MDF Doors are Fuzzy

I am trying to make MDF shaker cabinets doors. For right now I’m just using a 1/4, 2 flute downcut bit. I plan to buy the 4 bit shaker door set soon.

The panel comes out extremely furry and no amount of sanding helps.

Can anyone tell me how to get a smooth surface?

Hit it with a primer or glue water then sand
