Signs You Need a Humidifier

Humidity is all about how much water vapor exists in the air. Indoors, at home or at work, you will find a percentage expressing the relative humidity. The recommended value for a comfortable environment ranges between 30-50%. Lower humidity (under 30%) can feel uncomfortably dry. On the other hand, more than 50% humidity can make the space too friendly for bacteria and mold to grow.

Do keep in mind that a humidifier won’t make your problems magically disappear. But you can be sure that using one will increase the level of comfort in your home or office. So, how can you know the air is too dry?

To measure the level of humidity in a room, you can use a device called hygrometer. They are easy to find in most hardware stores. But if you aren’t convinced about buying one, check out some signs that indicate the humidity level is not ideal.

A sign can be the static electricity affecting your hair or your clothes. Also, count in the sparks that fly around at the slightest touch in winter. If you notice you have dry skin, that your eyes often feel itchy, that means the room needs more moisture in the air. A more serious and unpleasant sign can be having irritated nasal passages. A bloody nose or an itchy throat with unproductive cough can worsen the symptoms of a common cold. Also, if you suffer from a respiratory problem, dry air can only make it harder to breathe properly.

The Science Behind Steam Humidifiers

If you plan to invest in a humidifier for your home, you already know what is out there on the market. There are several types available, from central humidifiers to ultrasonic or impeller vaporizers. All these devices balance the humidity level in your home, so they can have a good influence on your health. What makes the difference between them is the way they add moisture to the air. Most humidifiers work by producing mist from cold water. Impellers have a rotating disc that flings water at a diffuser. Evaporative humidifiers use an internal fan to disperse air into the unit. This air passes through a saturated wick filter absorbing water. An ultrasonic device bases the moisture dissipation on oscillations at an ultrasonic frequency.

On the other hand, steam humidifiers first boil the water, then cool it down before releasing it into the air. This method brings its advantages and disadvantages, so let’s take a closer look.

5 Benefits of Using a Steam Humidifier

  1. Health Benefits

Winter months bring lower temperatures, causing air humidity to drop down as well. Use a steam humidifier in your home, to reduce symptoms such as dry skin or sinus congestion. Improve your breathing and keep your skin hydrated. Moisturizing air will help you fight nose irritation, dry cough, even cracked lips. Save up on that body lotion in winter months. With proper humidification, the air in your home will be less friendly for germs or bacteria. Keep flu and other illnesses that thrive in dry air away. Steam humidifiers can also contribute to maintaining a pleasant temperature in your space. Not to mention that they can help reduce snoring by keeping the aerial ways from drying out.

  1. Increased Comfort 

As we spend up to 90% of our time indoors (especially in the recent months), the air quality makes a great difference to our bodies. Relative humidity regulation of your indoor spaces means more control over your comfort. The air quality and temperature in the room take a toll on how “at home” you can feel. A steam humidifier will ensure a consistent level of both. This device can help increase the temperature, as it relies on heating the water. Also, as the air is ideally humid, your breathing will feel effortless.

  1. Compelling Hygiene

As they use boiled water as a main source, steam humidifiers produce more purified vapors. With more hygienic steam, your home or work environment will become safer. The spread of illnesses associated with lower air quality can be, therefore, reduced.

  1. No Chemical Boiler Elements 

Generating only pure steam, these humidifiers exclude any dangerous chemical boiler particles. The air will not be, in this case, contaminated with any toxins or decomposed materials.

  1. Protecting the Integrity of Home Decorations  

Humidity influences the conservation of wood items (furniture, floor tiles or musical instruments). Also, the resistance of your wall paint can change depending on the level of moisture in the air. Not to mention, during winter, excessive dry air gets charged with static electricity. And that can expose your sensitive equipments to unnecessary risks. This also reduces the risk of fire caused by static electric discharges, keeping your home safe.

Drawbacks of Steam Humidifiers

Compared to cool-mist humidifiers, the steam humidifiers have an element of heating. That can feel less safe to use in a home with children or pets that can accidentally touch the hot surface. Apart from this, it is essential to keep the device clean. Use distilled water to prevent any residues from getting dispersed in the air. The boiling reduces the bacteria growth, but it is important to keep your device always clean.

Essential Features of Steam Humidifiers

To choose wisely the best steam humidifier for your home, here are a few features to look for.

  • Coverage area

Just like for air conditioners, the surface of the room you wish to place your humidifier in matters. To ensure your steam humidifier works at an optimal level, you should consider the size of the space you use it in. The small portable humidifiers usually come with a recommended room size. The whole home systems have a larger coverage area, as they are by design, meant to humidify an entire house.

  • Water tank capacity 

The capacity of the water tank influences how often you need to do the refill. The bigger the tank, the more water for the humidifier to produce vapors. That also means more time while the device works smoothly. The size of the tank will impact as well how easy or comfortable it is to refill it. If you have back problems, lifting a large tank full of water might not be your favorite activity. As an upside, larger tanks may only require refilling every two days. If you opt for a whole home model of humidifier, you can connect them to the main water supply. Which means less worry for you to remember refilling them.

  • Noise level 

Depending on where you live and the features of your home, your humidifier can be on for more or less time. Based on that, you can prefer to have a silent model, so you don’t feel annoyed by the noise. Large home humidifiers can be noisy while filling the tank or turning on/off. But as they are usually installed in the basement, you will hardly hear this. The steam humidifiers we recommend meet the minimum noise criteria. So you can trust them for a non-buzzing humidifying process.

  • Dimensions 

When adding a humidifier to your home, you want to make the most of the space you have available. A device that is too big can take up too much of your room and even produce too much humidity if not set properly. A humidifier that is too small may not face hydrating the air as you would like it. The available models vary in size, so you can surely find something to match your taste. From a small, fit for a bed table kind of humidifier, to a powerful, full home device to mount in your basement.

  • Mist time & Maximum output

One of the main features listed for a room steam humidifier is the highest amount of mist it can produce in one day. The measurement applies to a time frame associated with the lowest mist setting. Simply because the higher mist levels will take a lot less time to humidify a room. As expected, the surface of the room also plays a role in how much time it takes to reach the desired hydration level. The larger the room, the more time needed to balance the humidity value.

When talking about the maximum output, the device involved is a whole home humidifier. This indicates the amount of water it can add to your whole home’s air throughout a day.

  • Compatibility with essential oils

More common among the portable models, this feature is not so much crucial, but more about comfort. Adding a scented mist to your home can set the vibe, but also provide help with respiratory symptoms. Some models allow you to add essential oils or inhalants in a special compartment. Adding the oils in the water tank is not advisable as it can lead to damage to some internal components.

Other aspects you should keep in mind include: safety features, warranty and how easy to clean the device is. Let’s admit, a remote control for your humidifier can be quite convenient. A timer or an automatic sleep mode allow you to stop worrying about too much humidity piling up. You can sleep or leave the house, knowing the humidifier will turn off by itself. It can stop when it reaches the desired level of humidity or when the tank empties. Some models even turn down the lights at night, so you can rest at ease. You already know how important the warranty is. You should be aware of what it covers and for what period. You don’t want to be just taken by surprise in case something happens with the humidifier. And finally, how easy it is to clean will make a difference on the days when laziness hits. Having to spend too much time to disassemble and clean your humidifier can be a mood killer. And improper cleaning can lead to bacteria growing inside your humidifier. You wouldn’t want that, would you?

How to Take Care of Your Humidifier

Keep the water clean. Most room humidifiers use a gallon of water daily. Changing the water on a daily basis avoids the growth of any mold or bacteria in standing water. Make sure to also wash the tank or filter systems every two to three days. You should avoid using tap water as it contains minerals that can deposit inside the tank.  That also promotes bacterial growth. Released into the air, these minerals look like white dust on your furniture. Use distilled or demineralized water, with a lower mineral content than tap water.

Change the filter. Check the manufacturer’s recommendation. This ensures the air is not contaminated with any germs and your humidifier works well.

Check the humidity level. Verify the level of humidity in your home every few days. Using your humidifier more than needed can worn out the filter or other components. Too much humidity can also lead to health problems and trigger allergies and asthma.
