Hi @etrain
Thanks for posting a question.
As this is quite niche, it might not be something another community member can answer, that is unless they have already asked it via another one of our channels. I can provide some insight, however.
Before Dyson introduced the combined filter (COMBI/EVO), Purifiers came with the individual HEPA and CARBON filters. As our technology and software improved over time, we began releasing newer models of our Purifier range. These newer models came with the combined filter as standard, and whilst this new filter type could be used in our existing purifiers, these purifiers have no way to identify that they have this single filter variant. This sits both in the onboard software of the product(s) and the In-App experience.
The online store should have shown you that this combination filter is compatible with your model, and provide you the choice to purchase either this filter type or the standard HEPA and carbon. I am sorry that this wasn’t the case.
I can offer you assurance however that the In-App filter life is calculated using the same metrics. Meaning that the filter life function will still report the correct percentage (%) and percentage (%) decrease over time. This is just shown over both variants on the App screen. Our How is the filter life calculated and displayed in the App? article can help answer any questions you have over this calculation.
I advise you to reset both of these filter types, otherwise you may receive notification that one of the filter is depleted.
I have regular reviews with our development team, so will ensure I bring this up and highlight your comments in our next session. As these Purifier(s) have no way to identify the single use filter, I am afraid that there isn’t anything that can be done to amend the In-App experience.
Could I ask you update your account with your Purifiers serial number? I can use this to highlight your particular model and attached it to the comments I send through to the team.
If you have any question, feel free to @Me in a reply.
Thanks,
Stuart
