Cleaning And Deodorizing Your Humidifier

How To Make Your Humidifier Smell Nice

It is critical to clean your humidifier because a musty odor often indicates the presence of fungus or bacteria. This is not only unpleasant, but it may also jeopardize your and your family’s health. Here are a few tips for cleaning and keeping this household appliance smelling fresh.

Clean On A Regular Basis
This is the most important way to keep a humidifier in good working order. Without regular cleanings, the appliance will become ineffective, dangerous, and will eventually wear out and stop working entirely.

To clean your humidifier, you must do the following:

  • Disassemble and empty the appliance.
  • Fill the water tank with an appropriate natural cleaning agent.
  • Place the water tank on its base and let it drain into the reservoir.
  • Manually empty the water tank and scrub the inside with a brush.
  • Wipe all other areas with a cleaning agent-soaked cloth or sponge.
  • Rinse thoroughly and air dry.

You should clean this appliance at least once a week, but you can do it as frequently as you like. If anyone in the house is sick or has respiratory problems, you may find that you need it more frequently.

Always Replace The Water
It may be tempting to simply add more water as needed, but you should always empty and replace the water tank. Stagnant water provides an ideal environment for the growth of bacteria and mold.

Furthermore, as the evaporated water was filtered, the old water may have picked up some mineral deposits. Emptying, rinsing, and replacing the tank’s water is always a good idea, and it will help keep the tank and filter clean.

Alter The Filter
If you use your humidifier on a daily basis, the filter should be changed every two months. The filter should be changed every three to four months if used sparingly.

When a filter becomes clogged with dirt, it can no longer filter the humidifier’s output air. It will also promote bacteria growth inside the machine, resulting in a foul odor and air that is unfit to breathe.

Combat Mold And Bacteria
Even with regular cleanings and filter changes, a humidifier is susceptible to mold and bacteria growth inside the machine.

To combat this, add 1 cup of white vinegar, three drops of tea tree oil, or half a teaspoon of hydrogen peroxide to the appliance’s water tank. All three of these products contain antifungal and antibacterial elements that will aid in the fight against mold growth.

Is It Safe To Put Vinegar Into A Humidifier?

While tea tree oil and hydrogen peroxide are safe to use in a humidifier, you may find that running vinegar through a humidifier is irritating to your nose and throat. While there is vinegar in the water tank, it may be best to run the humidifier in a room you are not using.

What Can I Put In A Humidifier To Clean The Air?

You can purify the air emitted by a humidifier by incorporating any of the previously mentioned antibacterial products, as well as essential oils.

Many essential oils have antibacterial, antiviral, and antimicrobial properties, according to research. There are many to choose from, and which of these essential oils you use will depend on your preferences and purposes.

Include Essential Oils
Finally, we recommend adding essential oils to the water tank of your humidifier. It’s a great way to deodorize the machine while also creating your own scent.

Essential oils are natural and healthy, and many of them have strong, pungent aromas that quickly fill a space. Peppermint, clove, eucalyptus, and lemongrass are a few favorites.

Related Issues

We’ve given you some suggestions for keeping your humidifier and home smelling nice, but you may still have some questions about how to use this machine. We’ll address two of the most frequently asked questions below.

Where Should You Put A Humidifier In Your Bedroom?
In general, the precise location of a humidifier is unimportant. What matters is its proximity to the person or people in the room.

A humidifier should be placed at least three feet away from any sleeping person in the room. This is for both safety and maximum benefit. It is less important whether this is closer to the corner or the center of the room.

The only exception would be if you have a particularly large unit, in which case it may be best to place it in the room’s corner, away from the occupants.

Can You Humidify A Room Too Much?
Yes, it is possible to over-humidify a room. Inside a home, the humidity level should be kept between 30-50%. If the humidity level exceeds 60%, this is considered excessive.

If you use your humidifier frequently, you should think about getting a hygrometer to measure the humidity in your home.

What Exactly Is A Humidifier?

When the outside temperature reaches extremes and your furnace or air conditioner kicks on, you may notice that the air around you is dry. This can lead to problems in both your body and your home, such as dehydration, dry skin, coughs, and unhappy house plants.

A humidifier will come in handy at this point. This ingenious machine takes water and turns it into steam before releasing it into the surrounding air.

Humidifier Varieties

Humidifiers are classified into two sizes. Portable and whole-house machines are examples. The size of portable humidifiers varies.

Some are designed to be placed on dressers, while others are so large that they must be moved around the house on rollers.

On the other hand, you cannot relocate entire homes. These machines are also known as central humidifiers. The majority of these appliances are permanently installed in the home’s HVAC system.

However, some units are designed to stand alone in a living area while still providing moisture to the entire house.

When it comes to technology, there are two types. Warm mist and cool mist humidifiers are available. Warm mist humidifiers produce warm, sterile air. Cool mist humidifiers emit filtered, cool air.

Humidifier Uses

Humidifiers have numerous applications in the home. This appliance contributes to the general health of the people who live there, particularly the skin and hair. Using a humidifier to keep the air moist helps prevent dry skin and hair. It is especially beneficial for those who have eczema flare-ups.

Some of the most significant advantages of using a humidifier are in the prevention and treatment of illnesses. Warm mist humidifiers emit sterile steam into the home, and the humidity levels assist in the breakdown of viral air particles.

This prevents infectious diseases like influenza from spreading, which is very appealing when you want to keep one sick family member from infecting others.

Humidifiers can also help a cough stay productive. This is especially important during the healing process after a respiratory illness. A cough that is stagnant and unmoving promotes the development of pneumonia. A productive cough will aid in the person’s recovery and prevent pneumonia.

Humidifier Dangers

While a humidifier is a wonderful piece of technology, there are some risks to be aware of. Some of the negative effects of using a humidifier include an increase in allergens, respiratory illnesses, body aches, and fatigue.

All of these negative effects are linked to unfiltered humidifier air, as well as bacteria and mold. This is usually indicated by unpleasant odors, which is all the more reason to thoroughly disinfect and deodorize the machine.


The humidifier may be a fixture in your home that is frequently used, particularly during the cool winter months, and if it emits an unpleasant odor, this can quickly become a serious problem.

This is not only unsettling, but it could also be a sign of something dangerous. We’ve provided some excellent methods for deodorizing and disinfecting your humidifier for the most effective and pleasant use.
