Living Air Model # XL15

I called with this problem, and after explaining that I did everything I was supposed to do, including vacuuming the inside and outside, cleaning the wire with at LEAST 20 up & down strokes, and cleaning the plates with hot sudsy water, allowing 24 hours to dry and the holding down the power button to reset the unit for 10 seconds; the near-English speaking tech asked me if I had done each step (individually) that I JUST TOLD HER I did. She asked me if I had the original store receipt (which I couldn't find at the time I was on the phone) and then told me that they would send me another one for $29.95 freight plus I would have to pay for return shipping of the original (2-month-old) unit. At this rate of exchange I could just buy another brand new one in less than a year.
