Why Is My Aircon Filter Always Dirty?

Why Is My Aircon Filter Always Dirty? Air conditioning is more of a necessity than a luxury in a country like Singapore. People rely on air conditioning to maintain the temperature and humidity for the better part of the year.

The problem is that air conditioning consists of many different parts. None is more vital than the Aircon filter. In case the Aircon filter is dirty, the efficiency of the Aircon reduces significantly.

Unfortunately for many people, the Aircon filter becomes dirty quite frequently. If you have experienced the same, you might also think, why is my Aircon filter always dirty?

We will answer that below and help you understand how the Aircon filter works. Once you know the reasons and how the filter works, it is easy to understand the causes and work towards executing solutions.

How Does Aircon Filter Work?

Before the aircon releases the air into the room, it passes through the filter. The filter’s job is to remove any contaminants and impurities from the air. This is done to ensure that the air being released into the room by the Aircon is entirely healthy.

Now that you know the basic job of the filter and the Aircon mechanism, it is time to understand why it gets dirty so frequently.

Why Is Aircon Filter Always Dirty?

Why Is My Aircon Filter Always Dirty?

There are a few reasons why your Aircon filter is always dirty. We will cover them below so that you can take remedial steps accordingly.

1. Substandard quality:

Every filter has a filtration capacity. If you’re going with a substandard filter, it will get dirty quickly. In a humid country like Singapore, the number of contaminants is also on the higher side. That is why substandard filters will get dirty quite quickly.

2. Large temperature difference:

The more significant the temperature difference between the set Aircon temperature and the temperature outside, the harder will the air conditioning work. It means that more air will pass through the filter as well. If more air passes through the filter, more contaminants will also pass, and therefore the filter will get dirty rapidly.

3. Presence of mold in the vicinity:

Usually, we associate the mold with the walls. However, a few particles of mold can also get into the air. Since the air conditioning is rotating that air, the mold can clog up the air filters quite quickly. If you notice that your Aircon filter is getting clogged quickly, it is time to look for mold on your premises. Once you eliminate the same, the air filter will not get dirty at the same pace.

4. Too many contaminants:

Many people in Singapore live in the vicinity of busy roads. The point we are trying to make is that the air quality in the vicinity of busy streets is not that good. It means that the Aircon filter has to deal with more particulate pollutants. In that case, it will get dirty quite quickly.

5. Excessive soot:

Excessive soot is one of the main reasons why an Aircon filter can get dirty. If you do not frequently clean your premises and it consists of excessive soot, there is nothing you can do about the Aircon filter. You need to start cleaning your premises more often to prevent clogging of the Aircon filter.

6. Frequent use of fan mode:

Almost every Aircon has a fan mode as well. In the fan mode, the volume of air that rotates through the Aircon is much higher. When more air goes through the filter, the number of contaminants that the filter catches will also be more, and therefore the Aircon filter will get dirty faster.

Usually, a fan mode is not needed that frequently. If you have turned it on accidentally, it is a good idea to switch to another mode so that the filter does not get dirty that often.

7. Leaky air ducts:

The problem with the leaky air ducts is that they can suck in the air from the attic or other parts of your home which are not that hygienic. Unhygienic air can clog up the air filter at a faster pace. Because of the same, this is another reason why your air conditioning filters can get dirty at a faster pace.

8. Presence of pets that shed:

Anything that contaminates your home’s air will result in faster clogging of the air conditioning filter. Similarly, if you have pets at home that shed, the hair can easily get into the air conditioning system. However, the filter will prevent them from being released back into the room. In turn, the filter will get clogged quickly.

These are the main reasons an Aircon filter can quickly get dirty. Now that you know the reasons, it is time to understand how to remove the Aircon filter from the air conditioning system and wash the same.

Dangers of Dirty Aircon Filter:

The risks of a dirty Aircon filter include:
