Ultrasonic Humidifier Buyer’s Guide

There are the products, and there are some common features across the board that are applicable to a lot of humidifiers and are the main things that you should be looking for. Read on below to discover a more in-depth buyer’s guide for buying a humidifier for your home.

Ultrasonic Humidifier

There are several different types of humidifier on the market. This review has focused on ultrasonic humidifiers. Ultrasonic humidifiers form mist particles that are put back into the air through vibrations at ultrasonic speeds in the device itself. They mainly offer cool mist, but some models do offer warm mist as well. They do not generally have filters, so they are much less maintenance than other humidifiers, and they are generally easy to operate as well, very quiet and come in a variety of sizes.

Why do you need this Humidifier?

Humidifiers emit moisture into the air to make it less dry and more moist. Moister air is healthier for the lungs and the body and has numerous benefits. Household humidifiers are generally very easy to set up, come with handy features and functions, are very quiet and look subtle in their design as well. They have even been known to decrease snoring thanks to the ways they keep the nasal passages clearer in the night time. So, if you suffer from cracked or sore skin or congestion problems, then you may be looking to add a humidifier to your home.

What space do you have to Work With?

The size of your rooms will dictate which humidifier you should buy. Different humidifiers come with varying sizes of tank and are built in different ways to make them able to cope with different sized rooms and environments. You need to have a clear picture of the measurements of your desired humidifier destination room in order to match up the correct water tank size to your square feet of surface.

There are three Different Ranges of Humidifiers

Portable: As the name suggests, these are humidifiers that you can move around from room to room. They are generally smaller, with a small tank and a smaller capacity. Their price tag normally reflects this as well. Though they do require refilling more often, they are out of the way and don’t take up too much space.

Room Sized: These are less portable as they tend to be larger, bulkier as well as heavier than standard portable humidifiers. Of course, you can move these from room to room, but it will require a bit more effort.  They can handle a more significant room capacity, but you would need to make peace with the fact that they will be a feature in the room, as opposed to something you could tuck away on a shelf.

Whole House: These are the biggest version of humidifiers out there at the moment. They are noisier, and they also require more maintenance. They are also very much a significant presence in any room that they are placed in. Though, Whole House humidifiers have a large capacity and service a large area providing a good quality of air.

Where am I Putting this Humidifier?

You need to think seriously about which room you are wanting to put the humidifier in. For example, if this is a child’s bedroom, then you will need to look for a quiet model, maybe with LED night light functions as well. Then the humidifier becomes multipurpose, can be left on overnight without disturbing the child and performs its job as well. However, if sound is not an issue for you, then you don’t need to be as picky with your humidifier choices.

Generally, one advantage of ultrasonic humidifiers is that the ultrasonic action taken to create the mist that is produced from the humidifier itself is just that: Ultrasonic. Therefore, it operates on a level that human ears cannot register. It may be worth considering an alternate option if you have a pet, however, as they may suffer because of it.

The Maintenance

As mentioned above, ultrasonic humidifiers don’t tend to need a lot of maintenance. They generally filter free. However, you do still need to clean them. You especially need to keep them clean if you opt for a model where you can add aromatic oil. This usually is into a little tray that can be wiped clean or washed as a normal household object, i.e. in the sink with washing up liquid.

The tank will also need cleaning on a regular basis in order to ensure that there is no mildew, bacteria or (heaven forbid) mold build up in the device. If you don’t do this, then your humidifier will not go the distance.

Did you Know?

Humidifiers are actually used to improve the health of the body. They can prevent sore skin, lips, and eyes and avoid itchiness of the skin as well by pumping air back through your environment.

Expert Tip

Make sure that you have thoroughly researched the temperature of mist that the humidifier emits. You don’t want a constant stream of warm mist that you weren’t anticipating and vice versa!
