How to choose the best humidifier when sick

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.

FAQs On the Best Humidifier When Sick

1) 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.

2) 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.

3) 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.

4) 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.

5) 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.

6) 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.

7) 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.
