Pop Filter is a necessary and effective accessory for professional microphones. It can minimize plosive sounds (heard ′P′, ′B′, ′T′ and ′K′ sounds) that produce a sudden jet of air potentially overloading the capsule and producing a ′popping′ sound. It can be effective to protect the microphone from a spray of moisture as well. Alctron have a wide range of pop filters(Nylon type and metal type) for your choice.
