Query: Noisy and not effective

I am disappointed by this humidifier. I replaced a previous Honeywell humidifier (HWM450 steam) with this "cold" one. It is not only much noisier (think washing machine) but also doesn't increase humidity more than a few percent. Where my previous humidifier was able to increase humidity from 30% to over 50% in less than 30 minutes, this HCM650 takes about 2 hours to raise humidity by 5% - and can't raise the level much further in the following hours. (I used both humidifiers in the same room).I'm mystified Honeywell would label such a noisy machine "Quietcare".I cannot recommend this product.
