The present invention relates to a face mask for wearing over mouth and nose of a user, comprising a flexible body portion (11) and one or more fastening means (12) attached to the body portion (11). The body portion substantially covers a respiratory tract opening e.g. mouth and nostrils, of the user to block an entry of undesired airborne impurities into the respiratory tract opening. When the mask (10) is worn, a front surface of the body portion (11) is exposed to an external atmosphere and a rear surface of the body portion (11) comes in substantial contact with the face. The fastening means (12) holds the body portion (11) against the face when the mask (10) is worn.

A face mask can both actively cancel sounds and passively attenuate sounds spoken by the user to prevent the sounds from reaching non-intended recipients positioned near the user. The mask can not only reduce the user's voice from escaping the mask but can also be used to reduce external sounds from reaching inside the mask. Thus, a user can wear the mask in public and talk on their phone without disturbing others around them. The mask can include at least one microphone and at least one audio speaker disposed inside and/or outside the mask. Sounds received by the microphone can be processed by a microphone and computing electronics to provide an output to the audio speaker that can appropriately attenuate the sound received by the microphone, via acoustic cancelation. The mask can not only be used to cancel sounds but may also be used to amplify sounds when desired.

A protective garment, such as a scarf, is provided having a first section and a second section that are detachable from one another. The first section, when detached, forms a fabric tube that may be worn over a user's nose and mouth as a gaiter or religious face and head covering for providing air filtration, while the second section continues to be worn as a garment. The first and second sections may then be reattached to again form a continuous garment. The first section may include an air filter pocket for insertion of a removable air filter to provide increased filtration. The second section may include accessory pockets.

An anti-propylene mask and method for preparation thereof is provided; the anti-propylene mask includes a fiber cloth contact layer, an antistatic non-woven fabric layer and a fullerene/nano titanium dioxide spunbond layer which are arranged in sequence; the fullerene/nano titanium dioxide spunbond layer is made by spun-bonding the modified resin material into a fiber web; the raw materials of modified resin materials include matrix resin, carboxylated fullerene derivatives, nano titanium dioxide, a lubricant, and a coupling agent; the modified resin material is prepared by following method: the carboxylated fullerene derivative is mixed and reacted with the nano titanium dioxide to prepare the carboxylated fullerene derivative-modified nano titanium dioxide, which is then blended and extruded with the remaining components in the raw material, and thus prepared. The mask can prevent propylene from entering the human body through the human respiratory organs and has a good anti-propylene effect.

The sterilization mask with UVC reflective chamber includes a chamber with reflective liner, through which inhaled and exhaled air passes. The reflective chamber is also referred to as a sterilization chamber. Using a reflective chamber ensures each photon of UVC light has a long life, thus dissipating slowly. Increasing the life of the UVC photons decreases the quantity of photons that must be created. Thus, less power is required to achieve the sterilization. Sterilization is defined as a 6-log reduction (99.9999%) of various microbes including viruses, bacteria, and spores. The reflective chamber is made reflective using an UVC internal reflective surface. This surface is preferably formed from ePTFE, or other equivalently UVC reflective material.

The disclosure relates to a mask including a perforated exterior shell sized to cover the nose and mouth of a user and constructed of one or more fabric layers, and a removable multi-layer nonwoven fabric insert sized to cover the nose and mouth of a user and adapted for abutting contact with the exterior shell, the nonwoven fabric including a layer of a spunbond material and a layer of meltblown material adjacent to the layer of spunbond material.

The invention relates to a modular, portable, air purifier device capable of supplying filtered or otherwise conditioned airflow to an individual. More specifically, the present invention provides an air purification system that allows for the remote detection and analysis of local ambient air quality and transmit that information to wirelessly connected devices.
