I made this because I had difficulty finding out the correct way to clean these unusual filters.
This shows the covered variant, once the cover is removed the process is the same. The outer cover should just pull off, it's easier to remove it when the filter is still attached to the carb.
One grubby filter
Remove the outer plastic cover using a flat bladed screwdriver under one of the tabs
Separate the two halves and remove the two pieces of foam. Wash them in soapy water and rinse well. Allow them to dry and then oil them with filter oil. I find that 4T and gear oil also work well, but be aware that some oils will form a emulsion if allowed to get wet. Squeeze the excess oil out to avoid causing a smoke cloud and minor ecological disaster when you next start up your scoot.
To reassemble, push the small disk inside the foam cylinder and push the cylinder back over the inner plastic frame. Then you simply push the outer frame over the top, it should click back into place easily.

If it ain't broke you obviously haven't tuned it enough
