I just bought SHARP 抽濕機 (HKD$3200). Very good, and very happy with its functions. It dries all the washing in under 2 hours time!! (incl. 2 pairs of jeans!!!)
I bought the Sharp dehumidifier (model: DW-R268A, made in Japan). Quite like it, it dries my clothes very quickly. I washed two pairs of jeans, and it dried in about 2 hours. It has timer as well, so I can set it to switch on before my husband and I get home. So far so good.
