Review on SHARP FP-A80HFU FZ-A80HFU, 1.500, White by Wayne Lemke

Works well, although it's pricey and really does get dirty fast. I supposed that's a comment on the air quality, but I'd hope that the charcoal filters would catch more to keep the HEPA filter lasting longer.I actually added some sheets of carbon/charcoal on top to assist, and so far it's lasting much longer than the first filter I bought.
