This is a modification for the Ozito 12L 1250W wet/dry vacuum to adapt a Karcher WD2 compatible HEPA filter.
It may work for the 20L version as it looks like it takes the same filters. If someone has one try it out and let me know!
Note that this makes your vacuum “dry” only.

I got fed up buying substandard filter bags to use with my vacuum and didn't want to buy one that had a HEPA filter as I already had a working vacuum. This adds the HEPA without having to get an entirely new vacuum!
You have to remove the existing basket from the vacuum and replace it with this one.
Best done with a flathead screwdriver and a bunch of care - leverage off the old basket by undoing the 3 clips around where the original filter should go.
A gasket shouldn't be required but you can easily add one if you find you need one using silicone or a big O-ring.
