A good humidifier should do more than just add extra moisture to the air in your room as it should also make it better for your overall wellbeing. With the best Vicks humidifier, that is just what you get.

What makes Vicks humidifiers special is that besides humidifying the air, they will also diffuse their medicated vapor products to ensure the air in the house is useful for relieving coughs, colds, and sinus issues.

The Vicks brand has been around the 1890s, and they are more famous for their salve (VapoRub) for cold and cough relief. However, in recent years they have also ventured into the manufacturer of humidifiers.

In this piece, we look at some top-rated Vicks humidifiers and show you how to choose the best ones for your home.

What To Check Before Buying Vicks Humidifier?

1. Types of Mist

The type of mist that your Vicks humidifier will dispense matters a lot, and so as you pick one you will first need to decide the type of mist you want.

Here there are two main options, which are cool and warm mist.

– Cool Mist

Cools mist humidifiers will have a wick that soaks up the moisture and then a fan blows over it to circulate the moist air in the room.

These types do not have any heating element, and will hence be safer for use around kids, but they will not be useful for diffusing essential oils or medicated vapor.

– Warm Mist

The warm mist is what you will need if you want a humidifier that diffuse your essential oils and medicinal vapor.

These units will boil the water inside and release it into the air as steam. Vicks warm mist humidifiers will work with their liquid inhalants for added comfort and cough relief.

2. Coverage Area of Vicks Humidifier

It is important to make sure the Vicks humidifier you choose will provide enough coverage area for your room.

Here is the right type for you will depend on the specific room size that you will use the unit from.

The good news is that Vicks has small, medium, and large coverage models that will cater to the needs of all potential users.

Their small model like the Vicks VUL520P will cover up to 250 square feet, while the medium ones like Vicks V4600 can cover up to 400 square feet.

3. Water Tank Capacity of Vicks Humidifier

Big tank capacity is always more preferable as it will eliminate the need to keep refilling the humidifiers, which ensures convenient use. Most Vicks humidifiers will typically have a 0.5 to 3 gallons tank, and so there is something for everyone.

It is important to keep in mind that the larger the tank capacity then pricier the unit and the larger and bulkier it will be. Hence, you need to strike a balance between the capacity, cost, and size of the unit.

4. Runtime

Runtime is more dependent on the tank capacity of the humidifier because the larger the tank the longer the runtime that you get.

That said, different models will still use the water differently. Hence, models with the same tank capacity can still have different run times.

All in all, the best Vicks humidifier for you is one that will provide at least a 12 hours continuous run time as it means it will run the entire night without requiring a refill. But, something with an even longer run time like the Vicks V3900 that will run up to 30 hours will be more convenient.

5. Vicks Humidifier Noise Level

Because you will often leave your humidifier running as you sleep, you need to make sure that it will not be very loud as this can distract you or prevent you from sleeping.

Hence, the lower the noise level the better the humidifier will be as you can still sleep well even when it is running. Something with a noise rating of under 50 dBA should be quiet enough for most users.

6. Portability

Portability will hardly ever be an issue with Vicks humidifier as most are designed to be more compact and easy to carry around.

However, besides being small and portable, a good model should also include a nice carry handle like the Vicks V3900. A handle provides a comfortable and safe place to hold the appliance and hence making it even easier to move.

7. Maintenance

Maintaining your humidifier is vital to ensure it remains in good working condition. And so the model that you choose should make cleaning and maintenance easier.

To make sure that the humidifier will give you an easy time when it comes to the maintenance, look for something with a wide tank opening and an easy to wipe surface. Also, something with dishwasher-safe parts will be easy to clean and maintain.
