Got plate meh? Got filter that normal use need change after the machine tell you to change, roughly yearly.

Non servicable parts?
The filter life is 6000L, your friend taktau what he is selling.
You can just buka lazada see the filter price and details.

the filter like 250ish for the lower end model, if you consider it as yearly maintenance part.. not that berbaloi after factoring the initial cost.
and i doubt there will still sell the filter after 20 years when the plate rosak.
