Does this humidifier require changing a filter??

No it does not...just requires you wash it with warm water every 4 refills.

Great Question :) Actually that is the strength of this model. It does not use a filter. In our home we have used the humidifiers with filters and they always end up molding. Then you are running it in your child's room with mold in the air (not good). We use the one instead and my wife got rid of the other models with filters because of that. She loves it :) So it is very popular and does not use a filter. My kids like it so much they even used it as a fog machine on Halloween. As the seller of this item I have to say thats not its intended use though :) Let us know if you have any other questions :) Thanks Dustin GreatVacs (Seller)

I would say that your unit is defective, yes. I used my humidifier all last winter in my office, and never had this problem.

No, you don't technically have to wash the filter, but when I unscrew it every day to rinse and fill up the humidifier tank, I rinse off the filter. You should carefully read the instructions on the box as to the lifespan of the filter, though. I change my filters out every month. (I can't recall how often they say to change them, but I think it's about 1 month.)

All I know is that I have an older model of the Holmes room humidifier. it doesn't have any code on it. anyway, the filter was too tall, but it did fit. so I cut it in half (very hard to do with chic hands. but I did it) and now I have 2 filters for the price of one! other than all that, I'm happy w/it.

I assume your asking if the filter needed to be replaced and the answer is no. That said, after several weeks of continuous operation there was more dust on the outside of the unit than the filter. I wouldn't recommend this unit to anyone.

When the filter needs changing....yes!!! It's gross. And, the filters don't last long!

No, it has an adapter. I love this humidifier. It works well and is easy to clean

I have not changed the filter in my units yet. I have cleaned them, meaning I have knocked the dust off them. But I have not replaced them. There is a small somewhat fragile one in there that you want to be careful with as I guess there is no replacement. The other is larger, maybe paper although I don't remember for sure. This is the one I have knocked the dust off.

I have checked and I don't believe there is a filter. I think buying a new one is the best option. At least they are pretty cheap.

Master plumber came and installed my humidifier. I asked him the same question you have for me. He said that you will go through a few more filters a year, but not substantial. He also said that that is a good thing because the dirt the filter is catching would be in your house otherwise. The reason is now that you have a higher humidity % in your house the dirt sticks better to the filter and is cleaning your household air better. I agree after one day. The air just breathes clean. Hope this helps and I am satisfied with my unit.

I'm using this humidifier for the 2nd year and I have not had any "white dust". The water in my apartment is very hard water, and their is a lot of mineral deposts that get left on the filter, so I have to change the filter more often. Maybe the filter is good enough so that you don't get "white dust"?

No this does not require a filter. Humidifiers without filters have an option for a filter (ball) in the reservoir/tank, but it's definitely not required for normal operation

I have had my humidifier for three years now and have never had a problem. I think if it were mine I would clean it very,very well with bleach then use water conditioner they sell for them I use the little blue ball and water conditioner both.

No- make sure the filter is in correctly. That caused problems with mine too!
