THERMOMETER FAQs

What is the best way to achieve an accurate reading from my thermometer?

Digital Sticks
  • Our Vicks Digital Thermometers are for oral, rectal or underarm use. Whichever method is used, it is recommended that for 15 minutes prior to use avoid eating or drinking any liquids, exercising, taking showers or baths or smoking.
Rectal Thermometers
  • Your Vicks Rectal Thermometer is designed specifically for rectal use. It is recommended that prior to 15 minutes before use, your child should avoid eating or drinking any liquids, physical activity or bathing.

How should I clean my thermometer?

The thermometer should be cleaned in between uses, as necessary after oral, underarm, or rectal measurements.

  • Clean the probe tip and protective cover by washing with soap and warm water or by disinfecting with rubbing alcohol (70% isopropyl alcohol)
  • Wipe dry with soft cloth and let air dry DO NOT BOIL OR CLEAN IN DISHWASHER. This will cause the thermometer to no longer function and will void the warranty.

What should I do if my thermometer is reading an 'ERR' messaage?

  • 'ERR' will be displayed if too much movement or any odd behavior has taken place during a measurement. The display will read Err when the tip of the thermometer is being moved while taking a reading. The display will read 'ER1' when a malfunction occurs, and the unit will power off after one minute. The display will read 'ER2' when the reading is outside the measurement temperature range. The display will read 'ER3' when the ambient temperature is outside the operating temperature rang.
  • Here are the optimal ambient temperatures. Operating or storing outside these ranges may negatively impact the measurement and potentially damage the thermometer:
  • Operating environment must be between 59°F -104°F.
  • Operating and storage environment must be between 15-95% relative humidity.
  • Store between -13°F and 122°F.
  • If core body temperature is lower than ambient temperature the reading may be negatively impacted.

HUMIDIFIER FAQs

How do I set up/install my humidifier?

Please refer to the videos tab on your specific models detail page for instructions on how to get started using your humidifier.

How do I clean my humidifier?

Cleaning your humidifier varies by model. Please reference our How to Clean page for instruction videos that are specific to your model.

Where can I buy Vicks humidifiers?

Vicks humidifiers can be purchased online and in-store at the following retailers:
Amazon, CVS, Fred Meyer, Meijer, Publix, Rite Aid, Target, Walgreens and Walmart.


We recommend calling ahead before visiting the store, since product assortment and inventory levels vary by location.

What are the differences between the various humidifiers?

Cool Types
  • Evaporative - Water is wicked up from the base into a porous filter. Air blowing from the fan through the filter evaporates the moisture into the air. With evaporative humidifiers, the mist is not visible.
  • Ultrasonic- Water is turned into a visible mist by the nebulizer moving in the base at ultrasonic speeds.
Warm Types
  • Vaporizer - An electric current passing between two electrodes vaporizes the water resulting in the emission of warm steam.
  • Warm Mist - A heating element boils the water to produce steam.

How do I order replacement parts?

To order parts for your Vicks Humidifier, please email [email protected]

How do I use medication in my humidifier?

Depending on the type of humidifier, Vicks VapoSteam and Kaz Inhalant can be used in the medicine cup while Vicks VapoPads can be inserted into the Scent Pad door. Please look for accessory compatibility in your humidifiers Owner’s Manual, product page, or in the humidifier comparison chart.

Can I use essential oils in my humidifier?

No. Adding essential oils or any other non-recommended materials in the water tank can damage the unit. Oil can erode or eat away at the plastic possibly causing the unit to malfunction.

Where is the best location to place my unit?

Place the unit at least one to three feet away from walls/furniture/curtains etc. Ensure it is not placed where it could be tripped over or in a location where it could be considered a fire hazard. Be sure that it is out of reach of pets and children as the warm mist humidifiers and vaporizers create boiling to hot water.

Are any of the pieces of my humidifier dishwasher safe?

This will vary between humidifiers. Please see the cleaning section of your humidifiers Owner’s Manual, this will inform you if any parts can be placed in the dishwasher.

How often do I need to clean my humidifier?

The unit should be rinsed daily and thoroughly cleaned according to the Owner’s Manual weekly. The unit should also be emptied if not in use and the filter should be dried (if applicable).

What is the white dust my humidifier is producing?

With some humidifiers (Impeller and Ultrasonic) the mist put out by the unit is a visible mist. These types of appliances turn the water into a mist and release it into the air. The minerals that are in the water are also in the mist being released by the humidifier. As the moisture evaporates into the air, the minerals are left behind and will settle around nearby surfaces as dust, and in most cases it is white. It is not harmful in any way; it is just the mineral contents of your water. The amount of white dust you see is directly related to the hardness of your water. To reduce the amount of white dust, use distilled or purified water or Protec Demineralization Cartridges (available for select models).

Why is there condensation on my walls, ceiling, windows, etc?

The humidity level in the room or the house is too high, and the air is becoming saturated with water. We recommend waiting to use the unit until the moisture level drops or using the unit on a low setting. A hygrometer can be helpful in determining the actual room humidity and should be available at most Hardware stores.

Where can I recycle this product?

EVAPORATIVE, FILTERED COOL MIST HUMIDIFIERS

Why is there no mist or steam coming from my unit?

Dry air is pulled through the system and a fan disperses invisible, moisture balanced air. There is no mist emitted. When operating normally you will feel only cool air coming from the unit. Monitor the water level in your tank and base. If you notice a decrease in the water tank over 24 hours, then the unit is operating normally.

How often should I change the filter?

The frequency in which the filter should be changed depends on the water in your area and how often you use your humidifier. If you notice a change in color or a slight odor, then it's probably a good idea to change the filter. For new filters, click here.

Which filter fits my humidifier?

The Protec Replacement Wicking Filter works with most Vicks® Cool Mist Humidifiers. These filters are antimicrobially treated to prevent the growth of mold and bacteria. Please see your humidifiers Owner’s Manual or product pages for this information.

How do I care for my filter?

If mold growth is an issue, we recommend using the Protec™ Cleaning Ball or Fish in your water tank and make sure to never leave your filter sitting in the water if the unit is not on. Whenever you turn your humidifier off, remove the filter and allow it to air dry. If you have a unit with no automatic shut off, you can empty the unit and turn it on with no water in it, allowing the fan to dry the filter out.

It is completely normal for your filter to discolor with each use. Yellow, brown, or rust colored discoloration happens because the filter absorbs all the minerals out of your water. If you flip the filter, from top to bottom with each filling of the tank, you will get much more even saturation and the longest life out of your filter.

Make sure you never add any chemicals to your filter and don't try and clean your filter with anything but cool water. Do not squeeze the filter to dry it out.

Be sure to use genuine Protec™ Wicking filters that are antimicrobially treated to prevent the growth of mold and bacteria.

ULTRASONIC, FILTER FREE COOL MIST HUMIDIFIERS

Why is there white dust?

With ultrasonic humidifiers the mist put out by the unit is a visible mist. These types of humidifiers turn the water into a mist and release it out into the air. The minerals that are in the water are also in the mist being put out by the machine. As the moisture evaporates into the air, the minerals are left behind and will settle around the room as dust, and in most cases it is white. It is not harmful in any way; it is just the contents of your water. The amount of white dust you see is directly related to the hardness of your water. To reduce the amount of dust, distilled or purified water can be used in your machine.

Why is there condensation on my walls, ceiling, windows, etc.?

If there's condensation, then the humidity level in the room or the house is too high, and the air is becoming saturated with water. We recommend waiting to use the unit until the moisture level drops or using the unit on a low setting. A hygrometer can be helpful in determining the actual room humidity.

Why is there no mist or steam coming from my unit?

The nebulizer, or white circle, that you see in the bottom of the base vibrates at ultrasonic speeds to create the mist that this unit gives off. Minerals from your water will collect on the nebulizer and once they harden, the nebulizer slows to a pace that is too slow to create mist. Clean the nebulizer every week to ensure proper functionality.

WARM UNITS

Where do I put the VapoSteam?

The VapoSteam can be used with the Warm Mist or Vaporizer units and should be put into the medicine cup on top of the unit. Do not place directly into the water tank.

The light on my Vaporizer is on but there's no steam.

Vaporizers require water with some minerals content in order to function properly. If you have filtered water or are using distilled water, this can prevent the unit from steaming. If you are using distilled water, please switch to tap water and try again. If you are using tap water and this does not work, we recommend adding one or two pinches of salt (1/8 tsp). Wait ten minutes for the salt to have an effect, and if it is still not generating steam, or is only generating a little steam, then add a pinch or two more as needed, up to 1/2 tsp.

Why is there no mist or steam coming from my Warm Mist Humidifier?

First, make sure there is water in the tank. (Is the reset light on?) If there is water, check to see if there are mineral deposits on the heating element or removable water tray. If there is mineral built up on these parts, it can make the unit shut down prematurely. Please follow the cleaning instructions in the Owner’s Manual and then try to run the unit again upon completion.
