The Surgical Face Mask is intended to be worn to protect both the patient and healthcare persomel from transfer of microorganisms, body fluids, and particulate material. These face masks are intended for use in infection control practices to reduce potential exposure to blood and body fluids. The face mask is single use, disposable device, provided nonsterile.
The Surgical Face Mask is flat pleated style mask, utilizing ear Loops way for wearing, and they all have nose piece design for fitting the Surgical Face Mask around the nose. The Surgical Face Mask is manufactured with three layers, the inner and outer layers are made of spun-bond polypropylene, only the outer layers' color is blue (colorant: 29H,31H- phthalocyaninato(2-)-N29,N30,N31,N32 copper, CAS number: 147-14-8), and the middle layer is made of Melt blown polypropylene filter. Ear loops, which is held to cover the users' mouth and nose by two Spandex elastic cord and chinlon ultrasonic welded to the Surgical Face Mask. The elastic ear loops are not made with natural rubber latex. The nose piece contained in the Surgical Face Mask is in the middle layer of Surgical Face Mask to allow the user to fit the Surgical Face Mask around their noses, which is made of steel wire and polypropylene. The Surgical Face Mask is sold non-sterile and is intended to be single use, disposable device. The dimensions of each Surgical Face Mask is length 17.5cm±1cm and width 9.5cm±1cm. The dimensions of nosepiece is length 115±1 mm and width 3.0±0.5 mm, and the ear loop is length 180±10 mm and width 3.0±0.5 mm.
The provided text describes the regulatory clearance of a Surgical Face Mask (Model: METH-03) through a 510(k) premarket notification. The document focuses on demonstrating substantial equivalence to a predicate device, primarily through non-clinical bench testing.

§ 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.
