Air purifiers and humidifiers do not have clashing functions. So, they can easily be used simultaneously without disrupting each other’s performance.

Both an air purifier and a humidifier enhance the air quality. However, they perform this function in separate ways.

In a nutshell, a humidifier is concerned with the humidity levels. Whereas, an air purifier is used to improve air quality. But let’s understand this in detail.

Air purifiers act as air filters. Their job is to cleanse the air of any dust mites, smoke particles, or air pollution in general. However, their filtration system is not designed to filter out moisture from the air.

An air purifier will provide you with clean air and even prevent problems of the respiratory tract, such as lung cancer. But it will not cause dry air. What’s more, air purifiers with UV technology such as UV light are also known to kill harmful bacteria and viruses.

On the other hand, a humidifier adds moisture to your home to improve indoor air quality without bringing harmful contaminants into it. Humidifiers are especially useful for health-related problems such as preventing itchy skin and reducing nasal irritation caused by dry air.

Using these devices simultaneously is beneficial. You may need the humidifier to add moisture to fight the dryness while the air purifier filter works to remove pollutants. Undoubtedly, their combined air freshening capabilities are unmatched.

When Can You Use Air Purifiers And Air Humidifiers Together?

You can use an air humidifier and air purifier together any time you want. Or not at all. However, some people might be wondering, will I ever even feel the need to use them together?

Humidifiers add moisture to the atmosphere while purifiers filter the air of foreign particles. So, there are certain seasons when the combined power of both an air purifier and humidifier may be just what you need!

For instance, allergy season is an actual thing. However, as the air purifier works to remove pollen and pollutants from the air and the humidifier produces moist air to avoid dryness, your indoor air quality will improve greatly! With that, you can say bye-bye to your allergies too!

Further, the winter season brings cold air and dryness. Dry winter air is known to cause dry skin, chapped lips sore throat, nasal irritation, and whatnot! Plus, winter air can also be pollutant-laden which is a bigger disaster for indoor air quality.

However, with a humidifier and air purifier, both these issues and other symptoms can go away with a snap of the fingers!

More importantly, with viruses like Covid-19 causing pandemics, air purifiers with hepa filter, and humidifiers are essential technologies. Air purifiers with hepa filters are known to capture virus particles. Similarly, humidifiers can also slow down virus transmission by increasing humidity levels in the air.

Clearly, there are a number of reasons why you may want to use these devices simultaneously. Again, you might not need this combo. However, there is no harm in wanting your air clean and moist at the same space in time!

Things To Keep In Mind When Using Air Purifiers And Humidifiers Together

While there’s no risk in using an air humidifier and air purifier together at all. However, it’s still important to keep a check on your devices and ensure they are functioning properly.

Keeping the devices well-maintained is important for their optimal functioning. Without a proper check and balance, these devices can do more bad than good to your home environment.

So, if you want the air in your home moist with water vapor as well as pure, here are some things you should consider.

Humidifier Cleaning:

Taking care of the humidifier is necessary to prevent air contamination. For one, using distilled water instead of tap water is better for improving indoor air quality. It prevents the infusion of minerals into your air.

A daily cleaning routine for the humidifier is essential. An unclean humidifier can potentially add more mold spores and other dirt particles to the air.

Although the air purifier will cleanse the air of these small particles. A humidifier polluting the air defeats the purpose of the two devices working together.

Placement Of The Devices:

In order for these devices to work effectively, you should place the air humidifier and air purifier apart from each other. This way, the water droplets creating moisture in the home air purifiers will not interfere with the purification process of the air purifier.

When it comes to placement, humidifiers, either warm mist or cool mist, have compact designs. They will fit anywhere. Air purifiers, on the other hand, are much bigger. So you’ll need to carefully place them.

The bottom line is, the further away they are from each other, the better they will function.

Humidity Level:

Moisture in the air is great, but nothing in abundance is good.

So, keep your humidity levels regulated. The Environmental Protection Agency (EPA) deems 30% to 60% moisture as ideal humidity levels in a house.

Although you may want to keep your humidity levels around 50% or below during summers. This will prevent the moisture from interfering with the activated carbon filters used in the air purifier and causing bacterial growth.

Similarly, to prevent bacterial growth in the winter season, do not exceed the relative humidity level beyond 60%.

The Appropriate Timing:

When should you have these two air-enhancing devices together in the same room?

The winter air does not have enough moisture and can also carry dirt and pollutant. So, that is one season the two devices together in the same room or home will be good.

Next, allergy season that brings pollen, pet dander, and other such irritants can be a health hazard for sensitive people. Many experience difficulty breathing in the irritant-dense air. So, this is when you don’t want to choose between either an air purifier or a humidifier.

You want both!


As a final point, can you use an air purifier and humidifier together? Yes, a thousand times yes! In fact, there are new models called air purifiers humidifiers which combine the separate functions of the two together.

These devices feature a fancy digital screen which makes it easy and efficient to operate them. Plus, their energy consumption is more efficient than using two devices separately.

In any case, the bottom line is that keeping the air inside your home clean and moist is important.

The air indoors can be packed with volatile organic compounds, viruses, and dirt particles that can cause health concerns and allergic reactions. In addition, dryness in the air can cause dry skin, sore throat, mucous membranes (e.g. eyes and nose), and other problems. These problems could significantly increase your medical bills!

However, as air purifiers filter the air in your home while humidifiers use cold or warm mist to add moisture to it simultaneously, you can have the best air quality and prevent many health problems!

We say, don’t go choosing between either an air purifier or a humidifier when air purifiers humidifiers combo is the new big deal!
