We are also new to HK and I really got panicked after seeing our bedlinens got heavier and heavier(esp. after laying them out on the balcony hoping the wind will get rid of the dampness). Thanks to all the great advice on this forum I have now done the following:
1. bought a 25 litre dehumidifier yesterday in Fortress(NEO MAX, never heard of this brand but the sales person strongly recommended it) for our 1,183 sq ft flat;
2. bought 8 boxes of dehumidifiers and put them in all wardrobes and shoe case; will replace them as soon as the indicator says so;
3. closed all the windows before turning on all the four aircons(with dry settings on); will switch to the Neo Max dehumidifier once it's delivered tomorrow.
I'm hoping the above measures will help us get through the humid season(s) in HK.
Can someone please let me know how many months in HK are considered humid if I'm being very fussy about the dampness, eg. I'd think it starts from Mid-Feb. this year.
