Humidifier wick — match wick thickness to the frame rails before force-fit
Humidifier wick
Do not crush a thick humidifier wick into narrow frame rails — match thickness so air passes and the humidifier filter wicks evenly without white-dust shortcuts.
A thick humidifier wick jammed into narrow rails blocks airflow and leaves dry streaks that look like white dust problems. Match wick thickness to the humidifier filter frame so the pad seats without crushing and air can pass evenly.
Match humidifier wick thickness to the frame rails before you force-fit
- Measure or compare the old pad thickness against the new wick before you discard the old one.
- If the new wick is much thicker than the rail gap, return it for the exact model pad — do not compress it with force.
- Slide a correctly sized wick into the frame until edges sit in the rails without bowing the frame.
- Run one cycle and check even dampness across the pad; dry corners after a crush-fit often mean airflow is blocked.
Honest stop: a warped plastic frame that no longer holds any pad square needs a frame kit or unit service — do not glue a wick in place.
