Maintaining a proper humidity level indoors can be helpful for our health. If there is only a little humidity in our home, some discomfort problems will happen, like chapped lips, cracks in our wooden furniture, etc. However, this doesn’t mean too much humidity is better. On the contrary, too much moisture can cause other issues, like promoting the growth of mold and mildew, leading serious health issues. For these reasons, if the humidity level is very high indoors, you really need a dehumidifier to help you remove excess moisture from the interior air.
Before deciding to buy a dehumidifier, you should know the humidity level. This is very easy, the only tool you need is a hygrometer which can help you accurately measure the humidity level. Once you know the level, you can know whether you need a humidifier or a dehumidifier. Such a hygrometer is a very useful instrument for measuring the home moisture. Generally, Optimum Humidity Zone is between 40% and 60%. If the relative humidity level is over 60%, you need a dehumidifier. If the level is lower than 40%, you need a humidifier to add humidity.
Some people only need a dehumidifier at certain times of the year. For example, when there is plenty of ground water runoff in spring, the humidity level increases and a dehumidifier is essential, while during other seasons of the year, it doesn’t need one. On the other hand, other people may need one to maintain a proper moisture level all year around. Sometimes, we only need a dehumidifier to reduce the humidity level in one room, or in a corner, or in one area in the home, so a small and compact model is also useful.
Once the high level of moisture is detected, the first thing is to turn off any humidifier or remove anything that can cause the humidity. And then, we need to do something to remedy the situation. In this article, we will discuss the most common signals when the humidity level is high and such a dehumidifier is essential to use.
1. Condensation is found on the patio door or windows.
If you discover water beading on your window, a vapor or fog on the glass, or condensation on the interior glass, it probably means the humidity level is very high due to a large amount of moisture in your room.
If you use a large humidifier, this may happen and it will output too much moisture in the room. This is not a good thing. Moisture will build up on a window and finally becomes liquid water that will rot wooden casings. What’s worse, wetness will promote the growth of mold. You will find some dark or black grunges in the track of the door or on the bottom of window trims. These grunges are caused by mold.
Firstly, you need to turn off any humidifier immediately and then you need to downgrade it to output less moisture in the future. If the high moisture is caused by the large output, you just stop it and open your window to allow fresh air to enter your room and the moisture level will be remedied as soon as possible. However, if other things cause a high moisture level, things seem to be a little complicated and not easy to correct. For example, humidity present in the construction materials can also increase the moisture level. In these situations, proper room ventilation is very important.
Some indoor moisture problems are caused by outdoor climates. For example, if it rains for many days, your room will have a high humidity level. And a dehumidifier is effective to reduce the humidity level.
2. Mold Spots are found in corners of the walls or on the Ceiling
As vapor rises, mold spots are often found in the corners of the walls or on the ceiling in the bathroom because of these bathroom moisture problems. This is because bathrooms don’t have enough fans to draw out steam and draw in fresh air from the outdoors. Therefore, bathrooms often have problems of mold.
Mold can easily grow almost anywhere, like on the ceiling, on the wall, around/under the toilet, or behind the bath. Some moisture problems are caused by a leaky plumbing or toilet. Excess moisture can promote the growth of mold, which can cause serious health problems. You may not see the mold, but it is just there and affects your health.
To solve this problem, running a dehumidifier can help to remove excess moisture from the air in these areas. However, just remember a long-term solution should be found, based on the root of the problem. A dehumidifier is helpful to reduce the humidity but the cause must be found and cannot be neglected.
For people who have found the cause and plan to repair such as repair walls and remove mold, you should choose a paint which is mildew resistant and can seal areas that have been repaired. Or, mold will make a comeback.
Other areas, like garages, closets, storage areas or basements rooms, can have moisture problems because these areas are easy to trap moisture. Mold spots, as well as dripping spots are often found below windows. Rotting casings and faulty window seals can cause these similar problems. To solve these problems, you may need to replace your windows as well as its frames, and change the sheetrock and insulation, making sure all the wet areas can be removed.
3. Musty Odor or Smell
If there is a musty odor in garages, entrances, crawl spaces or basements, it is probably caused by the mold and mildew. This problem may be caused by construction sealing problems, improper door/window seals, and wet basements. If you find musty odor, you can check these problems.
Anytime a musty smell is detected. This means mold is somewhere and it is not healthy for everyone. A dehumidifier is helpful but you also need to find the root problem and find a final solution to prevent from recurring in the future. These mold areas need to be dried.
4. Recurring Spring Water Run-Off Dampness
In some areas, spring ground water dampness is really a recurring problem. And if you have purchased a new home and find grayish or white water level marks in the basement, a dehumidifier is needed to remove the moisture from the air. Plus, you need to investigate the specific reason that why the basement tends to water.
5. Buying a Home? Inpect for Mold, Water Stain Marks
If you plan to buy a RV or home, you should check the possible excess moisture problems which could be a health concern. Once you have found these problems, you should ask why and whether any remedial action was undertaken. If you don’t know how to solve this problem, you can bring in an expert to help you.
