Air Purifier vs Humidifier For Baby: Which is better?

Looking to get a device to improve air quality around your baby?

An air purifier or a humidifier both are great options but take care of very different air quality issues. So, in the humidifier vs air purifier for baby debate which one comes on top?

An air purifier for a baby can remove particulate matter from the air while a humidifier for a baby will add water into the air to combat dry air conditions. Air with the right amount of moisture will help your baby breathe comfortably while the cleaner air from an air purifier reduces the chances of inhaling lung irritants.

So, which one is better?

Both these methods can improve the air quality considerably but for your convenience, we’ll discuss the benefits of each device in detail and how they can improve the air for a baby.

Air Purifier Vs Air Humidifier – What’s The Difference

Air purifiers use the power of mechanical filtration (HEPA filter) to remove airborne contaminants and might feature multiple filters to remove different types of contaminants. An air humidifier is simpler in operation as it converts water into vapor and releases it into the indoor air to restore the moisture/humidity levels.

Air humidifiers cannot remove pet dander and other particulate air pollutants from the surrounding air but the fine mist can help your baby feel better.

Air purifiers do remove allergens and contaminants like dust particles and some air purifiers also bring activated carbon filters that can help keep volatile organic compounds and odors away (and also those pesky diaper smells).

Here’s a table that shows how your baby’s room can benefit from each of these devices and might clear some misconceptions when it comes to air purifier vs humidifier for baby.

How can a humidifier help with my baby’s health?

If you’re looking to buy an air humidifier to help your baby’s congestion, a warm mist humidifier will actually make it worse. This is because it causes dilation of vessels in the nasal passages constricting the airflow.

Be sure to opt for a cool water vapor humidifier if you’re looking to fight off persistent colds as it can constrict the blood vessels in the airways and improve the baby’s health.

Humidifiers can also make microbes and pollutants less mobile leading to a reduced chance of allergy flare-up.

Air Purifier Vs Air Humidifier – The Similarities

While there may be similarities in the physical appearance of an air purifier and humidifier the operations are quite different. Interestingly enough for the consumer, both an air purifier and a humidifier can produce comparable differences in air quality.

Similar changes in air quality are due to the nature of the contaminants. The added moisture content from humidifiers can slow down the movement of microbes and other such pollutants and can cause them to stick to certain surfaces.

The right humidity levels can help your baby breathe better and more comfortably and the indoor air will feel fresher even if for a short period of time.

An air purifier also produces a similar sensation of fresh,  breathable air and significantly reduces congestion, but the removal of contaminants is permanent until polluted air from the outdoors is allowed to flow in.

Air Purifier Or Humidifier For Baby – Which One Do I Need?

If you live in a spotlessly clean region that doesn’t have any apparent contaminant like dust mites or pet dander, but the air is cold, you probably don’t need a purifier. Cold air is very dry and can cause a stuffy nose and cause skin cracks.

This dryness can be even more problematic for babies as the baby’s immune system is not fully developed and can lead to aggravation of certain conditions like asthma while also causing dry skin among other issues.

On the other hand, if moisture is plentiful in your surrounding air and you’re not using any active heating to warm up the air indoors then you don’t need a humidifier for your baby. Air purifiers are best for such places if the AQI in your region is bad and you want to provide your baby with safe air to breathe in.

These conditions are hypothetical and don’t translate to real-life conditions as you might need both the devices in most regions. You can consult this detailed guide on both these devices and their functioning.
