After some research I seem to be in the minority here, but I've noticed a strange smell emitting from our Health Pro Plus unit? Similar to a car's air conditioning when the engines off, and the air is circulating inside - a fusty like smell. At first I thought it would go away but several weeks later this wasn't the case and even though i tried to get used to the smell, after a day out of the house and being outside, coming back home every night, the annoying smell would just hit me again.
I called my local dealer but they had never heard of this problem before, even though I had with a quick 5 minute google search. Yes i know the manual suggests any strange smells that emit from the unit aren't un-common, it also states that they will go away after time.............well i waited 4 months.
This all hapened to me over a year ago now and since then i've purchased an Austin Air and couldn't be happier. The IQAir health pro pus does look better and has won more awards, but if you ever experience a strange smell, be worried! or buy nose plugs
