Criteria Used for Evaluation. Humidifier Pros and Cons

Overall, there are the most important things to consider when purchasing best humidifiers when sick. Pay attention to the following unique features:
  • product's quality;
  • price;
  • etc.
Below are the things to put into consideration when choosing the best humidifier for sickness.

Aromatherapy

Aromatherapy involves adding essential oil to a humidifier I order to take advantage of its therapeutic value. Essential oils are known to help boost energy, aid digestion, and relieve stress, among other numerous benefits depending on the oil content. Take advantage of this feature by purchasing a humidifier with an essential oil chamber.

Capacity

As always, the capacity of a humidifier should be taken into consideration before purchase. The unit should be able to humidify the room enough to cause relief. Always measure your room size and go for a unit that can do the job.

Top-fill design

Top-fill design in humidifiers, enhances two qualities. Firstly, it makes refilling much easier. Instead of the traditional style of detaching the tank and refilling it, you can simply pour in water while the tank is still attached. The opening at the top of a humidifier also allows you to easily clean it since most can conveniently accommodate the hand of a full-grown adult.

Noise level

The aim of purchasing a humidifier is to relieve an existing illness or discomfort of the body. Therefore go for a product that is both quiet and relieves you. This combination does exist and is easily found in ultrasonic humidifiers.

Auto shutoff

The auto-shutoff feature protects the humidifier, and you from potential overheat hazards. A unit that keeps running after the water dries up, tends to overheat and damage after a while. This is not safe, and in rear cases, can cause a fire.

Do humidifier help when sick?

Yes. Humidifiers are especially useful when dealing with cold and flu-related sicknesses. Cold is characterized by dry sinuses, bloody noses, and cracked lips, and humidifiers relieve them by adding moisture to the air.

Cool mist humidifiers can help ease symptoms of colds and some respiratory conditions. During use, ensure you clean the unit properly, and prevent molds and other contaminations from getting in. Not doing this could make the sickness worse rather than alleviating it.

How does a humidifier help when sick – Do humidifiers clean the air?

The main function of a humidifier is to increase the amount of moisture in the air. Many infections causing agents like viruses thrive in the low humidity and eventually find their way into the body. Humidifiers get rid of them by attacking their habitat, therefore redoing their numbers and, as a result, the chance of being breathed in by you.

If you are already infected, it follows the same principle to help you feel better. Moisturizing the airways creates an uninhabitable atmosphere for disease-causing organisms, reducing their effectiveness and helping you breathe better. Over time, your body would overcome these infections, and much credit can be given to the humidifier.

A humidifier does not directly clean the air but creates an atmosphere that is unconducive for infectious organisms. We can safely say that it indirectly cleans the air.

When sick, what’s better, a vaporizer or Humidifier?

The main difference between a vaporizer and humidifier is that humidifiers breaks water into tiny droplets and release as mists, while the vaporizer heats water till evaporation in order to add humidity to the air.

Although different, they both achieve the same goal, which is to increase the overall level of humidity, and have their respective advantages.

A vaporizer’s steam is very clean and does not contain harmful organisms because it is heated to 100 degrees before being released. With a humidifier, on the other hand, contaminations can creep in as a result of poor cleaning habits.

Vaporizers, however, poses a risk of burns due to the high amount of heat involved. They could also be more difficult to clean because of mineral deposits left behind after heating. Generally, humidifiers are safer to use around babies than vaporizers because they involve less heat.

They should, however, be cleaned properly to prevent it from becoming a breeding ground for bacteria. Both products need frequent and proper cleaning.

When it comes to picking one between these two devices, it’s really down to personal preference since they cost around the same price and achieve the same goals.

Cool or warm mist humidifier for sickness

Warm mist and cool mist humidifiers are both effective in equal measures when humidifying the air. When steam makes its way into your lower airways, it becomes the same temperature regardless of whether it started out as cool or warm. What matters most is that the humidifier is free from contaminations like molds or bacteria.

Cool mist products are just as effective as their warm mist counterparts, and the best way to manage impurities getting into the units is to use distilled water only.

Can humidifiers make a cough worse?

When not used appropriately, a humidifier can actually make a cough worse than it was before the humidifier. Contaminants like mold and dust mite thrive in highly humid environments, and when a humidifier is allowed to increase humidity beyond the safe range, it invites more infections.

Asides over humidification, making use of a dirty humidifier could also worsen a cough. A dirty unit containing molds and bacteria would spread the organisms along with its mist, therefore creating a contaminated are for you to breathe in. This worsens coughs.

Can humidifier cause pneumonia and worsen cold

A humidifier can worsen pneumonia symptoms, which are originally caused by viruses, bacteria, or other irritants. When not cleaned properly, the humidifier accumulates bacteria and irritants like mold spores and releases them along with its mist. These organisms could cause pneumonia symptoms to manifest as a result, and worsen already existing cold.

Is it bad to inhale the vapor from a humidifier

Inhaling vapor directly from a humidifier poses the risk of burns (if it a warm mist unit or vaporizer) or causes sickness if the humidifier is dirty.

Asides those two risks, inhaling vapor from a humidifier is safe and would not bring any harm to you. Taking in the mist directly is known to have a faster impact and quicker relief on the nasal airways, but only when you do it right.


Although a humidifier can help ease symptoms of a sickness, it can also worsen it when not used properly—the best humidifier to use when sick is the Elechomes Warm and Cool Mist product. With a 6L tank, It offers 50 straight hours of runtime and can humidify 500sqft. The important aromatherapy is also present, allowing you to use essential oil.

In its recommended space of 1,900sqft, maintains the humidity level between 40 to 60%, helping you breathe easier and more comfortable. It is suited for use in large-sized rooms.

Evaporative humidifier

Evaporative humidifiers create moisture by heating water to steam and releasing it into the atmosphere. When saturated, the air cannot hold any more water molecules, and humidification stops. With an evaporative humidifier, you cannot over humidify your room.

TaoTronics Cool Mist Humidifier, 4L Ultrasonic Humidifiers

Capacity

The capacity of this humidifier does not top the chart among its counterpart in any way. It is a moderate humidifier built for small to fairly medium-sized rooms. It has a 4L water tank capacity and gives a runtime between 12 to 30 hours on a full tank. There are three mist levels to choose from, and the device can be set to run on any level you choose.

Clean mist generation

Perhaps the best quality of this device, the humidifier, produces very clean mist due to a well-filtered humidification process. At the bottom of the tank is a dustproof sponge that sits at the opening through which water flows into the humidifier.

This sponge absorbs dust particles in the water, therefore cleaning the mist. Also, this tank is a microporous cartilage filter that also cleans the water. With these two layers of filtration, the water is cleaned thoroughly, and clean mist is released as a result.

These filters, however, do not do well in capturing mineral deposits in the water. As a result of this, it is prone to releasing white dust along with the mist.

Easy mobility and auto-shutoff

The dimensions of this humidifier are 8.07 x 5.31 x 11.81 inches, which makes it a little bulky in size. It, however, weighs only 3.5pounds to be very light. A handle is built into the top side of this humidifier, allowing you to grab and carry around with relative ease.

It also has the auto-shutoff feature that monitors the level of water in its tank. The humidifier dries up on water running out.

Nightlight and top fill

For those who like their sleep with a bit of glow at night, this unit has a very nice blue night light. This makes it suitable for a baby room. The unit is also designed with a top fill that makes it easy to refill and wash the water tank.

Pros:

  • Fairly large 4L water tank capacity allows it run for 12 – 30 hours depending on the speed
  • Dustproof sponge for preventing dust from passing through the base of the unit, and a microporous cartridge filter for cleaning the water
  • Auto shutoff when water runs out

  • Nice night light glow for a more soothing feeling

Steamfast might not be one of the most popular brands of humidifiers today, but it is surely one of the good ones. This model of humidifier is good at what it is designed to do and comes at a good price tag.

Capacity

With the lowest tank capacity of all products on our list, this unit has only 1gallon capacity and can run for 24 hours on a full tank. What is impressive, however, is how much moisture it can produce per day. At 2 gallons, it generates more moisture than many other more expensive products.

It is designed to humidify small-sized rooms, however, which is a big letdown compared to its mist output rate. Although these are average specifications, it is very good for the unit’s price.

Filter free design and auto-shutoff

Its filter-free design means you would require a far lesser running cost to keep it going as opposed to devices that you have to change filters frequently.
