Here are the signs that you need to be able to tell that you really do need the power of a dehumidifier.

1. Undesirable formation of mold and mildew spots on the ceiling, walls, corners,
window panes, etc. that gives of an indescribable but definitely unpleasant odor. Look around your house, if you see little black or dark spots and grayish spots, you have a mold and mildew problem. Simply wiping them off or using high-performance window cleaners won’t fix it. Mold and mildew accumulates even after removed and spreads when left unchecked.

2. When windows start to bead up water – this means condensation. Condensation
is accompanied by other visible signs like vapor and fog formation. Highly condensed windows can be a breeding ground for mold and mildew. Again, if left unchecked, mold and mildew can spread across your home and the problem will be harder to fix.

3. Furnitures or anything made of wood in your home starts to rot. You know what is more annoying than rotten wood? Termites. Unwanted pests like termites are attracted to rotten wood. If you see that wood furniture are starting to rot, you should already consider getting a dehumidifier. Excess moisture at home can not only damage wood, but can also attack and destroy dry walls, sealants, and even the foundation of the house.

4. Water stains are spotted in areas like the basement or near the basement.
When you are starting to spot gray water level marks on the basement floor, or yellowish stains on the ceiling of your home, this means excessive moisture start to seep through the areas already and may do bigger damage than just staining parts of your home. Start investigating, it could be pipe damage or lack of ventilation which can be effectively resolved by installing a dehumidifier at home.

In the case that you are still unsure of getting a dehumidifier as another necessary machine to operate at home for the safety of all family members and the structure of your housing, here are some benefits you get for having a dehumidifier.

Benefits that a dehumidifier brings

1. Dehumidifiers makes your home less hospitable to proliferating dust mites,
mold and mildew. With the humidity level lessened, air is no longer a thriving environment for those unwanted bacteria,allergens and particles. It basically eliminates the possibility of mold and mildew build up on your home furniture, walls, and even closets and clothing. Dampness of the air also gets into electronics. So it may do some damage to your television and other appliances as well.

2. No more unpleasant odor. Mold and mildew have certain unpleasant smell. With the dehumidifier operating, these problems will be eliminated, leaving no trace of its odor.

3. It minimizes condensation. Cooking, heating water, hot bath, doing the laundry and any household chore that deals with water or with heat combined – can cause condensation. Condensation can be minimized with the use of a dehumidifier. As an end result, wallpapers are not peeled off, no damp patches or water stains on walls, no and more rotten wood.

4. Dehumidifiers are basically installed then left to operate on its own. A lot of units, have built-in humidistat control option so that you can set your preferred the humidity level. Check up on the unit once or twice a month just to make sure it is dust and leakage-free. It requires minimal hands-on handling and results are apparent when you can smell the musky odor less or not at all and when you feel the air is lighter and drier.

5. It helps your air conditioner run more efficiently and live longer. In a very humid environment, the AC does the function of cooling the air and removing moisture. The
dehumidifier can do the function of removing moisture from the air so that the AC can focus on just cooling the air. Balancing the use of the two can yield lower energy costs and prolong the equipment life of each.

6. Dehumidifiers actually reduces allergies, skin irritation and is good for the respiratory system. No more damp feeling. The air is easier to breathe in and less heavy compared to breathing in damp and moist air.

Factors to consider in buying a dehumidifier for your basement

1. Dehumidifier size

Before you decide on the size of the dehumidifier, make sure you have an idea of the square footage of the room or location you want to dehumidify. Besides this, you also have to know the level of moisture present. While it is best to get professional help to perform this, you can also opt to purchase devices that can measure the level of humidity. (Important note: the drying capacity of a dehumidifier is measured by how much pints of water it can remove from the air within 24 hours.)

2. Water capacity

Most portable dehumidifiers have self-draining or self-purging system and come with a long drain-hose, it can empty water directly to where it should go. When buying a dehumidifier it is important to look at the bucket size and water capacity. (Tip: the more pint of water a dehumidifier can extract, the more it is expensive.) Selecting the right but rather costly dehumidifier eventually pays for itself because of the problems it solves and the benefits it brings.

3. Mobility

If you are the type of person who wants to move things around the house, be it with purpose or not, then you should consider a dehumidifier that is compact, weighs less and/or has wheels and easily mobile. By looking at this factor, you should also put into consideration the length of power cord and the drain hose. So that you can put your
dehumidifier anywhere without the need for extension cords and extra drain hoses.

4. Automatic or Manual shutoff

With the technology that we have today, even dehumidifiers know when to work and when to just stop working. Most dehumidifiers’ humidity level can be set to the preferred level because of built-in humidistat control. When reached, dehumidifiers automatically shuts off and restarts again if the humidity level increases more than the preferred or set level. When it comes to automatic shutoff, some dehumidifiers have an overflow protection valve that causes the dehumidifier to shut off when the tub or drain pan is full and needed to be emptied.

5. Defrosting feature

One of the most important features that you must look for in buying a dehumidifier
especially if you live in an environment where the climate is cold most of the time is the defrost feature. You must look for dehumidifiers that can still function at such a low temperature as 30 degrees F. It will cost you more for this feature, but these types are not affected by extreme cold conditions not to mention, it will cost you less expenses in terms of having to replace the unit from damaged caused by extreme cold.

6. Humidity control

Opt for a dehumidifier that has built-in humidistat so that you can control the humidity level to which the dehumidifier will maintain. Optimal relative humidity during the summer should be 40 to 50 percent and in winter it should be 30 to 50 percent.

7. Quite in operation

You may also want to go for a quiet operating dehumidifier. Some operate so noisily that can be a nuisance and bothersome for family members or guests.


Dehumidifiers are just as important as air conditioning units. For others, even more so. Now
that you have the knowledge on why humidity levels needed to be checked around your
home, time to start working. Don’t let the mold and mildew spread and feel welcomed into
your home.
