Air Purifier vs Humidifier

Humidifiers and air purifiers can both make a big difference in the air quality of your home. The suitable machine will help you breathe easier while also improving respiratory symptoms or dry conditions like asthma – but they each have their unique purpose! You might wonder how air purifiers and humidifiers affect your quality of life. You also may not know precisely what they do or the differences between them, so in this article, we explore those questions with helpful information on where you can find one that’s right for you!

Air Purifier

Though there are many different air purifiers, they all work similarly. Air is sucked into an inner section where it’s cleaned by removing or “inactivating” pollutants from inside that space, giving you a better indoor air quality – this includes both physical particles like dust, pet dander, and dirt as well chemicals such gases which can cause problems for your health when inhaled over long periods.

Most commercial filter-based air purifiers have a high-efficiency particulate (HEPA) filter. These are built from mesh threads made of plastic and fiberglass, which stop contaminants from creeping through, including irritants or allergens such as dust, bacteria, mold etc. Still, they don’t remove viruses altogether, so if you want complete peace of mind regarding your health, we recommend looking into other types too!


Humidifiers work by adding moisture and cool mist to the air in a room. They do this through an inner chamber that draws water from below and lets it flow out as water vapor, which then rises into your surroundings! There are many different ways humidifier systems can operate – some use boiling technology while others might vibrate ultrasonic waves across droplets of liquid for even distribution throughout their area; however, they all have one thing correlation: increasing relative humidity levels so we feel better when the environment feels dryer than usual.

Humidity is an essential factor for the health of people with respiratory issues. The higher humidity, typically between 30%-50%, can help relieve symptoms in those who suffer from asthma or allergies by clearing their airways since it will dilate them more quickly than dryness would shrink recovered size during inhaling exercises.

Air purifier vs humidifier: The Main Differences

The two devices work in very different ways to improve indoor air quality. You must first know your needs to understand which type is best for you.


Humidifiers and air purifiers work in different ways. For example, a humidifier helps you feel better by adding moisture to the air. At the same time, an Air Purifier will remove any harmful particles from it that could make someone sick or cause them discomfort, like smoke inhalation for those with respiratory problems such as asthma which might arise due to allergies.

For Allergen Levels

The air purifier helps reduce allergens and eliminates them with the advanced Molekule technology. A HEPA filter traps particles such as pet dander and dust mites, which is excellent for reducing the permeability of your home’s walls and ceilings since they’ll be able to breathe easier when it comes to their allergies.

Humidifiers are often used to help ease the symptoms of allergies and cold symptoms, but they can make matters worse because higher humidity increases dust mite survival rates.

For Asthma Symptoms

Both an air purifier and a humidifier do something for your asthma symptoms. Using an air humidifier can ease asthma symptoms if dry air is also a problem, but it does not affect the actual condition of being asthmatic.

People with asthma often find that their condition improves when they live in a home with an air purifier. This is because the filters on air purifiers can remove many harmful particles and chemicals, including those which trigger attacks such as dust mites and pet dander by causing irritations or blocking airflow into our lungs!

For Households with Babies

Humidifiers may be better in the nursery if you have dry air problems. Small children often need humid environments because it helps their respiratory system and makes them feel happier, so using one there will benefit everyone! You can also prevent scratchy throats from occurring by adding moisture into your home’s atmosphere.

Air purifiers can be a better choice for your baby’s nursery all year round. They reduce the number of harmful pollutants in the air, including potential toxins from tobacco smoke and other possible respiratory irritants like mold spores or pet dander to pollen.

For Dry Skin Conditions

The perfect solution to dry skin is a humidifier. Humidity will help rehydrate your cells and soothe the irritation that can lead from the pesky dry air, leaving you feeling refreshed all over again.

Maintenance Needs

The filters in an air purifier must be changed regularly every 6-12 months, or they will not work either. In particular, HEPA (high-efficiency particulate agricultural) filters are washable and can go through cold water cleaning if needed; however, it is always best practice before doing this that you consult your device’s manual for guidance on how often these types of replacements should happen.

Humidifiers should be cleaned at least every few days to avoid the build-up of minerals inside them. Tap water contains high mineral content, which solidifies when discharged off as white dust – this is an unhealthy irritant, so it’s better to use distilled water.


Humidifiers and air purifiers are both important for the quality of your indoor air, but it’s easy to see why a humidifier would be more costly than an air purifier. It’s important to be mindful of the continuous cost when purchasing an air purifier. The filter needs replacing every month or so, and this can quickly add up in price.

Can I Use Both an Air Purifier and Humidifier?

Because they do completely different things, an air purifier and humidifier can be used together in a single room. However, it is important not to place them too close together because this could cause problems with the moisture from your filter or otherwise limit how effective either device works for you!
