VBA Set Multiple Filters - excel

Question

I've used filters manually, but never with VBA.
I have the following:
K2 - Item 1
L2 - Item 2
M2 - Item 3
N2 - Item 4
O2 - Item 5
P2 - Item 6
Q2 - Item 7
R2 - Item 8
S2 - Item 9
T2 - Item 10
then underneath each user with their Item. Some may have multiple items (i.e. P, R, S & T).
I want to create a "Drop down" (Which I can do haha) where it'll have the 10 Items in it, and when you select an Item, it sets all the filters to blank, but the one Item it, that's been selected, is the only one showing.
Currently doing it manually, but doing it for 10 different items is becoming a head ache!
Just looking to see if someone can point me in the right direction before I spiral down the rabbit hole?
Cheers
Edit:
Have started to try this code, and it does work, but takes forever to process (Downside of having 20k+ lines of data to sift through!)

But I have Filters on all the Headers, was wondering if it'd be smarter to use the Filters rather than the above code!
If so, where would I look at to play around with filters?
