What to Consider When Buying the Best Humidifier
As with any product, there are many factors to consider when selecting the best humidifier for you. Here are some of the factors we consider most important.
How Much Does A Humidifier Cost?
Humidifiers are a product with a wide price range. You can easily find a humidifier for as low as $20, but there are also some that cost hundreds of dollars. There are good options in every price range, but keep in mind the cheapest options might be lacking some useful features and the most expensive options might do more than you need.
For a humidifier that is effective, easy-to-use, and has useful features, expect to pay around $40 to $80.
Ease of Use
Everyone has different standards when it comes to what is “easy,” so it’s important to get a full picture of how to use a humidifier before purchasing — especially the difficulty of the required maintenance.
Some things to consider include:
- How you will fill up the humidifier. Is it top-fill? Do you need to pour water in with a cup or pitcher, or can you fill the tank in the sink? Is the opening of the tank wide or narrow?
- Turning the humidifier on and off. Is the functionality of how to turn the humidifier on and off, or to change between settings, intuitive to you? Can you create your own settings?
- Routine maintenance. How do you clean the humidifier? Are any parts dishwasher-safe? Do you need to replace a filter or other accessory component? Is the level of maintenance required something you are willing to commit to?
Additional Humidifier Features
Many humidifiers, including the ones on this list, have additional features beyond the basics of simply humidifying. Here are some common features you may want to consider whether you want or not:
- Nightlights. Many humidifiers have a nightlight feature — some are automatic, some can be turned on and off. If you are easily bothered by light, you should check if there is a nightlight and whether it can be turned off.
- Doubling as a diffuser. Some humidifiers also function as essential oil diffusers. If you want the capability of adding essential oils for scent or aromatherapy, ensure your humidifier is designed for this use.
- Directional mist outlets. Many humidifiers allow you to control the direction the mist flows with a directional mist outlet, but not all do.
Most humidifiers are designed to be used in a room of a certain size. Some manufacturers will detail the square footage a humidifier can cover, while others will just indicate whether it is for use in “small,” “medium,” or “large” rooms. It is possible to over-humidify your bedroom, so it’s a good idea to pick a humidifier designed for your room size.
Additionally, the physical size of the humidifier is important. If you have limited space in your bedroom, you may want to opt for a smaller humidifier that won’t take up as much space.
Type of Humidifier
There are three main types of humidifiers to know about when shopping for your own: warm mist, evaporative, and ultrasonic.
- Warm mist humidifiers produce steam by boiling the water, changing it from a liquid to a gas. This allows the warm mist to permeate the air and increase the humidity. Warm mist can work more quickly to humidify the room, can warm up your room, and has the added bonus of the water boiling — and thus purifying — before it is emitted. However, they could pose a safety concern for children and pets.
- Evaporative humidifiers emit cool mist, working by speeding up the process of natural evaporation. They use a fan to blow air through a damp filter, which causes the water to evaporate into water vapor. That water vapor is then blown or otherwise emitted into the room to increase the humidity level.
- Ultrasonic humidifiers also use cool mist. They use high-frequency sound vibrations or a nebulizer to break the water into droplets, which are then propelled into the air by a fan or other mechanism. These humidifiers generally do not require a filter.
