12 Best Humidifiers For Babies

There is a way to get around the problem though – humidifiers. These are often recommended for use when an infant suffers from a severe cold and congestion. But different humidifiers work in different ways. So, how do you know which one to pick? MomJunction gives you a guide on humidifiers, their usage, and lists 12 best humidifiers for your babies.

What Is A Humidifier?

A humidifier is an electronic device that emits water vapor to increase the humidity levels in the air. The device comes with a reservoir to hold water, which gets converted to vapor through an evaporation fan. Humidifiers are available in several forms.

Types Of Humidifiers

There are five types of humidifiers (1):

  1. Central humidifiers are built into a building’s central heating system and use ventilation ducts to pump water vapor. They are expensive and non-portable since they are integrated into a building’s structure.
  2. Evaporators use a “wick” system where a porous pad soaks water, which is evaporated by a high-speed fan to humidify the air.
  3. Vaporizers, also called warm-mist or steam humidifiers, boil water and convert it into steam, which is released into the air.
  4. Impeller humidifiers have a rotating disk that throws water outward with high speeds. The high speeds convert liquid into mist. It works like a spray from a spray bottle.
  5. Ultrasonic humidifiers work similar to impeller humidifier, but instead of a rotating disk, they have a stationary, ceramic disk with water on top of it. The ceramic disk vibrates at high speeds matching ultrasonic frequency, which changes water to gas, and releases from the humidifier as mist.

Except for central humidifiers, all others are portable and can be purchased exclusively for your baby’s room.

Evaporators, impeller humidifiers, and ultrasonic humidifiers expel mist at normal room temperature and thus are called cool-mist humidifiers. Central humidifiers and vaporizers release steam to humidify the air and are warm-mist humidifiers.

Humidifier Vs Dehumidifier Vs Air Filter

People often confuse between dehumidifiers, air filters and humidifiers. However, they have different functions (2) as explained below:

  • Dehumidifiers do not rid a room of excess air moisture. They condense gaseous water into liquid to reduce the humidity in a room. It is used in conditions of excess humidity.
  • Air filters cleanse the air by removing particulate matter such as smoke and pollen by using physical and ionic filters. They do not humidify or dehumidify the air.

Both dehumidifiers and air filters are portable like humidifiers but serve an entirely different purpose. So make sure you are buying the correct thing.

How Does A Humidifier Help A Baby?

Besides keeping the air moist, they benefit babies in many other ways.

  1. Moisturises nasal passages: Dried nasal mucus makes it difficult for an infant to breathe. A humidifier restores the ideal humidity levels, making it easy for a baby to breathe.
  2. Helps alleviate symptoms of cold: The American Academy of Pediatrics recommends the use of a humidifier for infants suffering from cold, cough, and congestion (3). It helps in easier respiration and prevents dry throat thanks to the additional moisture in the air.
  3. Moistens skin: If the baby is prone to dry skin during winters, then a humidifier can help replenish the lost skin moisture.
  4. Eases symptoms of severe conditions: Experts suggest the use of humidifiers to alleviate hay fever, nose bleeding, sinus congestion, and even respiratory syncytial virus (RSV) infections (4) (5). Symptoms of these conditions resemble common cold, thus making humidifiers useful during these situations.

When buying a humidifier, you may find numerous models with varying features. Make an informed choice.

How To Select A Humidifier?

The below points would help you cross check all the important features.

  • Select cool-mist humidifiers, such as impeller, ultrasonic, and evaporators as they release mist at room temperature. Warm mist-humidifiers are associated with burns in babies so steer clear of them (1)The American Academy of Pediatrics is against the use of steam humidifiers for infants (3).
  • Choose timer and auto-shutdown features. A humidifier with a timer and an auto-shutdown feature helps you set time intervals, preventing you from checking on your baby through the night. Auto-shutdown is also good when water reservoir goes empty. Also, running the humidifier too long may cause excess humidity that could be uncomfortable for the baby.
  • Check for humidistat feature. Humidistat is a device that measures and monitors humidity levels in a room. It displays the relative humidity as a percentage on a digital display. A humidistat can be programmed to shut down or go into a low power mode after the room has attained the required humidity. Surplus moisture can condense on the windows and other objects in the room, making the baby’s room damp.
  • Dismountable water reservoirs are helpful. The water reservoir holder should be washed regularly to prevent mold and bacteria. A detachable water tank can be easily cleaned and dried before refilling.

Considering the checklist, we have compiled a list of 12 best humidifiers for your baby.

Tips And Precautions For Humidifier Use

Follow some best practices and precautions even when you are using the best humidifier for the baby.

1. Avoid additives in water:

Many humidifier manufacturers give an air freshener additive that releases scented mist. While adults may like it, you must avoid using it for infants as it could irritate their delicate respiratory lining. Experts also recommend against the use of bacterial disinfectants to the water reservoir as it may contain harmful chemicals that could adversely affect the infant’s lungs (6). Use only water for the mist and stay away from any form of air freshener.

2. Clean the humidifier often:

Even the best humidifiers cannot guarantee the complete absence of bacteria and fungus in the water reservoir. This means you must clean all the components of the humidifier once every two days (7). Start by discarding the reservoir water. Remove the detachable parts of the humidifier, such as the water reservoir and water pad, then soak them in 10% bleach solution. You can use 10% vinegar solution that is nine parts water and one part household vinegar. Soak for 15 minutes and then rinse them well with clean water to remove the bleach or vinegar completely. Dry the parts completely before fitting them together.

Evaporative humidifiers use a wicking pad that could accumulate mold. Use a bottle brush or a scrubber to clean the pad gently. If the pad seems overly dirty or pale, then get a new one. Most manufacturers sell replacement parts that are easily available.

3. Use distilled water:

Several humidifiers feature microbial and mineral filters that clear the water of its impurities. If a humidifier does not have any of these features, then use distilled water, which is free of biological and chemical matter. It serves a dual purpose of preventing contamination by bacteria and inhibits the deposition of mineral scales in the water tank. Scales of mineral deposits can make the reservoir messy and tough to clean. Even if you own a humidifier with built-in filters, you can use distilled water as it will help increase the longevity of the humidifier’s components.

4. Maintain humidity levels between 30% and 50%:

The optimum humidity of a room lies between 30 and 50% (8). Humidity above 50% causes dampness, which is an ideal breeding condition for bacteria and fungus. When humidity drops below 30%, it causes irritation and discomfort in respiration. Several humidifiers allow selection of humidity percentage and some may feature a humidistat that modulates the mist flow automatically. Experts recommend purchasing a hygrometer – a device that measures the relative humidity in the vicinity (9). It gives you the exact water vapor reading and regulates the mist flow accordingly.

5. Place the humidifier beyond baby’s reach:

The American Academy of Pediatrics suggests placing a humidifier close to a baby, but beyond physical reach (3). The best way to do this is to position the device on top of cupboard or table close to baby’s crib, but where the baby cannot touch it. While cool-mist humidifiers pose no burn hazard, they still have moving parts and electrical components that could harm a baby.

Back to top

Humidifiers are unlike other home appliances and require regular maintenance through cleaning. However, when used correctly, they can make a significant contribution to the healthy upbringing of the baby. Always select the cool-mist versions as they are safest for an infant (10). The right cool-mist humidifier can help a baby breathe easy and keep his skin glowing even during the driest seasons.
