I use a Venta LW25 airwasher or a similar model. It performs very well, and there is no expendable wick to replace. It is quite difficult to fully clean, as the main component is an array of thin plastic discs arranged closely together. If I wanted to clean it I would have to use a pipe cleaner to get between the discs. Rather than doing this I have just started submersing it in a bleach or vinegar solution to kill whatever grows on it every 2-3 months. I've also started caring less about it being perfectly clean. My rationale is that it uses evaporation rather than dispersing water droplets, so it should be less likely for whatever grows on it to get into the air. I've used this humidifier every night for about 2 years, and so far I've only gotten sick when I travel away from home. I used to have the honeywell unit described in this post. I don't understand the author's complaints. It was easy to clean. You can open the upper fan compartment from underneath, although I'll admit it does look inaccessible at first glance. I don't know if the author is being hyperbolic, but the fan noise was a low-pitch drone, not too loud and honestly drowned out by other ambient noise. I got rid of mine because I wanted to use it for a bigger room and I wanted something I didn't have to buy a wick for every N weeks.
