In brief: HEPA filter

The best type of filter is one that says "hepa" on it - do not get an ionizer. Ozone is produced by machines that advertise things like "mountain-fresh air" and is irritating to the nose, sinuses and lungs.
The various manufacturers make different bells and whistles, but you'll be good if you buy one that says hepa. They are sized based on the size of the room; don't get a bigger one than you need.
