Pop filters are small instruments that is positioned in front of the mic. It helps prevent alternations due to speaking some letters of the alphabet. So, you only obtain vocal tracks that are clear and crisp. For just $10 to $50, you get an enhanced vocal recording. Even though the instrument doesn't bring magic, it will certainly not just provide you clear sound. It can also provide your mic shield against corrosion due to liquid that is left behind on the mic.
