How to Know if You Need a Dehumidifier?


Dehumidifiers are commonly used to reduce indoor air humidity. Keeping humidity levels consistently low is important to safeguard your health and the safety of your home. Excessive humidity in the air can lead to a variety of problems; crazy growth of mould and mites, damage to furniture, and even the health of family members.

You need to be able to tell if you need a dehumidifier by looking for water damage, testing the air humidity, and noting other signs of high humidity.





Condensation on windows and walls usually occurs during the cold winter months, when the temperature outside plummets while the temperature inside rises, and this condensation occurs on window panes and poorly insulated walls, which is most likely caused by too much humidity inside your home.


Mould Spot


Mould spots are usually found in hidden corners of walls, ceilings, floors and bathrooms. If you find mould spots in your home, they should be dealt with immediately, otherwise they can be harmful to walls, furniture and people.




Surveys have shown that many people are allergic to mould and dust mites, and one of the conditions for the growth of these two substances is a high humidity air environment. When mould spores are brought indoors by you from outside and scattered all over the room, together with the high humidity environment they will grow rapidly, which can cause coughing and even allergy symptoms. The same goes for dust mites, which multiply when the air is humid. Using a dehumidifier can reduce the amount of moisture in the air, and some dehumidifiers with HEPA filters can also remove mould spores and dust mites from the air, effectively purifying the air of allergic substances.




Mould can give off a musty or foul smell as it grows, especially if it comes from areas with high humidity such as cellars and basements. As soon as you notice this odour, you should take immediate action. The use of an air purifier with an activated carbon filter can be an effective solution to this odour.


Identifying Water Damage


1.Identify signs of excessive ground water around your home. Walk around your home and look for any signs that the water table is high. If you notice long-term standing water, see a water mark left on the outside of your home, or observe water marks in your basement, you may need a dehumidifier.

2.Search for water stains throughout your home. If you notice water stains on floors, drywall, or anywhere else. If this is so, you might need a dehumidifier to decrease the risk of mold or mildew growth in your home.

3.Notice wood rot. Wood rot inside or outside is an indication of excessive exposure to moisture.

4.Get a dehumidifier if the structure has experienced a flood of any sort.


Poor Ventilation


If you live in an environment where the air humidity is inherently high and you don't ventilate it regularly, too much moisture can build up, as is often the case in unventilated kitchens and bathrooms, for example.


Checking Humidity Levels


Use a professional humidity measuring device to check the humidity level in your home. According to several studies, the comfortable humidity level for most homes is between 40 and 60 per cent. Some dehumidifiers also come with a humidity detection function that makes it easy to check the current humidity level and automatically adjust the dehumidifying power.



In conclusion, if the above situations, must pay attention and solve the problem, otherwise it will lead to your health problems, long-term living in a humid environment will make people easy to sleepy and weak, chest tightness, get rheumatism and so on. Dehumidifier is a very affordable solution.
