Hello again.
Today we are going to make an item filter, let's go.

Hopper has 2 functions you should know:
1. Hopper outputs 1 signal with redstone comparator when <=22quantity inside it, outputs 3 signal when
>22quantity inside it.
2. Hopper stops working when it receives signal.

now let's see how to setup:(Notice where these 2 hoppers are facing)

#1 There is a redstone torch under the Hopper2, so Hopper2 won't work.
#2 We place 22 items into the Hopper1, as its quantity <=22, so it only output 1 signal, cannot reach the
torch. Must place them like mine 4/4/4/4/6.
#3 Other items cannot go inside the Hopper1 bc there is no extra space.
#4 If cobblestones go inside Hopper1, the quantity will become >22, it output 3 signal then shutdown the
torch, Hopper2 works now.

Thanks for watching.

Im not sure if the servers does it anymore but hoppers used to send 4 items instead of 1 by 1 (on minevast) which was really annoying?

Good designed but a few flaws, you should add an extra bit of redstone dust on the top so its 3 long (2 then 1) to add overflow protection (if tiling the design). Modified design also by ImpulseSV. In addition you can have 1 named item in the other 4 slots. Adding additional items like you say only decreases the amount of the item you are filtering.
