Do You Need An Air Purifier For A Baby Nursery?

by Josh M

Preparing for a nursery is an exciting time but also one that can be stressful and nerve-wracking. There are a number of questions that you may be asking; should I get an air purifier for my baby? Is an air purifier safe for babies? To help put your mind at ease, read on for all you need to know.

So the question remains: do you need an air purifier for the baby, and is this a crucial element of the nursery? Before answering this question, we took a closer look at what an air purifier is and how it works.

In the simplest terms, an air purifier is an appliance designed to filter out any potentially harmful chemicals, toxins, and pollutants from the air around your home, ensuring that the inhabitants breathe clean, fresh air.

Air purifiers come in three main types:

As the name suggests, filter air purifiers work by removing products such as pollutants and allergens directly from the air and do not produce byproducts.


An electronic air cleaner will add a static charge to particles, which encourages particles to stick to objects and fall from the air, allowing them to be removed. Not all particles and pollutants may be removed, and these types of purifiers produce ozone as a byproduct.

Ozone generating purifiers take this one step further and create ozone to clean the air chemically. There are claims that pollutants and particles are degraded by these types of purifiers, but scientific evidence of this is dubious.

When determining the answer to the question “is an air purifier good for babies?” we, therefore, need to consider the types of purifiers. Experts widely agree that filter air purifiers are the best option for a baby’s room or nursery, as there are no potentially harmful byproducts such as ozone. These are also generally considered to be the most efficient and effective options

Provided that the right appliance is chosen, an air purifier can be a huge benefit to your baby and offer advantages for your baby’s overall health and wellbeing.

Air purifiers remove any potentially dangerous pollutants or allergens from your baby’s room, which can help reduce the risk of allergies, asthma, and, in more extreme cases, long-term lung damage. If you choose an appliance that includes white noise, air purifiers can also be a great way to help your little one drift off to sleep, keeping them calm and relaxed to enjoy plenty of quality shut-eye.

Benefits Of An Air Purifier For Babies

  • Improved Health
    The smaller size of a baby’s lungs compared to adults means that breathing in toxins and pollutants can be a real issue, and air purifiers help to reduce this risk.
  • Help With Sleep
    In many cases, air purifiers can also help to improve the quality of your baby’s sleep, offering a “white noise” effect that can be very soothing and relaxing – perfect for nodding off and getting plenty of rest.
  • Reduce Smells
    One of the often overlooked benefits of air purifiers is that they can help to reduce unwanted smells and scents in the room. The right air purifier will remove any unwanted odors from the space and offer a fresh, clean feel and smell to your baby’s space.
  • Less Risk of Allergies
    Reducing the number of toxins and pollutants in the air can also help to reduce the risk that your baby will suffer from allergies and illnesses, and this is great for overall health and wellbeing.

Will An Air Purifier Help With Baby Congestion?

Another key advantage of air purifiers is that they can be very useful at reducing the congestion suffered by your baby. According to experts, HEPA filters can seriously improve the air quality in the room, which can help reduce exposure to pollutants and chemicals through filtration. [1]

It is worth noting that while experts are still in discussion about the benefits of air purifiers in terms of preventing external toxins, there does seem to be agreement that the presence of an air purifier in a single space, such as their bedroom or nursery, allows your little one to breathe cleaner air and boosts sleep quality.

Safe Use of Air Purifiers In Your Nursery

One of the most important elements in using an air purifier in the nursery is ensuring that your baby is safe, and a large factor in this is the placement of the air purifier. According to experts, air purifiers should be placed around 3 feet from the baby and the bed, reducing the risk of dampness and possible mold.

You should also make sure that the air purifier itself is in a safe place and that there are no wires or hazards that small hands may be able to grab – these units tend to be heavy and can be dangerous if they fall on or near your baby. The unit should ideally be located in the center of the room for the best results.

It should be safe to run your air purifier for the duration of the day and into the night – as we mentioned, this can help your baby to sleep – but it is crucial that you take time to clean the filters at least once a month. Remember that the job of the filter is to trap and catch potential harmful fibers and allergens, and so the last thing that you want is these hanging around in your home, potentially causing harm to you and your baby.

What Type Of Air Purifier Is NOT Safe For Babies?

When choosing an air purifier for your baby’s nursery, it is important to note that there are a few types of air purifiers that you should avoid. Ozone air purifiers should only be used when people and animals are not in the area. Ozone is irritating to both the eyes and skin and can cause particular problems for babies due to their more sensitive bodies.

This issue has also been reported with UV-C air purifiers, which are thought to also produce low levels of ozone. To help ensure that both you and your baby are safe, it is best to avoid air purifiers of this type.
