If you are struggling with dampness in your home and see water running down your bedroom windows or walls then it might be time for you to invest a dehumidifier to tackle the issue…
In this article will look at various questions that get asked about dehumidifiers such as will they get rid of damp? Why is there water running down my bedroom windows? Can you sleep with a dehumdifier running? How much water does a dehumidifier remove?
When to use and where to place your unit? Can you run them in winter? Will they make you sick? Do they make your room warmer? And how many dehumidifiers do you need for your house?
Will A Dehumidifier Get Rid Of Damp?
A dehumidifier removes moisture from the air in your room and can indeed get rid of damp and assist in drying out damp areas however if your dampness is coming from a leaking pipe or some other issue other than the moisture in your air you will need to fix that issue otherwise it will continue to reoccur.
To give you an example of how powerful a dehumidifier is in assisting with damp removal they have proven to be very effective (time and time again in thousands of homes) in helping to dry out basements that have been flooded.
Here is a quote from a user of the Midea Dehumidifier
We have the dehumidifier in our basement. We have an older house and live near the water, so we deal with a lot of dampness. This takes care of the problem.
There are many such statements from people using dehumidifiers to remove dampness and I personally have a dehumidifier and it has been very effective at removing dampness and keeping it under control in our bedroom.
Why Are My Bedroom Windows Wet In The Morning?
The air inside your house has moisture in it and depending on a number of factors such as heating, drying clothes, steam from showers, cooking, and so on it can be quite a lot of moisture.
The air inside your house is also warmer and warm air holds moisture so much better than what cold air does so when your warm inside air meets the cold outside air on your outside walls and windows your inside air cools down and loses the moisture.
It usually appears on your windows first as glass will be the coldest surface however it can also be on your walls as well but less noticeable.
So how do you stop it?
Many people try cracking the window open a little bit and it seems to work for some however in most cases it is not enough. Venting in your house is an important factor so make sure you haven’t sealed over any of the vents on your outer walls they are there for a reason.
You should also look at getting a dehumidifier… these machines will remove the moisture from the air. In our bedroom, we had over 80% humidity and set the dehumidifier on auto mode at 50% and we were amazed at how much water these machines removed from the air.
The dehumidifier helped immensely with the issues we had with water running down our windows and walls.
Should You Sleep In A Room With A Dehumidifier?
There are no issues as far as safety is concerned with sleeping in a room with a dehumidifier. As with anything, there is a lot of misconception and unwarranted fear about what affects a dehumidifier might have if you sleep in the same room all night with one going.
People even think you could become dehydrated… it does not pull moisture out of your body and your air will still have some moisture in it so that just seems to be far fetched.
I personally have slept in my bedroom with the dehumidifier going all night with no problems and rather enjoy the background noise (just like having a fan going), however, my wife can’t sleep with the noise so the biggest issue is can you sleep with the sound of it or not.
Another consideration is where you set it up – our bedroom is small and we are limited for power outlets so we can only position the dehumidifier in one spot rather close to the bed (near the outside wall) and it can blow out some cold air – so that could be another issue if you can’t position it away from your bed.
How Much Water Should A Dehumidifier Collect In A Day?
This really depends on a wide variety of factors. Where you have it… How big is the room… How powerful is your dehumidifier… How damp your house is… and how much humidity you have.
However, for myself when we first got our dehumidifier we put it in our bedroom that was very damp and ran it continuously on the auto mode. Our humidity was about 88% and I set it for 60% at first and we had to empty it about twice every 24 hours – so about 2 gallons of water a day.
We left it running like this for about 3 days and every day it extracted less water until it got down to about 1 gallon a day, I than set it 50% and it keeps the humidity at 50% and I only have to empty it once a day at the most.
We also now only run it during the day and it seems to keep the dampness in our bedroom under control.
If you had your dehumidifier in a basement with a lot of damp issues then you could extract 4 gallons a day or more depending on the situation.
Most people connect the dehumidifier to a drainage hose in these situations so they don’t have to constantly empty the unit by hand.
Where Should I Place My Dehumidifier?
You want to place the dehumidifier in the room that has the biggest issue with dampness. Where you place it will be dictated to by where your power outlet is and the length of the cord. If you don’t use an extension cord you will only have about 6 feet or so to play with.
You don’t want to have it directly in front of your power outlet for safety reasons and you must give the machine enough clearance to draw in and blow out air.
My machine in the bedroom is situated about 2 feet away from our outside wall where it works more efficiently.
Some people find by placing the unit strategically between 2 rooms – such as an open dining room and living room – that you can get the moisture out of more areas.
Also, if you have a basement it is quite often the best place to start because if you get the basement dry it will stop damp rising into the rest of the house.
However, a dehumidifier can be used in any room including the living room, dining room, kitchen, bathroom, laundry, basement, and crawl spaces.
When Should You Use A Dehumidifier?
If you are seeing moisture running down your walls and windows or if you see mold and your rooms have a musty odor then it is time to get a dehumidifier onto the job.
It doesn’t matter if you use the dehumidifier at night, during the day, continuously, in winter or summer.
If you know your house has high humidity, if you live in an area that gets very humid, if you live next to a river, dam, or other waterways, if you have had a pipe leak or cleaning up after a flood a dehumidifier can help fix a problem or prevent it happening in the first place.
Can Dehumidifier Make You Sick?
A dehumidifier is simply a tool that will help you combat dampness in your home and in most cases is totally safe.
It is possible for viruses to thrive in areas of low humidity however most dehumidifier manufacturers recommend keeping your humidity level at 50% so if you follow the instructions you should have no health concerns at all.
If you suffer from dry skin or itchy eyes due to the lack of humidity just bump it up to 60% but really it shouldn’t cause issues at 50% however we are all different with various sensitivity levels.
Another thing to be careful of is not leaving water in the unit to sit there for weeks on end gathering mold, etc. So just makes sure you empty it completely when not using it.
But overall, a little commonsense is all that is needed to run a dehumidifier safely.
Should I Run My Dehumidifier In The Winter?
Well… I certainly do because that is when I have the issue of water running down my windows and walls.
But… my bedroom is warm (not comfortably warm but not freezing) – we have heating elsewhere in the house so the bedroom would never get colder than 50 degrees.
So a lot will depend on how cold the room gets that you have your dehumidifier in. If below 40 degrees Fahrenheit it is best not to use a dehumidifier as it can freeze up.
In most cases, it is also not advisable to run a dehumidifier in winter if the humidity in your home is below 40% (why would you want to anyway?).
If you have rooms such as a basement that gets below 40 degrees it might be best not to use a dehumidifier in winter.
However if you have high humidity and dampness issues it might worth trying to push the boundaries a little bit (perhaps as low as 30 degrees) and monitor how your dehumidifier performs.
An alternative would be to add heating into the room in winter if your dampness issues have to be dealt with and then you can safely run your dehumidifier – you only have to heat the room up enough (above 40 degrees) so that your unit will not freeze.
You can also buy dehumidifier/fan/air conditioner/heater combos that would help with this situation such as the Whynter (available from Amazon)
Does A Dehumidifier Make A Room Warmer?
I run mine in winter and it definitely doesn’t make my room any warmer. A dehumidifier is not designed to either warm or cool the air just remove moisture.
Now it is possible it could affect your air temperature just because of the process involved however it is usually not enough to be concerned about and certainly a dehumidifier is not the machine you need if you want extra warmth.
As far as cooling… while the dehumidifier does not cool the air the lower humidity will result in you feeling cooler anyway.
How Many Dehumidifiers Do You Need In A House?
Most dehumidifiers are lightweight, portable, and easy to carry so if you haven’t used a dehumidifier before I would recommend just getting one and moving it from room to room as needed.
Once you have your worst room under control you can rotate the machine through some of your other rooms and see what a difference it makes.
If you have a large house with significant issues with dampness then perhaps consider more units but make that decision after you see how well your first dehumidifier performs.
In summary, a dehumidifier is an excellent device for getting rid of damp in your home. They are easy to use, can be placed anywhere, and provides a way for you to combat musty smells and mold.
