Cool Mist Humidifier Filter Drying Out

I bought my cool mist humidifier humidifier about a month ago. After one months use I changed the filter after I noticed it started to take on a slightly orange/yellow tint and was not absorbing the water as it should. The filter was wet at the bottom where it was sitting in the water (obviously) but was not wicking the water to the top of the filter. Not even halfway up the filter!

I changed the filter following all the direction about pre-soaking, etc. But I am having the same problem with the new filter with it not wicking the water up the filter after about 30 minutes of use. I tried turning the fan down to the lowest setting thinking that maybe I was just pushing it too hard. But I have the same problem on the lowest setting. I used the name brand filters that were being sold with the humidifier at Target.

Has anyone else run into this problem? If so, did you ever get any resolution to it? I am cleaning my humidifier according to the directions and I filter my water before I put it in the humidifier. Someone please help me!

How long are you going between filter changes?

A filter that stops wicking water up and turns orange/yellow is one full of deposits.

It sounds like you have hard water. How are you filtering this water before you use it? Distilled water is the best.

Replace the filter. They don't last forever. Mine normally last a month to a month and a half.

Good Luck

    There is no way this would work, the air is pulled through the filter which is is soaked in order to produce the humidty. Without the filter, the water doesn't reach the area it needs to be for it to create substantial humidity.

We have the same problem on our Kenmore. Since the unit is brand new, we just flipped the filter over after giving it a good soaking first. We feel the humidity rise immediately but not sure how long this will last.

I bought a cool mist humidifier an added 1 gallon of distilled water too the tank. I added 1 teaspoon of baking soda but still no mist. What should i do?

you may need to empty the water that went into the base and retry putting the top tank back on sometimes too much water gets into the bottom and it wont put out vapor. at least mine does that and it is an ionic cool mist humidifier which means uses no filter

I have this same problem. And cool mist humidifiers DO produce mist. I have had my humidifier for a while now (6 years) and have never had any problems.

I have a honeywell humidifier and it only blows out cool air.

If this is a furnace mounted humidifier. Just plug it in and turn it on. I do not know what part of the country you are in. I live in northeastern Ohio. We set out humidistats at aprox. 35% and adjust as needed.
Unplug it for the summer. If it getts muggy in the house or if you get condensation around the doors, windows or window sills. Turn the setting down. If it feels dry in the house, or you have dry skin, nosebleeds, dry eyes or notice static electricity. Turn up the humidistat. Always ajust a little at a time and allow a couple of days between adjustments. It takes time to notice any changes.
IMPORTANT ...change the water panels in it yearly for maximum operation.
Good Luck

I have the evenflo cool mist humidifier, model # 758100. There should be a model number on the unit. As far as replacement filters, you can buy the Holmes humidifier filter, model # HWF62. It's compatible with Evenflo. I bought a 2-pk at Target for $15.99. Hope this helps.
