This humidifier works well and is very easy to fill and to clean. It runs quietly with no leaks, no mess. The filler cap is easy to remove by hand and easy to tighten by hand courtesy of a gasket that goes around the rim. The only problem I have is wicks are hard to find in the size specified for this machine. Most wicks I find are thicker than one inch and even Vornado wicks designed to fit all models do not fit this model. This means I have to order wicks from Vornado or from a supplier that sells this actual humidifier model. Right now I am using a wick that is a bit wider than the one inch needed for this humidifer. It seems to be working okay. It is a Vornado wick, just not the one for this model, but it is what I was able to find. I hope that once this model is sold in more stores the wicks to fit it will be available in generic form.
Okay, there are two sides of this, this is a very reliable and efficient product, however, you do need to change the filter pretty often if you do use tap water, I suggest you boil the water first, let it cool for a while, then poor it all in.
I bought 2 humidifiers for my grandsons to help them from their allergies. These humidifiers are really good and very quiet. I recommend this product especially for children's room.
