My room is still dry

I have the U7142 humidifier and I have the humidifier running all night but it never gets above 30 or 35% humidity. I keep it set at 55%. My room is not even close to 800 sq. ft.

Hi, We just purchased a vicks warm mist humidifier. We used it for two nights in my daughter's bedroom...we then noticed a sticky residue over sections of the wall as well as crackling paint? Is this...

is it possible that you have the mist turned up too high? If the room is very small, the high setting could be providing too much humidity to the room. I'm thinking that the paint crackled as the humidity climbed.

If your humidifier is working properly, then the problem lies outside of the humidifier. For example how long does your furnance run when the thermostat calls for heat? If your furnace is oversized for your home, it will heat your home relatively quickly, and turn off, while your humidifier does not have a chance to work long enough for it to increase the humidity. If this is the case, you could try to set the thermostat to run the fan in manual mode instead of automatic. This will give the humidifier a chance to increase the humidity.

Hope this helps.

No matter what setting is put on furnace humidifier, moisture forms on windows.House is only 6 years old and does have a lot of windows.

Hello WPwilkers, Well there's good news and good news!

First off, you should probably use the lowest possible setting as your house being so new, is likely pretty "air-tight" and as such, doesn't have a lot of air infiltration (gaps and drafts) hence the reason you're seeing moisture on the windows.

Now, I would also use a hygrometer, just like your parents likely had hanging on a wall somewhere in their house. It will give you a better idea of the moistur (humidity) around the house. My guess is that you're already at the 60%+ level of humidity.

I suggest that you turn "OFF" the furnace mounted humidifier, until you no longer see moisture on the windows. That will allow the house to adjust and get back to normal humidity levels.

Then you can start by setting the humidifier on the lowest possible setting and keep an eye on the moisture levels in your coldest room of the house, as that is where you'll first notice the excessive moisture on the windows (just the way it works - cold rooms get condensation on the cooler windows first).

If you don't have the humistat (the control for the furnance mounted humidifer) mounted next to your heating and cooling system thermostat, you should do that - it will make it easier to adjust and also will provide a more accurate reading for the humifier to operate properly.

Some Thermostats have the ability to add a humidifier on it for integrated controlling of the furnace humidifer. Check your Thermostat and Furnance owner's manual for details.

I used to have the same problem and found that by moving the humidifer control from the utility room (mine was in the basement of my house) to the living space, it made a big difference. Since most people's homes have unfinished basements and that's where the HVAC system is located, it doesn't get the same humidty readings as an occupied living space.

The other reason that you tend to get moisture (condensation) forming on windows is that the Percentage of humiditfication is set manually with the humidifier control, and yet, the outside (and inside) air temperature vary and the difference between them can cause the humidity levels to go from very dry to very moist, in a day or two.

I tend to wait until I notice that the air inside the house is getting dry and then turn on my humidifier, once the cold winter days have taken hold. In summary, nothing wrong with your unit, just mother nature and a well built (most air-tight) home are giving you higher levels of condensation than most older homes. Gradual adjustments, once you turn the humidifier off for awhile, should get you the desired results.

I hope you find this Very Helpful and best regards!

Dry house, albeit have two april aire humidifiers

The reason you can not run your humidifier while the blower is off, is because all the humidity would condense almost immediately and rot out your duct work. If you find that the humidity provided during the cycle of your furnace is inadequate, I would suggest purchasing a table top unit, and keep it in the room where you spend the most time. So, the answer to your question is no, you can not run a humidifier while your blower motor is off. Hope this helps.

Won't humidify past 30% in a 90sf bedroom

The most probable reason that the humidifier does not reach the levels you describe is because you said you had the unit in your bedroom.

Bedrooms typically contain materials that are known as "hygroscopic." What that means in plain English is that items such as the bedding, mattress, any carpeting, wood, curtains, you, etc. all absorb moisture , kinda like a sponge. Since that moisture is being held by these materials, the air itself contains less by percentage. 25-30% humidity is actually pretty good for any room, especially in colder climates and higher humidity levels can lead to the production of mold, condensation on windows, etc., which are not good things. The good news is that reasonable humidity levels are healthier for textiles such as carpeting, cloth, and so on because the fibers won't dry out and crack. Dust is also reduced, but again, only to a certain level.

If your humidifier is reaching 30% it's probably working ok.

Humidifier not collecting water

To both, these sound like de-humidifiers. Is your goal to reduce humidity and dry your room?

If so, if the humidity is low, then the de-humidifier has no work to do. A cheap battery or dial humidistat will help.

If not, check for a clogged filter. No air moving spells no de-humidification.

Also check for a frozen evaporator coil. Same as above but this requires repairs.

Electric dehumidifiers are similar to refrigerators and window AC's. With the fan running, adjust the setting to a lower humidity setting until you hear the compressor kick in. If it does not even at the lowest setting, check the space relative humidity to make sure it has work to do. If it does, repairs may be as simple as cleaning electric contacts in controls or as bad as a refrigerant leak or compressor failure. If its bad, better to replace.

A humidifier adds moisture. If you have a humidifier and want to keep the static off your clothes and keep your nose from drying out, fill the tanks with water and add biocide.

Please do not view my comments as patronizing. Even seasoned engineers have difficulty grasping humidification.

Install HE220 HoneyWell , humidity not increasing in the house.

You can try installing the water line to your hot water if it is installed on cold line for more humidification. You should make sure your humidistat is up line 6" @least from humidifier for proper humidification measurement.

Short cycling

It doesn't sound like it has failed.

The whole point of the % setting is so that the room holds at that %. When the humidity drops lower than, it will kick in. When it raises to that number it will turn off.

If the on and off is bugging you try raising the percentage. Or lower the temperature of your house. Heating will dry out the air and cause your machine to kick in.

Good Luck.

Water on floor around humidifier

I haven't had any problems with my Vicks Cool Mist Humidifier other than the fact that the area surrounding it is slightly wet after operating for a couple of hours....While I understand that I was using this to moisturize the air during a cold, I knew this would happen, because the air in my room is not dry. If the room isn't dry, the mist that it's putting out in to the air has no where to go but surround the humidifier. All I did to stop this was to buy a water proof mat. I suggest you do the same -- Also, in regards to the water smelling -- You should be cleaning out and drying the basin after every use. Water shouldn't smell unless you let it stagnate inside the plastic -- Try running distilled vinegar through the machine for a couple of minutes -- Also, I would use an extension cord and let it run outside so that your house doesnt smell like Vinegar.
