If you have a baby or are expecting one, you may be wondering if you need a humidifier for your nursery. A humidifier is a device that adds moisture to the air, which can help your baby breathe easier, especially during the cold and flu season. Humidifiers can also prevent dry skin, chapped lips, nosebleeds and other discomforts caused by dry air.
But with so many humidifiers on the market, how do you choose the best one for your baby? In this blog post, we will review some of the best humidifiers for babies in the UK in 2024, based on their features, performance, safety and customer reviews. We will also give you some tips on how to use and maintain your humidifier properly.
What to Look for in a Humidifier for Babies
When shopping for a humidifier for your baby, there are some factors that you should consider, such as:
- Type: There are two main types of humidifiers: cool mist and warm mist. Cool mist humidifiers use a fan to blow air through a wet wick or filter, creating a fine mist that cools the room. Warm mist humidifiers use a heating element to boil water and release steam that warms the room. Both types can increase the humidity level, but they have different pros and cons. Cool mist humidifiers are generally safer for babies, as they don’t pose a risk of burns or scalding. They are also more energy-efficient and less prone to bacterial growth. However, they can be noisy and require more frequent cleaning and filter replacement. Warm mist humidifiers are quieter and can help soothe coughs and congestion. They also don’t need filters and are easier to clean. However, they can be dangerous for babies if they tip over or if your baby touches them. They also consume more electricity and can make the room too hot.
- Size: The size of the humidifier should match the size of the room where you plan to use it. A humidifier that is too small may not be able to raise the humidity level enough, while a humidifier that is too large may make the room too damp and promote mould and mildew growth. You can check the product specifications to see how much area the humidifier can cover, or use a hygrometer to measure the humidity level in your room.
- Runtime: The runtime of a humidifier refers to how long it can operate on a full tank of water. The longer the runtime, the less often you need to refill the tank, which can be convenient, especially at night. However, you should also consider the tank capacity and how easy it is to fill and clean. A large tank may last longer, but it may also be heavier and harder to handle.
- Features: Some humidifiers come with extra features that can enhance their functionality and convenience, such as:
- Humidistat: A humidistat is a sensor that monitors and regulates the humidity level in the room. It can automatically turn on or off the humidifier according to your desired setting, which can save energy and prevent over-humidification.
- Timer: A timer allows you to set a specific duration for the humidifier to run, which can be useful if you want it to turn off automatically after a certain time.
- Mist control: Mist control lets you adjust the amount and direction of mist output from the humidifier, which can help you customize your comfort level and avoid wetting nearby furniture or walls.
- Night light: A night light provides a soft glow that can create a soothing atmosphere for your baby’s sleep. Some night lights also have different colours or patterns that can entertain your baby.
- Aromatherapy: Aromatherapy is an option that allows you to add essential oils or fragrances to the water tank or a separate compartment of the humidifier, which can create a pleasant aroma and enhance your mood. However, you should be careful when using aromatherapy with babies, as some oils may not be suitable or safe for them.
