Question: Does this have a filter or is it filterless?
Document: It also has a filter (we didn't like our filterless one) that the manual says you can soak in water to clean, you don't have to buy a new one the second it gets a little brown. I love that it has a spot for the vapor pads. I put a new one in every other night when my son is congested. He hasn't coughed at all during the night since we purchased this a couple months ago. I think we're going to get one for our bedroom too.
This has a filter, no auto cut off, and hard to clean. I use it at work and won't be purchasing another one.
Decent.... cool nightlight for the kids.... not thrilled with the filter life but its maintenance like anything else....overall a nice humidifier
nice stars, but not enough water output and filter doesn't dry well overnight. kid loves it though, and a good night light.
Works as advertised. Wish it came with a mode that had no light at all. Even the dim blue light of the dial is too bright. Found that if I take filter out of the water each day and let it completely dry no mold problems.
The tank had mold growing in it within the first week of use. This is even after cleaning this thing on daily basis and let it sit for half the day to air dry. Plus you need to buy a filter for this unit!! !
Pros:QuietEasy to useLight isn't too brightCheapCons:Filter gets dirty very quicklyLight alternates between blue, red, green and purple(? )Buy extra filters up front. Mine became dirty/worn out rather quickly.
So with a soggy filter I guess this could explain why the humidity output isn't that great. Bottom line:  if you don't mind emptying the water from the base daily then I guess this would be a good purchase for you. Otherwise it's rather average.
The good :Works as described.Wet the filter, fill it up and away you go.It's quiet on night mode. Not silent but reminds you that it's workingLight feature is cool and like that it can be turned offGood handle to grab to refill with and not spillThe bad:Nothing so far. Is a little big but not a big deal
this thing is crap.total waist of money. no mist what so ever.it even sais no mist on the frount of it.so whats the point. they made it with a hole in the bottom???dumb. has a dumb filter that turned brown after i use. its a night light thats it. and a fan.that is sure to get your little one sick.
Answer: It comes with a filter however u can buy more at Walmart or target it has to be changed once a month
