Air conditioners with built-in air purifiers, worth it?

moving into a new house soon, and was wondering if anyone had experience with these. doesnit eliminate the need to be a stand-alone version?

also, are some versions of it better than others? plasmacaster/nanoi-X/pure mist/streamer/health air/etc. i notice some do it via shooting small particles out, or mist? some use electricity or something, and some simply catch particles in a filter, etc.

the price with it included or not is like a 5-man difference… but then again it would save space and plug-ins…
