How to Reduce Humidity during Rainy Days

December 2, 2019


Malaysia has tropical weather year-round, two types of weather which is hot and rainy season. During rainy season, the humidity increases especially in the highland where it experiences cooler temperature than the lowland. Two types of monsoon will occur in Malaysia throughout the year, namely Southwest Monsoon from late May to September and the Northeast Monsoon from November to March. The heaviest rainfall usually during the Northeast monsoon and it would especially affect the east coast of Malaysia and west of Sarawak. Southwest monsoon has a lesser effect on Malaysia since it carries less heavy rainfall. The Northeast monsoon usually would affect a few states on the east coast such as Kelantan, Terengganu and Pahang. During November till January would be the wettest month for Malaysia


By the end of the year, the east coast would be facing the wettest season where the humidity level would rise resulting in the water vapour to be denser than usual. However it does lower the surrounding temperature making it colder. However, over time it will make the condition to be more stuffy and causes much more health problem such as respiratory-related illnesses. When the environment is humid it may cause many unwanted problems such as mould, mildew, condensation, staining, odour, etc.


Some of the effects caused by a high level of humidity at home:


1. Smell or bad odour

High humidity can cause a very distinct odour in your home. This odour comes from breeding of mould and mildew. If you are not sure whether there is a smell in your home try get out of the house and whenever you re-enter your home you can smell something funky rather than fresh air that you just smell.


2. Mildew or mould

If you notice any discolouration or dark spot around your house there is a high chance of presence of mould or mildew in the area. Mildew and mould breeding would thrive in high humidity environment


3. Damaged furniture or home structure

Too much humidity causes damage to wooden furniture or floors and peeling of paint. If you notice any stains on your wall, there is a possibility of moisture from the humidity seep into your wall cause paint to peel. Wood material tends to rot in high humidity environment and even worse cause structural damaged if there is no action is taken. 


4. Condensation

If you notice any surfaces that collect water droplets especially in surfaces such as windows, mirrors, pipes or any other cooler surfaces. Make sure to check the moisture surround these surfaces to prevent spreading.


5. Health problems

High humidity may affect your bodies by allergies, asthma, sneezing, wheezing, headache, shortness of breath, chronic cough, etc. For kids below five years old, they are more susceptible to obtain health problem during rainy season due to change in weather which aggravated those who had already vulnerable and prone to get sick.


First of all, if you have a feeling that your home or the area you live are inclined to be humid, you might want to consider purchasing a hygrometer where it helps measure the moisture level in your home. If your humidity is higher than 60%  you may want to reduce the humidity level.


Below is the list of actions you can take to reduce humidity in your home. 


1. Proper ventilation 

Every area that is susceptible to moisture such as kitchen and bathrooms are properly ventilated. Make sure the exhaust or ventilation fan is turned on when you are working in the area and leave it on until you feel moisture is released. If you do not have an exhaust fan just open your window to allow fresh air to circulate into the room.


2. Fix all leaky and burst pipes

If you notice any wet spots, stain on the wall or moist surfaces, there is a chance water accumulation occur. Accumulation of water may come from a leaky or burst pipe that you might not notice since most of the piping lines are behind the wall. This water accumulation would affect your home structure and humidity level. Fix the broken pipe and it will help reduce condensation.


3. Air conditioning system

If you have an air conditioner at home, it is not just for cooling the air and removing warm air. It can also help in removing moisture and humidity. Air conditioner helps to reduce humidity up to a certain level. It may not be as efficient as a dehumidifier as it works on a thermostat control instead of a humidity sensor control. Make sure you clean your air conditioner filter regularly.


4. Dehumidifier

A dehumidifier is a device which helps to reduce the humidity level by removing moisture trapped in the air. There are two types of dehumidifiers, one using a desiccant rotor (also called chemical type) and another using the principle of condensing (refrigerant type). Depending on the usage (application) and requirement (is it critical), one may use either type of dehumidification system to remove the excess moisture and maintain a constant humidity level.

The measurement of humidity is commonly referred to as percentage of Relative Humidity (%RH) which means the amount of water vapour in the air that it can hold. To achieve and maintain a consistent level of humidity, your HVAC expert considers other factors including (absolute) moisture measured in grams per cubic meter of air.
