Question: Does this use a filter?
Document: The humidifier works well and is easy to use. However, I made the mistake of buying the replacement filter cartridge listed on the same page. It does not fit this model! It is for the other Crane penguin humidifier.
I've been looking for a humidifier for my child's room. This one is perfect. It is easy to use and doesn't get any surface in her room wet. Make sure you place on a solid surface and not the carpet because it works better that way. I plan on buying another one. Bonus is there isn't a filter to clean.
I have been using this humidifier for several nights. It is so quiet that you barely know it is on. The mist is very fine and gentle. I have had no problem with leaking or condensation. I have always used distilled water in my humidifiers because we have very hard water in our area. So, I really have no need for an expensive filter. It is super easy to fill and use. Plus, it has the added bonus of being really cute!
We had a cool mist humidifier with a filter that quickly grew all kinds of orange stuff, and warm mist vaporizers that create black shale-like stuff in the tanks, so these penguins are better. I use regular tap water, and we do get a little white dust/mineral deposit film from these (which is much worse with one unit than with the other three), and after a couple months I've noticed stuff starting to grow, mainly in the parts where the mist comes up & out.
This works best me.No more white dust, no more frequent trip to grocery store for distilled water, and best of it, no filter replacement but just my drinking water filter only
This is a excellent humidifier.. I have two kids.. 1 Year old and 5 years old.. This humidifier working so quiet.. you dont need filter..I highly recommend this humidifier.. And very very fast shipping.. Thank You Amazon....
This humidifier came highly recommended from my mother, who bought one for sinus issues. I wanted to get one for the same reason, and because we have a wood stove, combined with forced hot air heat, all which can be incredibly drying.My critieria was simple:  no filter to deal with (been there, done that!) and no wet residue left behind.
We bought two of these for our narrow row house and at first they were working great and we loved the bonus of no filter to clean or change. Then one of them stopped working cometely. Now this may be my fault as the directions clearly state not to move it when there is water in the tank and I did and it hasn't worked right since. The other one of which I never moved while the water tank had water in it is still going strong and worries great.
I would say this is a very good product. Very convinient to use and works very well. So far no issues using this!
Easy to set up. Easy to fill and use. Easy to clean. Plus, its so cute! We have the penguin, polar bear, and pig! Love them all.
