Advantages and Disadvantages of Cool Mist Humidifiers

  • Because they do not heat water, cool mist humidifiers use less electricity compared to warm mist humidifiers.
  • This is also why they are much safer to use if you have any children or own any pets. Otherwise, it would be very dangerous to leave the humidifier at the reach of children.
  • Since heating elements are quite expensive, cool mist humidifiers are much cheaper.
  • They are also easier to move around the house, from one room to another, because they come in very portable sizes.
  • Cool mist humidifiers are more prone to grow mold as they often favor the growth of bacteria within the water tank. There is also a high chance that your humidifier develops fungi unless you clean it regularly.
  • All cool mist humidifier operates with the help of an integrated fan. To provide the customer with several fan settings, some humidifiers can have a high noise output if you choose to operate the fan at the highest level.
  • If a cool-mist humidifier cannot filter out the minerals inside the water before releasing air into the room, there is a high chance that these minerals will turn into fine white dust. However, you can prevent this by using distilled water instead of regular tap water.
  • Since most cool mist humidifiers require air filters or wicks, people will often turn away from them, as they require extra expenses with purchasing consumables.

Advantages and Disadvantages of Warm Mist Humidifiers

  • Warm mist humidifiers function by heating water, they are automatically a lot healthier. Heated water will prevent any mold or bacteria from developing inside the water tank.
  • These humidifiers will not require any extra expenses because they do not have any filters that required changing.
  • Because of their warm output, they are really pleasant to use during the winter, when cold causes discomfort inside your own home.
  • Since it does not have an integrated fan to produce a lot of noise, a warm mist humidifier is a lot quieter and will not cause any disturbance during your sleep.
  • They consume more electricity compared to a cold mist humidifier.
  • They are not safe to use around children or animals because of the heated water that circulates inside the device.

Common Holmes Humidifier Issues

Below are some common issues that you may face with Holmes humidifier and you might have to replace few Holmes humidifier parts.

Humidifier not getting water


  • Water Inlet Valve: If the water inlet valve is clogged or defective, the humidifier will not fill with water. Use a multimeter to test the valve for continuity. If the water inlet valve does not have continuity, replace it.
  • Clogged Saddle Valve: Over time, the saddle valve can become clogged with sediment or calcium deposits. Because it is difficult to clean a saddle valve thoroughly or you can easily replace it.
  • Humidistat: Turn the humidistat to the highest setting and listen for a “click.” If you do not hear a click, this indicates that the electrical contacts inside the humidistat are not closing. If you do hear a click, but the humidifier still will not fill with water, it is more likely that another part is defective.

The humidifier drum will not turn


  • Drive Motor: If the drum does not rotate and the drive motor is not turning, check to be certain the motor is getting power from the humidistat. If the motor is working but does not seem to have the strength to turn the drum, replace the drive motor. If the drive motor is clicking or only seems to spin the drum partway before giving up, replace the drive motor.
  • Drive Belt: The drive belt might have broken or stretched out too much. If the motor is still working and the drive belt is in place but seems to be slipping, replace the drive belt. If the drive belt is broken it will have to be replaced.

The humidifier fan not working


  • Blower Motor: Try spinning the blower fan blade by hand. If the fan blade does not spin freely, replace the blower motor. If the fan blade spins freely, use a multimeter to test the blower motor for continuity. If the motor does not have continuity, replace it.
  • Humidistat: Turn the humidistat to its highest setting and listen for a “click.” The clicking sound indicates that the contacts inside the humidistat are closing to provide power to the humidifier. If the humidistat is providing power but the blower fan still doesn’t work, the blower motor itself might be defective.

Humidifier overflowing


  • Float: If the reservoir overfills the float valve might not be shutting off properly. When the float is lifted it should stop letting water into the reservoir. If water continues to flow then the float valve is likely stuck or jammed open and should be replaced.
  • Water Inlet Valve: Once the environment reaches the proper level of humidity, the humidistat turns off, cutting power to the water inlet valve. If the humidistat turns off but the water inlet valve still does not close, the valve might be stuck open.

Humidifier not draining


  • Water Evaporator Pad: The water evaporator pad might be clogged with calcium and other mineral deposits. Once the water evaporator pad is clogged, the water rides along the top of the pad and drips down outside of the water collection tray at the bottom. If water does not exit properly check the water evaporator pad and replace it as needed.
  • Water Line: One of the water lines might be broken or out-of-position. Check the water line from the water inlet valve to the water evaporator pad, and check the water line from the bottom of the humidifier. If the water line is clogged, try cleaning it out. If the water line still leaks after you clean it out, replace the waterline.

Filling a Holmes Humidifier

  • Place it on a flat surface and make sure that it is at least 4-inch away from the wall
  • Lift the water tank straight up to remove
  • Now, fill the water tank with distilled water and place it back
