Hello,
I have a TP09 (newer Formaldehyde purifier) and a slightly older DP04. The DP04 used to consume both a separate carbon filter and HEPA filter, but Dyson have since implemented an all-in-one Carbon+HEPA filter, which I am using in my DP04.
The slightly annoying thing is that Dyson have not yet implemented a visual solution to the change in filters being sold, so both the machine itself and the app show that 2 separate older style filters are needed, and while the counters are reset once in a blue moon, it would be fantastic if Dyson changed the software on the purifier and the app to show just the need for one filter. I understand that the counter is just the same as the older one, but it’s slightly poor that Dyson have ignored this, especially as it’s a consumable.
Are the Dyson software developers aware of this, and are there any planned changes to upcoming software releases, both for the purifier itself and the app to communicate the new type of filter, and align all of their purifiers with this new unified all-in-one filter?
