Title: Nearly useless
Review: The main reason that I bought this unit is because it has a permanent filter. It's advertised as being easy to clean. That's because it never gets dirty! The permanent filter doesn't pick up anything. It's supposed to give particles an electrical charge so that they'll stick to the filter but it doesn't seem to happen. Honeywell has discontinued this model (60001) and the smaller one (60000) and apparently has given up on the whole technology they use and gone back to units with replaceable filters.
