How to Buy a Humidifier – Ultimate Buying Guide

The amount of moisture in the air is known as humidity. If the level is not just right at between 25-40%, adverse effects will be suffered. Low humidity occurs in dry and hot desert climates as well as artificially heated rooms. It will cause exacerbation of allergies and destruction of art, furniture, and books. Higher than appropriate humidity will cause prevalence of dust mites and mold.

It is easy to tell whether the air is too humid if it feels dense and the curtains are slightly damp. However, to get exact measurements, a hygrometer comes in play. A humidifier is a device that releases moisture in the air. A humidifier can be a friend or foe depending on use and maintenance.

Important Questions


How big is the space you want to humidify? Are you looking to keep the whole house humid, a few rooms or just one room at a time? These questions will help you to know whether you should get a tabletop, console or a central humidifier.

Warm or cool?

Humidifiers can either be warm or cool mist. The ultrasonic comes with both settings. The warm mist humidifier boils the water before releasing it into the air as vapor or steam. For this reason, it has the advantage of killing germs that may have been breeding in the water. This type of humidifier is also less noisy as it does not need fans and fast rotating discs.

The cool mist humidifier uses discs to turn the water into mist, which it releases into the room. This kind does not run a huge electricity bill unlike the former. This humidifier can be placed in a room where children and toys run around freely without running the risk of burns. Whichever one you choose should be the best suited to your needs.

How much?

This is the significant point. It is okay to dream but always comes back to reality and consider what you can afford. There is something for everyone.

How often?

Will you use it every day? Will you only have it on every other day? For how long will it be on? This will determine the frequency at which the water will be replaced. If the humidifier is for everyday use, the water will need to be replaced at least twice a week. It will also require a good cleaning to keep it from becoming a breeding ground for bacteria. In this case, the best humidifier will be the one that is easiest to take apart. In this respect, you should consider the tank size and moisture output capacity of the humidifier.


Some humidifiers come with built-in humidistats, which monitor the level of humidity in the room. Once it gets too high, they shut off immediately. Instead of the budget, you can opt to get a separate a hygrometer. Either way, you need a way to measure the humidity in your home.


How will you know the water has been in there too long? How will you tell the filters to need to be replaced? How will you know it is time to clean it? Some humidifiers come with indicators that notify the user of their needs. Therefore, if you are the kind to forget when to do the above, this should be a point of consideration.

Once You Have Your Humidifier

Manual is not decorative

Always read the manual. The manual holds information that could be the difference between allergy flare-ups and a comfortable appropriately humid home. In the manual, are care instructions and operation directions.

Keep It Clean

The humidifier will not stay clean just because it holds water. If the water sits in there for too long, a film forms on the surface on which bacteria breeds and seeps into the air you breathe. The manual will often advise you to clean the humidifier with hydrogen peroxide and bleach. This is especially important in the fight against bacteria. Cleaning should depend on the frequency of use.

Tap water

Unrefined tap water causes white mineral dust to settle in the air. This, if breathed in over a period, is incredibly harmful. To solve this problem, either use distilled or purified water or get a demineralization cartridge integrated into the humidifier. That is if it is not pre-installed.


The console and tabletop humidifiers need to be correctly placed for maximum benefit. Tale tops need to be on raised surfaces. Both types should be at least 12 inches away from the wall. Books and other items capable of absorbing moisture should be kept away from humidifiers, so they do not get damp.
Some nitty gritty to think about are adjustable speeds, UV Germicidal lights to kill germs in the mist before releasing and air cleaning pre-filter to clean the inbound air.
