Best Air purifier in 2025?

Hey!

Most of the threads are pretty old and archived… So please allow me to ask for a clue in 2025 for the "best" Air Purifiers with the best bang for the buck and ofc a good HA(CS) integration … preferably without cloud since I am not sure how to block devices through my router (better make sure nobody can set my flat on fire by overdriving my hardware through some shitty cloud security from vendors).

Any recommendations?

Thanks for sharing your experience!
