Things Need to Consider

Humidification Types

Modern humidifiers give you a lot of options to choose from. They provide different levels of humidification to you. Generally, they come as cool mist or warm mist humidifiers. Warm air humidifiers run hot and cold humidifier stay cool to provide cool air. The cool mist humidifiers come with no heating element in them and use wicking to disperse moisture into the air. These are the best humidifier for colds and works best for people suffering from conditions such as asthma.

The warm mist humidifiers are good for usage in areas where the water is soft. They work by heating the element which boils the water and disperse the water into the air by boiling it. These are particularly effective in killing all sorts of bacteria and are best use in aromatherapy.


All modifiers will provide good humidification if you live in a dry area. However, do take into consideration your environment. The place where you reside is a deciding factor in your experience. If you reside in a cold area, then a warm mist humidifier will work best for you. This not only lifts your room temperature and makes you feel comfortable but the warm vapor is also effective in relieving congestion and provides a soothing effect.

In more warm areas, you might want to use cold humidifiers. It will help reduce the temperature and give you the comfort you need.


Most of the new modifiers come packed with cool features. While all of those features might not come in handy. But there are quite a few of them that can be useful. Take for example the auto shut done feature, it is extremely useful when you can’t afford to fill the water reservoir every now and then. It can preserve the life of your humidifier. Some premium warm mist or cool mist humidifiers come with a humidistat which gives you the option to control the moisture levels.

There is also a pretty neat little feature known as the water tank indicator, this will give you prompt every time you need to refill the reservoir. Most of the humidifiers have a water indicator as well. So even if you don’t have those features you can still fill the reservoir on time.


Before buying, ask yourself what kind of capacity you need for the humidifier to service your room. All humidifiers have a defined coverage capacity. The normal range is normally up to 500 ft. But if you go for the premium models, you might be able to get double that range. Also do keep in mind the mist capacity the humidifier can produce. The higher the mist, the faster the unit will be able to do its job.

Ease of Cleaning

Humidifiers, especially the cold ones are more prone to overgrowth of bacteria. Also, there may be mold growing on the humidifier and that it the last thing you would want. When buying, do take into consideration how easy the humidifier is to maintain. The build of the humidifier also comes into play as there are some parts of the unit which are hard to reach and cant be cleaned.

Take for example the teardrop humidifiers all of which are good on looks, but can be difficult to clean. Do read reviews before buying one.


A humidifier can cost from anywhere between thirty to three hundred dollars. But you can increase your budget as much as you can. While deciding on your budget, do take into consideration the space that you want to cover, If you are buying just to cover your room, then the low-end units will do fine. But if you want something to humidify your whole house, then you might want to go up a level and invest some more to save you from future inconvenience.
