Review on SecureFit 🔒 Ultra Sensitive Earloop Mask by Geoff Cooper

Over the past few months I have bought a number of masks from different companies and finally decided that I have found the perfect mask that will protect me while I work. The two metal nose and chin straps fit my face perfectly. The mask is a bit thicker than the ASTM Level 2 mask, but the breathability is quite good. All in all I would give this product 5 stars. The main problem with the mask is how CrossTex seals the outer waterproof layer, the middle fleece filter and the inner layer that touches the face. Typically, ultrasonic welding is used to heat and slightly fuse three layers of polymer together; However, CrossTex uses too much force, time and/or heat during the process. This leads to the formation of holes where ultrasonic welding has occurred. You can see in my photos that there are holes big enough to fit the tip of a mechanical pencil. Each of the 50 masks in my box has holes in different parts of the mask. Unfortunately, this is another mask you'd better not buy.
