Why is it important to change the filter?

Ah, the filter. That unsung little hero, living deep within our appliances and systems, works tirelessly to keep the air clean, the water pure, and the motors running. But why is it so important to change it regularly? 

First, because a saturated air filter is like a wet towel trying to absorb more water: it simply can’t take any more. Dirty filters allow allergens, dust, and other pollutants to circulate freely throughout your home, which can worsen respiratory problems and allergies. So if you want to breathe clean air, make sure you change that filter.

What’s more, a blocked or less-than-perfect filter means your systems have to work harder to achieve the same result. Not only does this increase your energy bills, but it also contributes to wear and tear on the appliance. As you know, it's better to maintain your air conditioner by changing the filter regularly than to face the cost of replacing the unit due to neglect. Regularly changing the filters helps extend the lifespan of your equipment, preventing early breakdowns and costly repairs. 

When is the best time to change the filter?

The main air filters are designed and built to last for the equipment's entire lifespan. Yes, you read that correctly. However, there’s one important exception: if you spot any damage, then it's time to replace them. The key to these filters lasting as long as possible lies in handling and cleaning them correctly.

How often you should clean the filter depends on several factors, but as a general rule, it should be done every two weeks. 

Now let’s talk about secondary air filters, such as deodorising or titanium apatite filters, which are fitted in some Daikin models. As a general rule, these filters should be replaced every two to three years. This depends on the environment and how much you use your system. If the air in your area is especially dusty or you use the unit frequently, you may need to change the filters more often. 

How to change the filter: step by step

Changing the air conditioner filter is easier than you think. Simply follow this easy step-by-step guide to ensure your system works at its best and keeps the air in your home clean and fresh.

Step 1: Switch off the system

Before you begin, ensure the air conditioning system is turned off. Safety first: turning the system off eliminates any risk of electric shock or damage to the equipment.

Step 2: Locate the air filter

Filters are usually located near the main air conditioner unit or in the air return duct. If you’re not sure where to look, check your system’s user manual. Some systems have more than one filter, so be sure to check all possible locations.

Step 3: Remove the used filter

Carefully remove the used filter. If it's very dusty or dirty, place it directly into a bin bag to prevent contaminants from dispersing into the air. This is also a good time to clean around the filter slot and remove any dust or dirt.

Step 4: Check the new filter

Before fitting the new filter, check it’s the right size and type for your system. Most filters have arrows to show the airflow direction; make sure they are aligned correctly, as shown in the system's instructions. Also check that the filter is in perfect condition, with no damage or defects.

Step 5: Install the new filter

Fit the new filter according to the manufacturer’s instructions, ensuring the airflow arrows point the right way. Close the cover or grille over the filter, making sure it’s secured properly to stop any unfiltered air leaking through.

Step 6: Turn on the air conditioner

Once the new filter is fitted and everything is in place, switch the air conditioning system back on. Let it run for a few minutes to ensure the airflow is steady and there are no unusual noises or other issues.

Congratulations! You’ve successfully changed your air conditioner filter. Now you can enjoy fresh clean air, knowing you’ve improved your system’s efficiency and helped create a healthier environment at home.

A few extra tips

• Make a note of the date: record the date of change on the filter or calendar to remember when to perform the next one.

• Buy extra filters: having spare filters to hand makes life easier. Purchase a few at once so you don’t run out just when you need them.

• Regular maintenance: as well as changing the filter, consider booking an annual air conditioning check-up. This makes sure the whole system is in optimum condition.
