Best Humidifiers for Winter

A humidifier helps ease issues like nose bleeding, cracked skin, congestion, and allergy symptoms brought about by increased air dryness during the chilly winter months.

Of course, there are other helpful measures to raise the humidity in winter including boiling water on your stove and planting buckets of water around the house.

But as you might be aware, none of these can be as effective as humidifiers.

This article reviews some of the best humidifiers to fight dry air during the winter season and will also highlight useful tips to help you land the best.

Read on.

How humidifiers work

The devices ‘make’ and release colossal amounts of moist air into the room until humidity rises to safe levels (30-50% as per the EPA guidelines).

The machine creates the moisture through methods such as heating and high-frequency sound vibrations depending on the type of humidifier in use (more on the types shortly).

Some let you add essential oils and inhaler products to help your loved ones feel better.

Why invest in a humidifier

You see, humidity levels will always drop dramatically during the winter bringing lots of suffering for you and your dear ones.

Having the best humidifiers for winter on can make all the difference in such times – they elevate humidity levels to comfortable levels making your spaces feel warmer while improving your breathing, sleeping, and soothing ailments like nasal congestion.

Remember that dry air may cause other problems like static electricity, cracked paint, and might even destroy wooden furniture.

And as you very well know, the alternative hacks like growing natural humidifying plants (and the others I mentioned above) are a bit clumsy and only moderately effective.

Types of humidifiers

Different types of humidifiers exist- the key difference is the technology used to produce the moisture which is often released into the air as either warm or cool mist.

Here are the dominant types:

Evaporative humidifiers

These use a fan and a wick filter to create evaporation of the water leading to the emission of moisture into the air.

They self-regulate meaning they hardly over-humidify (too much humidification can help germs thrive indoors) and are quite resilient.

But they’ll need a higher maintenance budget since the filters need to be changed every few months.

Ultrasonic humidifier

Here you have high-frequency sound vibrations (they contain a vibrating diaphragm) helping to form and expel fine mist into the room.

The best humidifiers for winter units are extremely quiet but lack a mechanism to tackle mineral deposits (or “white dust”).

Steam humidifiers (Vaporizers)

These have a heating element to boil the water to produce steam that’s later passed into the air to help moisturize your room.

Steam effectively kills microorganisms and you can even add your favorite medicated inhalant but the heating process carries unique risks including the possibility of the unit overheating or starting a fire.

Impeller humidifiers

Rotating disc launch water at a built-in diffuser here. It will then break up the water until extra-fine water droplets emerge into the air.

These types of humidifiers also do the job but tend to escalate bacteria and mold growth if not cleaned regularly.

Their other downside is the lifted noise level.

Best Humidifiers for Winter Buying Guide

Keep in mind these issues when shopping for a humidifier to serve your needs:

Cool mist or warm mist?

Humidifiers spray two types of mist: warm or cool.

Now, both perform an amazing job.

However, humidifiers that release warm mist powerfully kill toxins like bacteria in the course of the heating process (they heat before evaporating the water) and could help bring healthier air.

Heating can, however, be counterproductive if you own pets or have young children- either of them can get burned when playing close to the warm mist unit.

On the other hand, cool mist humidifiers don’t apply heat during humidification – most are ultrasonic– and are subsequently preferred in rooms used by kids and pets.

But warm mist models can counter that the heating makes the rooms cozier when it’s freezing outside while the cool mist types may argue that cool air best rehydrates dry skin, nasal passages, and your respiratory system.

In short, the best mist depends on your personal needs.

Luckily, there are units that yield both cool and warm mist – this work all year round while bringing the best of both worlds.

Optimum room capacity

There are humidifiers designed for small, medium, large, and extra-large rooms.

Fortunately, the package indicates the square footage so this should be straightforward provided you have measured the room.

Maximum noise levels

Like air purifiers, humidifiers are not silent.

Needless to say, you want a winter humidifier that’s quiet enough to let you enjoy a more restful sleep.

Where do you live?

Warm mist humidifiers are more homely in colder environments since the warm vapor boosts the room temperature.

People with homes in warmer areas are better off with cool mist humidifiers- the cooling effect makes the room more relaxed and you might find it easier to sleep.

The tank

Units with bigger reservoirs last longer and you don’t need to come out of bed at midnight to refill it.

In addition, a transparent tank makes it easier for you to track water levels (opaque models with a low water-level indicator are fine too)

It’s also best for the tank to have a handle since it makes handling during refilling a breeze.

Larger tank openings are also desirable because they simplify the cleanup.

Other features

The following features contribute to convenience and ease of operation.

  • Aromatherapy provision– units that accept essential oils will help you enjoy a healthy dose of aromatherapy.
  • Intelligent auto-shutoff– protects the unit from destruction if water runs out.
  • Sleep mode– turns off the lights to help you fall asleep.
  • Humidity sensor– helps the unit automatically track and keep humidity comfortable.
  • Intuitive control panel– lets you set the required mist amount without struggling.
