A standard pop filter is fine for Julia Jacklin's vocal fry.

The vocal fry in “Hiro” doesn’t change pop filter requirements. Pop filters stop plosives (p, b, t) from hitting the diaphragm — fry is a low, creaky sound at the bottom of your range, not a blast of air. Any decent cloth pop filter will handle it.

Mic placement matters more. Fry tends to push your voice closer to the mic (you naturally lean in). That causes proximity effect — too much low-end boom. Pull the mic back an extra 4–6 inches from where you’d normally sing. Then the fry sounds intimate instead of muddy.

Don’t overthink the gear. A $15 pop filter and a slightly farther mic stand will get you there.
