Miking things up close can cause various air-related issues. The most common are the plosives in speech and singing, which cause a low-frequency boom.
This is particularly problematic with cardioid condenser mics, so hand-in-hand with that purchase should come a pop shield. These aren’t too expensive and can be bolted onto the mic stand itself - much easier than fiddling around with homemade efforts.
In a similar vein, if you’re recording anything else that creates strong air movement, you may find a more typical foam wind shield helpful.
