask have similar functional characteristics. The technological characteristics do not raise any new questions of safety or effectiveness. Therefore, the WestTec facemasks are substantially equivalent to the predicate device.
§ 878.4040 Surgical apparel.
(a)
Identification. Surgical apparel are devices that are intended to be worn by operating room personnel during surgical procedures to protect both the surgical patient and the operating room personnel from transfer of microorganisms, body fluids, and particulate material. Examples include surgical caps, hoods, masks, gowns, operating room shoes and shoe covers, and isolation masks and gowns. Surgical suits and dresses, commonly known as scrub suits, are excluded.(b)
Classification. (1) Class II (special controls) for surgical gowns and surgical masks. A surgical N95 respirator or N95 filtering facepiece respirator is not exempt if it is intended to prevent specific diseases or infections, or it is labeled or otherwise represented as filtering surgical smoke or plumes, filtering specific amounts of viruses or bacteria, reducing the amount of and/or killing viruses, bacteria, or fungi, or affecting allergenicity, or it contains coating technologies unrelated to filtration (e.g., to reduce and or kill microorganisms). Surgical N95 respirators and N95 filtering facepiece respirators are exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 878.9, and the following conditions for exemption:(i) The user contacting components of the device must be demonstrated to be biocompatible.
(ii) Analysis and nonclinical testing must:
(A) Characterize flammability and be demonstrated to be appropriate for the intended environment of use; and
(B) Demonstrate the ability of the device to resist penetration by fluids, such as blood and body fluids, at a velocity consistent with the intended use of the device.
(iii) NIOSH approved under its regulation.
(2) Class I (general controls) for surgical apparel other than surgical gowns and surgical masks. The class I device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 878.9.
