Humidifier or Dehumidifier: What Should You Choose And Why?


The humidity level can be defined as the amount of water vapor in the atmospheric air around us.

Due to the changing climate, it varies between very high-value to drastically lower values.

Both these conditions (high and low humidity levels) are not favorable for survival.

To maintain a comfortable humid condition at home, we all need a good humidifier and a dehumidifier.

Humidifier vs. Dehumidifier: Difference

Helpful in enhancing the moisture level of the surrounding airHelpful in reducing the moisture level of the surrounding air
Used during the winters or cold dry conditions (mostly in areas with humidity less than 35%)Used during the extra warm and humid climatic conditions (mostly in areas with humidity more than 50%)

Most recommended for relieving dry skin problems and respiratory issues (for adults as well as infants)Most recommended for relieving allergies by eliminating all the dust mites, molds and mildew from air

What Does a Dehumidifier Do?

Dehumidifiers remove the excess water vapor (or humidity) from the air around you to keep it dry and comfortable to breathe.

It is also helpful in preventing the growth of mold, mildew, dust mites, and other allergens (developed due to more humidity), which ultimately leads to allergies.

These devices are mostly advised to use on hot summer days when the humidity level hits 60 percent or higher at home.

Dehumidifiers are also found helpful in places such as the basement and attics, where damping problems are seen more.

Sometimes the mold present in these areas (due to spring water dampness) is not visible for the time being, but it does have all the traits to affect your health seriously.

With appropriate sealing along with running a dehumidifier device, you can quickly fix these sorts of problems in your home.

What Does an Air Humidifier Do?

Humidifiers perform the opposite function as dehumidifiers.

These devices increase the moisture levels in the air by adding the needed mist or water vapor droplets.

These are generally recommended for places where the humidity level falls below 35 percent.

Dry air conditions can make you suffer from problems such as dry skin, bleeding nose, respiratory issues, etc., which may further give rise to dangerous nasal troubles like asthma and bronchitis.

In winters, when allergies like cold, cough, and congestion are common due to low humidity, choosing a good baby humidifier machine can help get you the best relief.

Do I Need a Humidifier or a Dehumidifier?
