Product review (5 stars): Humidifier Replacement Wick review (and a confession)
Fantastic! This puts out more moisture than the Honeywell one that shipped with my humidifier EVER did!
The lowest the water level in the tank ever got down previously was 1/2 full,  running at full speed for a couple of hours before bed (I then reduce the speed down by one click while we are asleep) So 8 hours and it used half a tank.
Lately after a few months of use (ok, five)  the level was hardly going down at all (I didn't know you were supposed to switch the filter out so regularly, because at a cursory glance mine looked fine)
So I decided to buy a new filter (confession time now)  YUK! YUK! YUK! when I went to switch the filter out and looked closely at the old filter I discovered some white webs of mould. I am so grossed out! I will switch these filters out very regularly now and add the tank cleaner also. I am so disgusted in myself for not paying more attention, and I haven't quite recovered yet! I keep thinking about all those mould spores in the air.
So if you are new to humidifiers like I was, keep a close eye on your filter, cause the white webs are actually hard to see unless you look closely (shudder)
Anyhow, I have used this new filter for two nights now and both nights the water level was actually down to almost empty (maybe a couple of cups left in the bottom if that)
Only thing is that it might be TOO much humidity, as the carpet around the humidifier is damp now. I have it on the floor near the bed. I wouldn't put this on, or too close to wooden furniture! I am going to need to put something under the humdifier (its probably better to get it off the floor anyhow)
 But I like that I can adjust it down so it's even quieter than ever, while it's pushing out more moisture than ever!
A note on the review who mentioned the metal - this filter looks exactly like the photo. No metal! I think he/she reviewed the wrong item. Or maybe another seller shipped the wrong item. Anyhow, this filter is much thicker than the original but other than that, it looks the same.
New filter, tank cleaner and more diligence, my humidifier is now working better than it ever did.
Oh, and I purchased the Honeywell replacement wick (non-third party) to compare. It hasn't arrived yet but I WILL compare the two and review that one too.
