Brita Filter Cartridge looks dirty

[blackfluffycat]

Hi. It's not been in long. It looked like there was dust on the top. I've descaled it but it's still there. I can't see what it looks like inside. The other one lasted ages admittedly I never think to change them.
Any ideas? I'm autistic and dyspraxic incase anyone things I'm being daft. Thanks.

As far as I know, they contain a lot of charcoal powder, so a dusty appearance isn't unusual.

I'm not sure descaling it was helpful, what did you use?

When I open a new one, I first give a rinse and a quick soak in fresh water in the washed jug. Pour out that water, then fit it into the slot. Then I run through 2 cycles, discarding the water (give to plants). Then the 3rd cycle is the first I use. If it still appeared dusty, I would assume it was faulty and not properly sealed.

Thank you. DD wants a hot chocolate and I'm
Not sure whether I should use it.
