So I live in the Southeast US, in a city with one of the worst springs for those with respiratory allergies. The amount of pollen in the air is enough to cover an entire car with green dust overnight. Thinking of this I've decided to buy an air filter.

Since we rent we can't really install one of those central ones, so I've been looking at portable solutions. After reading extensively on the subject, other than finding out that the ionic ones do more harm than good by releasing ozone, I've yet to find a definitive answer on what is a good air purifier.

Granted, I've found professional grade, hospital use ones that for $1000 but those seem to be overkill. Does anyone here have an experience with different air purifiers? What seems to work well, especially at catching pollen?
