Higher price != better printer.
My Qidi Q1 pro has has lots of print quality and reliability problems. I ended up fixing them by disabling lots of printer features, including filament width detection piezo bed height sensor. Despite it being housed I had to do a lot of modifications to duct it properly because it has lots of holes and fans.
My $300AUD bedslinger i3 clone has only ever had two problems, the non-metal hot end having PTFE tube expansion (great since I replaced it) and the gantry getting crooked (once I knew this it became 1000x easier to use). Not as fast acceleration as the Qidi but much more reliable.
I borrowed a Mk3 Prusa from work a few years ago. If I had to pay for it I would have been really pissed, out of the box it was really slow.
My old boss spend thousands on an even slower printer… lets not go there :D
I’ve heard that even the Enders are much better out of the box these days. Maybe try one of those?

Tiny filters are a scam in the soldering world too. A few mm thick sheet of carbon impregnated open-cell foam isn’t going to have even a 50% impact on the fumes. Proper rated fume filtration systems are between the size of a large dog and a washing machine; and cost crazy amounts of money.
Plumbing it outside is cheap, extremely effective, small and if something breaks you can tell immediately.
