Found which one they have they had a vax and now have a meacoHi, nearly right it was a Vax purifier/humidifier we had a the time. That was great till it sprung a leak We now have a Meaco purifier/humidifier which has been fine although smaller than the other. Also lots of showers are helpful. One of our macaws has a skin problem and so is basically dandruff, so any bit of moisture in the air helps! Best of luck in finding the best solution!
