Hi @pierre-gilles,
I have a Dyson purifier and I think this request is a duplicate of the one concerning the HEPA filter. Indeed, the HEPA filter and the activated carbon filter are the same, so I don’t know if it’s necessary to perform two monitoring checks.

Hi @Nagromdark
on mine there are indeed 2 separate physical filters, one for activated carbon and one HEPA.
I’m following up on this — are you sure @mutmut that you have 2 filters to change? For me on the TP09 there’s only one and it’s stated on the Dyson website that for the TP04 it’s the same. Could you send me what Matterbridge returns to you please?
For example I have this:
The attribute “inPLaceIndicator” is false for me
this is my screenshot of the activated carbon, and for the HEPA filter it’s in this topic.
I have true for HEPA and activated carbon.

I have to admit I don’t understand everything about these filters 
If I go through the Dyson app and click on one of my filters I get this:
so 2 distinct filters. But when I click on the first or the second Acheter, I end up on the dual filter that you show.
I get the feeling my TP04 isn’t very new and that I might have some trouble finding the right filters.
EDIT: they are indeed different models for mine and yours
OK perfect we have the explanation 
For me it’s a 2-in-1 filter that’s worth 100 bucks, basically (a rip-off)
