Advanced filtration with PLA

I just got my adv. filtration unit installed. It works well and all, but while printing PLA the chamber fan turns completely off and the filtration fan is at ~20%. This means the chamber temp rises to ~34C when printing, which isn't ideal. Before I had installed the adv filtration the chamber fans would keep the temperature at 25C. I had to manually command the printer to turn up the chamber and filtration fans. I just chose to do 100% filter and 40% chamber bc it felt right. Is the low speed for PLA intentional?

I am on 6.3.3, and I have adv. filtration selected in the menus.

RE: Advanced filtration with PLA

Following... I just installed it too.  I have not printed with it yet but I am getting the idea that it might be better to remove it when you are not using it and revert the settings.  I am going to go back and not bundle the extra cord in the back panel and leave the extra wire hanging so I have the length to remove the filter and set it down without unplugging it.  I don't know if this is the intended pattern of use or what?   I feel like a lot more instructions on this thing would be very helpful.  The last step was as clear as mud.  More information on how to use the DIY setting.. etc.  I feel like there seems to be the idea only previous users bought the Core One.  I am not new to 3d printing but I am new to Prusa, and many of the bells and whistles this machine has.  A user manual not just install and set up instructions would be good.

I've had my filtration kit on for a few weeks now. I print primarily in PLA, also some PETG. The chamber is regularly around 35C when printing PLA and I haven't had any issues. Works fine with the stock settings.

RE: Advanced filtration with PLA

I've ordered mine even before any pictures were published and I have to admit it's a very big dissapointment.
I expected in-chamber recirculating solution rather than an on-exhaust one, but ok, fine.

But it looks like it's still not possible to set-up filtration per-filament or have it always on, I print mostly PETG and PLA but I still want filtration

Writing this mostly to bump the topic and keep it afloat as I have no solution to the problem.

A recirculating filtration system has its own downsides, right? Such a system won't work properly when you need airflow for a lower chamber temperature.

One workaround, apparently, is to select your usual PETG and PLA filament profiles, but change the filament type to ABS.
Prusa Slicer has no setting for filtration, it's coded into the firmware.

I didn't test this yet, but it will definitely show an error for filament mismatch.
I'm not sure, if you need to set the filament type in the printer's menu to ABS too.
If yes, it'll require you to "swap" your filament and will push your PLA/PETG through the hotend at 255°C...

Not great, but if you reduce the temperature immediately after the first purge and then pure a bit more, it should be fine.
