  • NIce but very noisy

    I like this unit because it doesn't have a filter, but it is very noisy.

  • Back it goes!

    This humidifier does not work, period!! Then I tried calling the number given to ask for help and it was not in service! I have contacted Overstock and complained and they will honor my return. However, I am not happy to have to make a special trip to UPS and all that! Not happy!

  • Holmes Humidifier

    Humidifier was advertised to be silant running. When unit is turned on it emitts a high frequency noise that can be heard in the next room.

  • Defective items 2 times

    Very disappointed with the quality on this most recent purchase, I have had to return a second one now because it quit generating mist after a couple of weeks of use. I also had to return one of the 3 right after purchase, because it never worked from the beginning and had a rusty spring on it. I believe Holmes is discontinuing this item and perhaps this is the reason why.

  • Only works a week

    I went through 2 of these machines in a month. Each only worked for a few days. I thought the first one was just defective so I tried the same model from a different store... same problem. I only use these during the night so I don't even run them all day and they still gave out. So frustrating!

  • an easy way to boost humidity!

    The humidifier is very quiet and dispenses mist effortlessly. The only fault we found is there is only one way to refill unit. The reservoir has to be removed completely and taken to sink. Would have liked a opening at the top of unit to make refills easier. It is tall, sleek and works well-does not need a filter which saves money too!

Questions & Answers

Get your product questions answered right here.
  • is there a night light?

  • I have 208sq.ft room can this machine do it/ If not can you refer an ultrasonic that does and that is very quiet.

  • what size room does it handle? my room is 208sq.ft. If this cannot do it please refer ultrasonic that does and is very quiet.

  • Permanent filter?? Are you sure? I have never seen an ultrasonic humidifier that uses a filter... that's what sets them apart. So-called permanent filters for evaporative humidifiers are a misnomer- they are just reinforced paper filters/wicks... not at all permanent if you have mineral-heavy water.

  • does this have a timer on it that you can set for how long you want it to run?

    • No it doesn't

  • is the water tank removable for washing

    • Yes. the permanent filter washes clean easily and can be reused so it never has to be replaced
