These plosives may cause popping noises in vocal recordings. Aside from getting rid of pops, microphone pop filters also act as guard for your microphone against spittle that may be unintentionally left on your microphone. Moisture protection is very crucial especially when using condenser mics, which are more delicate than cardioids mics. These purposes make microphone pop filters really recommended in all audio recording sessions, whether for professional or home recording use.
