Introducing our Premium cotton face mask, meticulously crafted for durability, comfort, and enhanced protection. This mask is designed with three layers of black cotton for effective filtration against airborne particles. Adjustable elastic ear straps ensure a secure and personalized fit, complemented by a squeeze tight, secure nose clip that enhances overall protection. Each mask includes an internal pocket, allowing you to insert additional layers of protection such as carbon filters, handkerchiefs, or tissues. Optional PM2.5 carbon filters are available, capable of filtering particles as small as 2.5 microns, providing extended protection for up to 72 hours of use. While it's a non-medical device, this mask effectively safeguards against solid particles and droplets, making it suitable for everyday use. For optimal hygiene, we recommend hand washing the mask with mild detergent after each use, ensuring thorough rinsing and drying before reuse.
