Pi & Pie Mask

Pi & Pie Mask is disposable ear loop face mask proudly MADE IN USA. 

Each Pi & Pie Mask consists of three layers of fabric. The outer layer and inner layer are made from polypropylene non-woven fabric, and the middle filtering layer is made from polypropylene melt-blown non-woven fabric. Scientific research has proved that the melt-blown non-woven fabric is the most critical layer in filtering out particles and bacteria and in preventing liquid penetration. Therefore, Pi & Pie secures high quality melt-blown non-woven fabric in producing our products.

Scientific research also indicates that melt-blown non-woven fabric’s filtration efficiency will be reduced due to loss of static charge. In order to prolong our product’s shelf life, we use plastic bag packaging to protect the masks from humidity.

There are five (5) masks in each bag. It’s convenient for you to grab and go, every day, every trip.
