A humidifier with UV light will improve your air quality by making sure there are no bacteria in the mist it emits. UV light is the one responsible for removing all the bacteria, viruses, or fungus in the water, ensuring a healthy environment.

If you suffer from breathing conditions or you’re dealing with a cold, you need a humidifier with UV light because it makes sure to keep the air healthy. Before the mist is released into the air, the UV rays will work to eliminate all germs.

Moreover, if you have hard water and worry about inhaling potential contaminants through the mist, UV light can help. It will keep the water clean and your surroundings safe and healthy.

UV light can also kill and prevent mold spores – which means that you will have less cleaning to deal with.

Features to Look for in the Best Humidifier with UV Light

A man inspecting a humidifier with UV light

If you want to get the best humidifier with UV light, then you must know what features to look for in one. Here are the most important ones:

  • UV-C Technology Details

When you find a unit that looks promising, you should look at the UV-C technology details. What does the manufacturer say about the technology? How much of the bacteria is it able to kill? It’s important to know this since having a clean mist is crucial for your air quality and health.

  • Effectiveness of Sanitization

How good is the device at sanitizing the room? Is the UV light option effective enough? It may be difficult to find this out without trying the unit, but make sure to check the reviews as people often bring up these aspects.

  • Speed Settings

Speed options will make sure you have a personalized experience with your humidifier, so it’s important to look for a unit with multiple speed settings. The device should be able to work on low or high, so you can pick whichever you want when humidifying the environment.

  • Noise Level

Nobody likes a noisy humidifier, so you have to make sure your unit can operate quietly. In general, the noise level will be specified in the features section, so look for it and find out if the unit is quiet or not. It’s best to go for something that you can use during the night too.

  • Additional Sanitization Systems

If the humidifier has multiple sanitization systems, that’s even better. Aside from the UV light feature, look whether it has filters or not. Filters will clean the water before it exits the unit, getting rid of contaminants, and making it healthier.

  • Can UV light humidifiers prevent the spread of viruses?

Yes, it can. UV light is responsible for killing bacteria and viruses from the mist the humidifier emits, leading to much healthier air.

  • Can I put tap water in a UV light humidifier?

Ultrasonic humidifiers can send water droplets into the air through the use of vibrations. Meanwhile, ultraviolet ones will use UV light to sanitize water before turning it into a mist. The easiest to clean humidifier is all you need if you don’t want “a mold-making machine.”

  • What do I do if my UV humidifier stops working?

If the unit stops working, try to contact the customer service, especially if you have a warranty in place.

  • Does my UV humidifier support aromatherapy or essential oils?

Some UV humidifiers support aromatherapy or essential oils. If you want this, you have to look for a device that has a designated tray for the oils.

  • Where do I put a UV humidifier?

You can put a humidifier on a safe surface where it won’t be tipped over. It can be a desk, a table, a nightstand, or just any straight surface from where it can reach all corners of the room.
