With an InvisibleShield antibacterial screen protector, you not only keep your screen free of scratches, but also of bacteria. Because you have your smartphone with you all day and touch it often, a lot of bacteria end up on your screen. The antibacterial technology prevents dirty, unsanitary spots from forming on your screen protector. Some screen protectors have an antibacterial layer sprayed on the outside, but on the InvisibleShield this layer is incorporated in the screen protector itself. As a result, the layer doesn't wear. Even if you regularly clean your smartphone and cover with a cloth, the layer will simply remain in place.
