Are Humidifiers Good for Cars? Why Use a Car Air Humidifier?

Humidifiers are an excellent ally when fighting against health issues that arise from the low humidity levels of the air in the living or working environment. If you already use one in your home or at the office, why not invest in a car humidifier, to reap the benefits when you are on the road as well.

If you have been thinking about buying a humidifier for your car, but are not sure what are the benefits and what is the best type of humidifier for your needs, this guide will help you discover everything you need to know in order to make an informed purchase.

Benefits of a Car Humidifier

If you are already familiar with humidifiers, you probably know that the air in your vehicle can get very dry, especially when using the heating and ventilation systems. For those dealing with rosacea and sensitive skin, dry mouth, respiratory system issues and even seasonal allergies, all that dry air can cause flareups, irritate the eyes and the skin, and aggravate respiratory symptoms.

There are multiple benefits of using a humidifier in your car. It regulates the humidity levels in your vehicle and thus helps relieve allergy symptoms, helps with dry skin, rosacea and other skin irritations, and it also makes the air seem cooler or warmer, depending on the type of humidifier you choose for your car.

What Is the Use of a Car Humidifier?

If you have been wondering for a while now if a humidifier is good for your car?  The main purpose of a humidifier is that of regulating the humidity levels, which can sometimes drop significantly, especially when using the heating and ventilation systems of your vehicle to adjust the temperature, both during winter and the summer.

When Should You Use a Humidifier in Your Car?

Moisture levels should remain between 30 and 50% for a comfortable environment, so if you measure the humidity with a hygrometer and it drops below those levels, you should definitely get a humidifier for your car, since it emits vapours and counteracts the negative effects that occur when the air is too dry. Make sure you do not overdo it, though. Monitor the humidity levels and stop the humidifier when they exceed 50%.

What Type of Humidifier Is Best for Your Car?

If you have done a little bit of research on this topic, you probably ended up confused, with so many options available on the market, from evaporative humidifiers to impeller and ultrasonic humidifiers and essential oil diffusers. There is also a choice to be made between warm mist humidifiers and cool mist humidifiers.

If you want to benefit from other functions besides adding moisture to the air in your car, you could invest in a humidifier that also offers aromatherapy and air purification settings.

There is also a variety of sizes to choose from when it comes to car humidifiers. While motorized models are on the more expensive side, small hand-held models, that are battery operated, are cheaper and can be taken with you whenever and wherever you need them.

A portable mini car humidifier is all you need to change the microenvironment from a dry and irritating one to a soothing atmosphere with optimal humidity levels that helps you get rid of dry eyes, skin and mouth, clogged sinuses, cracked lips, allergy flareups and many more. Humidifiers that diffuse essential oils can double as air fresheners and are immensely helpful when you have a cold, and you must deal with sinus pain on top of not being able to breathe properly.

Small and lightweight humidifiers are convenient if you travel a lot. They usually run on USB or AC power and are quite easy to use and refill.

If you do not want to keep an eye on your humidifier all the time, to change its settings, you can opt for a car humidifier that automatically adjusts the humidity levels in your vehicle. This is helpful when using the heating and ventilation systems, since tuning them on and off can change the humidity levels quite often.

When choosing a car humidifier, you should also check how long does the humidifier last until you must fill it again. To avoid the inconvenient situation where the humidifier runs out of water when you are on the road, you should pick a humidifier for your car based on the dimensions of the water tank, the outlet type, how long can it operate for and, most importantly, you should check if it has an auto-shutoff feature.

Other elements that are good to have in a car humidifier are a water-level indicator, a timer, and adjustable spraying modes. If possible, it would be recommended to choose a car humidifier that also uses water bottles instead of a water tank. This is a more convenient option for those who travel a lot.

Other Things You Should Know About Car Humidifiers

There are many features or car humidifiers that you should know about, so you can make the best decision for your needs.

Nightlights are a great feature if you enjoy chromatic lighting. Car humidifiers with coloured LEDs let you select one according to your mood. Some models have up to eight colours to choose from.

Charging Ports are an essential feature to look for in a car humidifier since you might end up not being able to charge your phone and use the humidifier at the same time if the latter can only function with a 12-volt DC socket. While some car humidifiers come with one USB port, others offer two-amp USB ports besides the usual 12-volt DC socket.

If the car humidifier comes equipped with a fan, you can easily direct the mist in the preferred direction. This feature is a must if you want to have better control of the air circulation throughout your car.

Car humidifiers that double as oil diffusers are a pleasant addition to your vehicle, as they replace traditional air fresheners and can be used for aromatherapy sessions when you are on the road and need a quick refresh or a moment of relaxation while driving.

Please Note: Just because a humidifier is marked, for example “Baby Room”, it will still work for other things, for example “Living Room” or “Plant Humidifier”
