The kit contains:

1 x Pre Motor Filter (Yellow Casing & Blue Sponge)

1 x HEPA Filter (Post Filter)

Now your post filter may be a white/grey filter, this kit will still fit as the HEPA filter in this kit offers a better filtration than the white filter. However if you prefer to still have the white filter we sell that as a kit with the Pre filter as well. We also sell the filters individually, however it works out cheaper to buy the kits.
