so I was wondering if I need to get an air purifier for when I get myself a parrot. I know for a dusty bird they're a must just for the dust, but for oily birds are they necessary? Though I might get one anyway as I'm fairly near a main road and get hayfever a bit. I was also wondering if there's stuff I need to look out for with them? I've seen that the ionizing ones are bad for them and naturally the ones with air freshener shouldn't be used but are those the only drawbacks? Also is there a place that would be best to place one? Near the cage or the other side of the room?
