What's your experience with Prusa Advance Filteration for Prusa CORE One?
I print mostly ABS and ASA in a not that ventilated room so am considering adding the Prusa CORE One filter.
https://www.prusa3d.com/product/advanced-filtration-for-prusa-core-one/
Anybody is using it and can share your experience? For example
1. Did you notice any difference in the odor in the room or the chamber?
2. How noisy is it?
3. What is the airflow with the filter, does exhaust the chamber's air? Does it just circulates the chamber's air? Anything else?
4. Does it affect the chamber's temperature or the print quality?
5. How often should the filter be replaced, is it by printing hours? calendar months?, and are there decent third party replacement filters that are reasonably priced?
6. Anything else I should know?
Thanks.

- Don't print ABS or ASA so can't comment
- Very quiet, much more so than the chamber fans it replaces
- Airflow from chamber through filter to outside. It doesn't recirculate
- Used in place of chamber fans to maintain temp
- After 600hrs of use. Prusa sells a replacement filter: https://www.prusa3d.com/product/hepa-filter/

So far, I'm extremely pleased with it.
My printer is odorless using it. My printer is my office in the basement, in the mornings when I opened the door after the printer was running all night I could smell the hot PLA when it was running. PETG less so. Now, it's completely gone. When I open the door, very noticeable now but it's completely gone from the room.
It's super quiet, super slick and has no impact on print quality that I can tell. It just runs in place of the chamber fans. If you disable the filter in the menu, the normal chamber fans run again.
The recommended replacement cycle is every 600 hours. Someone on Reddit pointed out these filters that are a potentially cheaper option than the Prusa ones - https://www.blurolls3d.com/products/blurolls-air-filter-hepa-for-original-prusa-enclosure-xl-mk3s-mk4-3d-printers-air-cleaning,

Thanks @hyiger!
When I print ABS/ASA with the standard prusa profiles, the chamber fans are off.
Doe the CORE One has print hours meter or filter replacement reminder?
RE: What's your experience with Prusa Advance Filteration for Prusa CORE One?
I haven't used my Core One without the filtration kit but I like it very much. My MK4 would smell up the attic, where I also work from home. Now with the Core One you don't notice any smell. Of course it's louder than a MK4 due to the extra fan but I can't compare to the stock encloser fans.
RE:

... well damn. That's a negative ghost rider, and huh...how the hell am I gonna track that now. Hm. I could have noted the hours on my print statistics, but I never got into the habit of doing it because there was some funky bug on the MK4 that doubled the hours or something? I dunno, either way I for some reason have it in my head that the hours number on my printer was completely junk so no idea what it was at when I turned it into a CORE One.
I guess I could start tracking it now, what a pain. Might have to see what I can do within Home Assistant and my integration into PrusaLink for tallying time and putting an alert badge on my main dashboard like our furnace filter...hmmm

I didn't purchase this but intend to dependant on whether it can reliably maintain requested chamber temperature.
Stock with fans when using PETG and stock slicer settings printer is incapable of maintaining 35c chamber temperature. It levels off around 42c. To get it to run around 35c it is necessary to cheat and reduce chamber setting to 28-30c and increase fan maximum setting from 40 to 50% - it is then very noisy! It is consistently around 6 or 7 degrees over what's expected and has been accepted as a bug in Github. The problem appears to be the fan hysteresis. They start far too late during the heating up cycle and they are incapable of reducing the temperature once it goes a few degrees over without being on excessively high. Why is this important - some filaments and colours become very stringy at high chamber temperatures. Prusament Grey PETG is an example, Galaxy Black doesn't care, Orange is somewhere in between. My current fix using grey is remove top cover and reduce stock PETG profile filament temp to 240 which would rather defeat the object of having a filter!
I don't use smelly filaments very often but it would be nice to have the option without annoying my wife 😉
RE:
I mostly print in PETG and with the top vents open the chamber stayed around 35-38 with a 22c ambient. You don’t need to maintain a constant chamber temp with PETG. Maybe just leave the door open? I’ve also disabled the heat soak in g-code when printing PETG and PLA.
