Best Tower Humidifier

The cold season is around the corner. As a result, everyone is busy shopping for heating systems or trying to get in touch with the HVAC technician to clean and perform regular maintenance on the central heating system. Hopefully, you haven’t forgotten about the need for an accompanying humidifier.

Although the biting cold is often the primary concern when the chilly weather sets in, the accompanying low humidity levels are just as much an issue. Low indoor humidity quickly causes dry skin, flaky skin, and inflamed nasal membranes. It’s also a recipe for allergic and asthma attacks.

A standard humidifier would help you avoid the trouble and keep your eyes, skin, and nasal membranes healthy throughout the cold season. And, if you’d like to add the humidity with some swagger, then a tower humidifier would be an excellent acquisition.

Below, we discuss more about these tower humidifiers and why you need humidification in the first place. We’ll also give a few tips on features to consider when shopping for a tower humidifier.

Buying Guide

Now, the buying process. What do you need to know about tower humidifiers, and what considerations should you prioritize when shopping for one? We’ll find out shortly.

Benefits of a Humidifier

Let’s begin with the reasons why you need a humidifier. Why not just brave the low humidity levels of the cold season? There are four key reasons;

  • Avoid cold and flu

Viral colds and flu are some of the first signs of overly dry indoor air. In the winter season, they tend to pass from one person to the next with no signs of slowing down and typically cause the affected person to feel awful. They may even interfere with your sleep.

Research shows that boosting the humidity levels to around 40% reduces influenza virus activity, effectively reducing the risk of flu to a mere 14%. By comparison, in humidity levels of around 22% (about the level you’d experience in the absence of a humidifier), about 75% of influenza are active.

  • Alleviate cold and flu symptoms

If the unfortunate event that you already have a cold or flu, the humidifier will still prove incredibly useful. Cold and flu typically come with stubborn but apparent symptoms. These may include pain in the muscles, cough with phlegm, a runny nose, sneezing, and post-nasal drip. You may also experience watery eyes, sinus pressure, throat irritation, and a slight headache.

We’ve already seen that improved indoor humidity alleviates congestion. Besides, it stops running nose and post-nasal drip. But there’s more. Easier breathing relieves sore throat, resolves headaches, and allows for more restful sleep.

  • Helps ease nasal congestion 

This comes as no surprise. Dry air causes mucus to become dry and thick. The result is usually clogged nasal passages that may leave you breathing with difficulty. If left unattended, the situation may worsen, resulting in a stuffy nose, sore throat, and sinus pain.

Humidifiers solve this problem by adding moisture to the air you breathe. As a result, your mucous membranes stay at the right humidity, with a significantly reduced risk of congestion or clogging. The additional moisture also helps break the phlegm in the nose and chest.

  • Prevent dry skin 

When the air around is too dry, it leeches moisture from our skins. It’s just how nature works. As it seeks balance, air will “suck” as much moisture from the surrounding environment (and objects) as possible. The reduced moisture levels can leave the skin chapped and flaky. What’s more, using lotions and chapstick may not be enough to rehydrate the skin.

The only solution to this problem is adding moisture to your indoors. Your skin will naturally absorb the moisture and slowly regain its previous supple state. Remember that dry skin can cause or worsen skin issues such as eczema. So, don’t wait too long to bring in a humidifier.  

  • Other health benefits 

Two other ways improved indoor humidification can enhance your health are keeping your hair and scalp healthy and helping with snoring and sleep apnea. Just like the rest of the skin, the scalp is significantly affected by dry air. This can cause an itchy scalp and dandruff. The hair may also become dry and brittle. Boosting indoor humidity levels can help a lot.

As for snoring and sleep apnea, humidifiers help to alleviate dry airways that cause snoring. Snoring, an itchy throat and the many cold and flu symptoms we discussed earlier can also disturb your sleep, resulting in apnea. Humidifiers address the issue by addressing the root causes.

  • Other benefits 

Finally, humidifiers can also benefit the rest of your home. First off, the increased humidity is critical for houseplants, if you have any. To survive and thrive, plants need water. Secondly, improved humidity is also vital for your pets.

Aside from the plants and pets, improved humidity also protects the wood items and surfaces in your home, reduces static electricity, and lowers heating costs, even if slightly.

Benefits of Tower Humidifiers

Tower humidifiers are large humidifiers that stand on the floor. The main distinction is that they don’t sit on the table or desk like the smaller humidifiers. Instead, they stand alone on the floor from where they pump moisture throughout the intended space. The following are four key reasons you should consider investing in one;

  • They are large-capacity humidifiers

This is one of the defining qualities of tower humidifiers. They are typically 4-liter tank humidifiers or larger, with some having capacities as high as six liters. This usually comes with one key benefit – longer running times. The humidifiers can run continuously for many hours, typically days. Many of them run for 50+ on a single refill.

  • Ideal for bigger spaces

Owing to their larger size, tower humidifiers are the perfect choice for larger spaces, such as living rooms and master bedrooms. Although the smaller humidifiers may suffice in some instances, you may need several of them in a large room with many people. You’d need to place the smaller humidifier very close to the bed in the bedroom to take maximum advantage of the added humidity in the bedroom. Tower humidifiers can serve more people, in larger rooms, even from several feet away.  

  • They are extremely portable

The smaller humidifiers are also very portable, maybe even more portable than tower humidifiers considering the size and weight difference. What gives tower humidifiers the edge is that they don’t need a special surface because they stand on the floor. As such, you can take the tower humidifier anywhere, even in rooms, such as the basement, where there may be no unique resting surface, and they’d work fantastically.

Cool vs. Warm Mist Humidifiers

Essentially, cool mist humidifiers emit cool moisture while warm mist models emit heated moisture. So, which is the better option? Which should you go for?

About cool mist humidifiers

Cool mist humidifiers disperse a cool stream of room-temperature mist throughout the surrounding environment. They are primarily available in two styles – evaporative and ultrasonic.

  1. Evaporative cool-mist humidifiers

These models use an internal wick to absorb water. A fan then blows air drawn from the room through the wick (which often also doubles as a filter). The process causes water to break down into fine mist particles, which are then dispersed into the room.

  1. Ultrasonic cool-mist humidifiers

These models depend on ultrasonic sound technology to break down water particles into a fine mist stream. The sound vibrations break down water into ultra-fine mist that’s quietly released throughout the surrounding air.


  • Safe for use around kids and pets
  • Can be used year-round
  • More energy efficient


  • Greater risk of bacterial growth
  • Fan technology makes them louder

About warm mist humidifiers

Warm mist humidifiers use a heating element to boil water and make steam. The steam is then released into the room/home. Since the steam is usually warm, these humidifiers add moisture and supplemental heat to the indoors.

Another critical advantage of warm mist humidifiers is that they are much healthier than their cool mist counterparts. Why? Because boiling the water helps kill any microorganisms. As a result, the moisture that comes into the room is cleaner and healthier.


  • Are a potential source of supplemental heat
  • Better for reducing bacteria and germs
  • Quieter than cool mist humidifiers


  • The heat/warm mist poses a burn hazard
  • The heating process consumes more energy

Tips for Using a Humidifier

The real work begins after you’ve purchased the humidifier. You’ll need to use it diligently and take good care of it if you’re going to get maximum value for your investment. The following are several tips to consider;

  • Install it in the right place

The humidifier should be placed on a piece of furniture at least two feet off the ground, except for tower models that don’t necessarily need to be two feet off the ground because of their height.

  • Place it far from the bed

The humidifier should be at least three feet from your bed. This is necessary to prevent over humidification of the area around you, minimize noise as you sleep, and protect you from burns (in the case of warm mist humidifiers).

  • Set it to the right humidity level

Though you’re free to choose the humidity level that best suits your needs, somewhere between 45% and 50% is the best setting. It minimizes chances of over or under-humidification.

  • Use the right water

Try as much as possible to avoid using tap water in your humidifier. Tap water contains minerals that can affect humidification in many ways. Instead, use distilled water. However, if you must use tap water, demineralize it first.

  • Change the water daily

Never let water sit in the humidifier for days. It creates a breeding ground for mold and bacteria. Instead, change the water every day. Make sure to rinse the tank with freshwater before refilling with new water.

  • Clean the tank regularly

Ideally, you want to clean your humidifier once every week. Switch it off, unplug it from the power outlet, and take it apart. Then use white vinegar to soak and clean the base and parts and bleach to soak and clean the tank. Soaking takes about 30 minutes. After cleaning them, rinse and leave to dry before reassembly.
