Pros and Cons of a Dehumidifier: Do You Need One?

We all know why most of us are inclined to get ourselves a dehumidifier. From helping tackle asthma and allergies to preventing mold growth in our homes, dehumidifiers are in demand nowadays.

Still, many of us also buy them without knowing their drawbacks. Every piece of equipment has its own pros and cons, so it is important for us to do our own research before purchasing it.

And this article will present to you a list of the pros and cons of a dehumidifier, which can give you a brief idea of the product and help you make a well-informed decision on whether or not to buy it.

Pros of Using a Dehumidifier:

  • Excess moisture can attack your respiratory system and also cause dust mites, mold, mildew, and some allergies to grow. Dehumidifiers create a dry atmosphere. Therefore removing humidity from the air can assist in alleviating these issues.
  • By keeping the humidity level between 30% and 50%, dehumidifiers can make breathing easier and more pleasant for asthma patients. This guarantees that you are inhaling neither moist nor dry air, creating a safer breathing environment.
  • Running a dehumidifier regularly will prevent mold spores from growing on your furniture, clothing, bedding, and other items. By removing mold and dust, you are also eliminating invaders such as silverfish, cockroaches, and spiders. 

Useful tip: When utilized in a living room, accompanying a heating system, appropriate ventilation (such as a mechanical ventilation system) and, if necessary, humidity-resistant paint— along with your dehumidifier can help in minimizing mold growth even more!

  • Using a dehumidifier will help your AC function more efficiently since it will help remove all of the humidity from the air, and your AC will not have to work twice as hard. This way, you can conserve electricity and use your fan during summer as your dehumidifier creates a cool ambiance.

Cons of Using a Dehumidifier:

  • A running dehumidifier emits a buzzing sound, which may get louder as it speeds up. This might range from 20 to 50 decibels. Aside from that, the warm air emitted by the dehumidifier might be unpleasant in the summer.
  • Dehumidifiers require maintenance—you must routinely empty, clean, and replenish the water collection tank and the air filter (on certain models).

Useful tip: Installing a drain line that dumps collected water into a floor-level drain will lessen your maintenance requirements and keep you from dashing down the hallway or all over your home towards the bathroom, splashing dirty water.

  • Running a dehumidifier all the time will raise your energy cost.

These pros and cons come with all kinds of dehumidifiers in general. To be more specific, if you’re getting yourself a portable room dehumidifier, it has its own additional pros and cons.

Pros of Portable Room Dehumidifiers:

  • A decent option if you’re renting your place.
  • It is simple to relocate. 
  • The initial cost is lower than that of a whole-house dehumidifier. 
  • No installation is required.
  • It is suitable for one-time usage, such as drying out after a flood.

Cons of Portable Room Dehumidifiers:

  • Less energy-efficient than whole-house models in general.
  • Only removes humidity from one area, leaving the other rooms humid.
  • Requires periodic maintenance to keep mold at bay.
  • Depending on the size of the unit and how much water is removed from the air, collected water must be manually emptied once per day or every other day.
  • Noisier than whole-house models.

On the other hand, if you are going for a whole-house dehumidifier, we have got you covered on its pros and cons, too!

  • The best long-term solution to humidity issues.
