The best humidifiers

Whether you live in very dry or very humid areas, the humidity of the environment is not always adequate. We may notice a certain dryness in our skin or throat even if it is raining outside, due to the dryness caused by the environment and heating, for example.

If this is the case, the best option is to get a device that helps regulate the humidity of the environment: a humidifier. We tested a selection of humidifiers for several weeks and have decided that our favorite is the Honeywell because it’s quiet, easy to clean, with 1-gallon tank that lasts all day.

Setting the humidity levels in your home between 40-60% can help you breath better, sleep more comfortable, reduce nasal congestion and dry skin. Using a humidifier reduces static electricity, damage wooden furniture, and irritate health issues.

Why Trust Most Dear?

With more than 3 years of expertise covering home appliances large and small, Cristian Gonzalez has an eye for the features and benefits of essential home devices like humidifiers. He learned firsthand the importance of a humidifier while living in Madrid, a dry and polluted city combined with his allergies makes this machines essential at home.

Why are humidifiers good?

Humidifiers are devices designed to adjust the humidity of the environment in closed spaces by transforming water into steam.

In summer, high temperatures reduce humidity and environments become drier. In winter, heating devices replace summer temperatures. Both of these factors cause the relative humidity of the environment to drop, so the ideal is to measure it in order to correct it.

Why is it important to maintain the correct humidity in the room?

Especially for older people and babies, it is recommended to keep the humidity of the environment between 40 and 60%. If we notice that our lips are dry and cracked, that our throat is dry, that our eyes are irritated and lack moisture, dry skin, or we feel nasal and breathing difficulties; it is possible that the humidity of the environment is not adequate.

A humidifier is not only beneficial for people, but also for plants and animals.

What to consider before buying a humidifier

We already know that a humidifier is designed to provide humidity to the environment from water vapor. But not all humidifiers work in the same way.

Hot steam humidifiers or boiling humidifiers. They heat the water inside, causing it to escape into the environment in the form of steam.

They are not considered ideal, because the steam comes out at boiling temperature generating hot steam, which increases the temperature of the environment and in case of accidents can cause burns.

However, they are highly recommended for nasal or respiratory congestion, since the steam combined with the heat helps to soften mucus.

If the water is very hard, it contains many salts that increase the electrical conductivity causing it to boil faster. As a result, the amount of steam that will be released into the environment will be much greater, perhaps resulting in excessive steam.

Cool steam humidifiers expel water vapor in two different ways:

  • Evaporative, which work by circulating air through a hot wet wick filter. The disadvantage is that they usually use distilled water, otherwise the wick can become clogged.
  • Ultrasonic, which expel air vapor by means of high-frequency vibrations. The water is hit by ultrasound and comes out in the form of steam, which will have the same temperature as the water we have placed. Some models incorporate a negative ionization system to purify the air, because the negative ions neutralize the polluting particles in the air. They are the most common because they are the quietest.

In general, they are very small units that can be placed on any piece of furniture. They do not require any type of prior installation. It is enough to connect them to the electric current and their consumption is around 35W.

The water tank usually contains between 1 to 6 liters. The size of the environment and the autonomy of operation of the humidifier will be conditioned by the size of the tank.

If we keep them clean and change the water periodically, we will avoid clogging and proliferation of bacteria in the water; especially in cold steam humidifiers, which do not have the possibility to boil the water and eliminate them like hot steam humidifiers.

The humidification or misting capacity is the capacity of the humidifier to produce water vapor. In general, for a surface of 30 m2, about 200ml/h of water vapor will be needed to achieve an ideal room humidity. If we can count on a hygrometer (used to measure air humidity) much better because it will allow us to control the humidity of the environment and avoid raising it above optimum levels.

We must place them in areas that allow the humidity to be distributed evenly. To do this we must avoid corners, very high or very low furniture, close to mirrors or curtains because they can stain them with steam.

If the humidifier comes with air filters, we must take into account the frequency of replacement, that it is easy to obtain them, that they are easy to replace and that their price is reasonable. In general, the use of distilled water, previously boiled or filtered, is recommended.

As additional features, most of them allow you to set the number of hours you want the humidifier to be producing steam. Some also allow you to regulate the steam intensity or even include a hygrometer and adjust the steam according to the humidity of the environment automatically.

Filter vs filter-free humidifiers

  • Filter pros:
    • Removes allergens and bacteria from the air
    • Better for people with allergies or respiratory issues
    • Less white dust
  • Filter cons:
    • Costly
  • Filter free pros:
    • Avoid filter maintenance
    • Affordable
  • Filter-free cons:
    • Harder to maintain
    • More bacteria in the air
