The Disposable medical masks are intended for use by healthcare workers during procedures to protect both patients and healthcare workers against transfer of microorganisms, bodily fluids, and particulate materials. This device is single-use and provided non-sterile.
The Disposable medical mask is flat pleated type mask, utilizing ear loops way for wearing, and they all have nose clip design for fitting the facemask around the nose. The Disposable medical mask is only one model: WSKZ-001 and the color is blue. The Disposable medical mask is manufactured with three layers, the inner and outer layers are made of spunbond polypropylene, only the outer layers' color is blue (colorant: Pigment Blue, CAS number: 147-14-8), and the middle layer is made of melt blown fabric. Ear loops, which is held to cover the users' mouth and nose by two Ammonium nylon elastic bands ultrasonic welded to the Disposable Medical Mask. The elastic ear loops are not made with natural rubber latex. The nose clip contained in the Disposable medical mask is in the middle layer of Disposable medical mask to allow the user to fit the Disposable mask around their noses, which is made of Polypropylene and metallic iron. The Disposable medical mask is sold non-sterile and is intended to be single use, and the intended environment is professional healthcare facility environment. The shelf life of each Disposable medical mask is 2 years. The dimensions of each Disposable medical mask are length 175mm and width 95mm. The dimension of nose clip is length 100mm, and the ear loop is length 170mm.

§ 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.
