Different Water Damage Scenarios

There are many home conditions that call for quick repairs or total improvements. One of the annoying situations we usually get caught up with is water damage.

It can be caused by natural events such as flooding or can be caused by molds which can be too frustrating.

Water can be damaging if left untreated over a period of time. At some cases, even if you have already dried everything out, dampness is still a major concern.

Here are some home issues we experience:

  • High Humidity level
  • Wall condensations
  • Leaks
  • Poor ventilation
  • Floods

Whether it is your living room, bedroom, and any other spaces inside the house that needs drying, we cannot avoid the growth of molds and bacteria.

And we know that when these culprits are present, our health is at high risk. Usually, molds thrive in almost any material as long as there are high moisture and oxygen present.

Molds need water to flourish and so if you notice, they appear sooner than expected after a recent water or dampness issue.

You can see them thriving in:

  • Woods
  • Insulations
  • Paper
  • And Walls

If molds are present at home, it is best to seal and contain the issue as quickly as you could to avoid further damages and impose further health risks.

However, you can avoid mold build-ups beforehand. When there are many forms of water, dampness, and or condensation, make sure to dry the entire space completely.

  • The best way to get rid of dampness or moisture is to ensure that your house is well-ventilated and free from possible leaks.
  • Open your house or room windows to let the sunlight in and naturally dry the place
  • You can also install extractor fans, especially in the kitchen area.

Using a dehumidifier for drying rooms, walls and other parts of the house has been an efficient method.

They can easily dry out crawl spaces, basements, and other parts of the house where there is high humidity.

If this is your first time using it, then carefully consider these tips.

  • 1
    Measure the relative humidity level inside the room with a hygrometer or through the dehumidifier display itself.
  • 2
    Consider the size of the room versus the size of the dehumidifier so it can work efficiently.
  • 3
    Check to see if your dehumidifier supports continuous drainage.
  • 4
    Run the device on full power or on Laundry Mode for best results.

Where to Place the Dehumidifier when Drying

I know that after reading the first part, probably, your next question would be, where is the best place to put the dehumidifier?

Essentially, you need to check on your hygrometer which part of the house needs dehumidification. From there, work on the following measures:

  • 1
    Inside the most humid room, find the center of it and place the dehumidifier on the floor.
  • 2
    Make sure that it is far from the wall or any furniture. You can set at least a foot away from the closest object in the room. This is to allow better airflow from the dehumidifier.
  • 3
    Leave it working until the humidity level drops within normal


Don'ts in using dehumidifiers

While working with a dehumidifier to dry your room, there are also critical points to avoid:

  • Never place a cloth or piece of clothing on top of the dehumidifier. Remember dampness attracts bacteria and molds.
  • Don’t put the dehumidifier on top of tables or any appliances to avoid any accidents
  • Never leave the tank filled with water, make it a habit to drain it after use

If you are experiencing wall dampness, you can place the dehumidifier near the wall until it dries up. You may also do the same when having window condensations.

Place the device near the window and if your dehumidifier features a Laundry Mode, you may use it for quicker results.

How Long to Use a

Dehumidifier for Drying a


How long to use a dehumidifier when drying a room

You can opt to use a dehumidifier until it feels comfortable. However, the best way to make use of this device is until the relative humidity inside the room gets back to normal.

Again, this is where your hygrometer plays an important role. Room sizes vary per property and the extent to how long you should run a dehumidifier for drying along with other factors.

The dehumidification is influenced by several circumstances, such as the temperature, space or room size, airflow (this is also considering the windows or door constraints) and environmental humidity.

But, all these considerations depend on the RH level. Usually, each dehumidifier offers different settings for every relative humidity (RH) levels.

So, to make it safe, you can run the dehumidifier until the RH level falls to the normal range. A 2L dehumidifier can run up to 6 hours, more or less.

Bear in mind mommies that in order to get the most from your dehumidifier, to do the following:

  • 1
    Make sure to close room door and windows where you intend to run the dehumidifier
  • 2
    The relative humidity level should be ≥ 60%

How To Maintain Your Dehumidifier Filter For Optimal Performance

dehumidifier filter maintenance

After good use of a dehumidifier, it is best to practice maintenance by checking the filter every now and then. The more often you use the device, the more you need to clean the filter.

The filter is a vital component of a dehumidifier since it removes dust and dirt from the air before the air then passes through the coils.

You must clean the filter at least every 2 weeks so that the device will be at its peak performance. Regular filter cleaning also ensures that the airway is clear.

If your dehumidifier has an anti-bacterial filter, do not wash it with water as the coating might be dissolved. Simply use a vacuum cleaner or hoover it to remove dust and dirt.

Other important dehumidifier parts that should be maintained are the water tank and coils. Make sure there are no damages to these parts as they too play important functions.
