The Difference Between an Air Purifier and Humidifier

The main difference between an air purifier and a humidifier is their purpose.

These devices combine both in a single unit.

Should I Buy an Air Purifier and Humidifier


According to the CDC, in the US, 1 in every 12 people has asthma. Asthma is a health condition in which the bronchial tubes are inflamed.

When the asthmatic patient breathes in polluted air, their lungs experience difficulty breathing in. And although vacuuming your home removes some of these irritants, most are left floating in the air.

Air purifiers and humidifier combos are fitted with HEPA filters to filter all these pollutants all day long, drastically reducing the chances of an asthma attack.

Dry Air

Dry air can irritate several parts of the body. And that’s where an air purifier and humidifier combo comes in.

The humidifier adds moisture to the air. This extra moisture helps in treating nose, skin, throat, skin, and lips dryness. Additionally, it will help in alleviating flu symptoms.

Respiratory Infections

The air in our homes has numerous chemical and gas pollutants emitted by our home products. These substances lead to respiratory (cardiac and sometimes neurological) infections.

But the best air purifier and humidifier combos can remove even the tiniest of pollutants, including bacteria responsible for the most common respiratory infections.

Air Purifier and Humidifier Features to Consider

Humidifier Type

Humidifiers are classifiable as cool mist, warm mist, and ultrasonic. And the best type will, of course, depend on your individual needs and preferences.

Cool mist humidifiers lack a heating element and are best for use in areas with hard water areas and are best for people living with asthma.

On the other hand, warm mist humidifiers rely on a heating element that disperses hot vapor into the air. These are relatively quiet and are best for killing bacteria, spreading scents, or medicines.

Finally, we have the ultrasonic humidifiers. These types of humidifiers are super quiet and are best for use in bedrooms. They use vibrating sound waves to disperse moisture into the air.

Room Size & Coverage

Different air purifier and humidifier combos are rated for different room sizes and coverage. With that in mind, you must ensure that the combo you choose is ideal for your room size.

You can do this by measuring your room’s size and checking the recommended coverage of different air purifier and humidifier combos to see which one will work best for your needs.

Water Tank Capacity

The water tank capacity goes hand in hand with the coverage. That’s because the size of the water tank will determine how often it will need refilling.

If the tank is too small, you may need to refill it after every few hours, which may be inconvenient, especially for a bedroom air purifier and humidifier combo.

Also, ensure that the tank is easy to remove, refill, and fit. These are less messy.


The golden rule when buying any product is to ensure the product is built to last. And a sure way of determining which products will serve you the most is by looking at their warranty.

If a product has a generous warranty, that’s a sure sign that the manufacturer is confident in their product. Some will even offer 100% refunds in case you’re dissatisfied with your product.


Air purifier and humidifier combos are known to produce a significant amount of noise during their operation. That’s major because a single machine is doing the work of two.

However, different machines will produce different noise levels. Choose one with the listed amount of noise. But it may be challenging to determine the noise level of a device before testing.

Thus ensure you read as many reviews before your purchase to determine which one produces the least amount of noise.

Common Questions Relating to Air Purifier and Humidifier

Can You Use Humidifier and Air Purifier at The Same Time?

Yes. You can use an air purifier and humidifier at the same time. That’s because these two devices perform different roles. A humidifier adds moisture into a room, while an air purifier removes any pollutants and allergens present in the air.
Therefore, you can use the air purifier and a humidifier simultaneously, even in the same room.

Do Air Purifiers Make the Air Dry?

The science behind an air purifier’s performance doesn’t involve any mechanism of removing moisture from the air. Instead, the filters only capture unwanted chemical gases. Thus, an air purifier doesn’t make the air dry.

Do I Need an Air Purifier if I have AC?

An AC and an air purifier perform two completely different roles. An AC helps regulate the temperatures in a room while an air purifier removes pollutants in the air. AC doesn’t filter any allergens or contaminants in the air.

The Verdict

There you have it! You’re now armed with tips to choose the best air purifier and humidifier combos – to clean and purify the air in your room or office.

Admittedly, in the beginning, choosing the best combo for your needs might be a daunting process.

But regardless of your choice of air purifier and humidifier combo, remember to check its noise levels, coverage, type, and warranty.
