Inspire Masks was created to do something more than just make a high-quality face mask - we set out to inspire others. Because of this, we make our masks with unique and fun designs that will bring hope and joy to you. Each mask is washable and made from durable, double-layer Poly/Cotton fabric, so you can reuse it over and over. Each mask includes four PM 2.5 carbon filters so you can change the filter as needed. These filters can be ordered in bulk and easily inserted into the mask through a secured opening. Filters are designed with 5-layer construction and are inserted into the front of the mask. Our cloth Adult masks are made to fit different face shapes and sizes securely and comfortably. Each mask has adjustable elastic ear straps and metal nose pieces that can be pressed to tightly fit around your face.
