What is a Filter?

The filter of your AC system is vital for removing dust, pollen and anything harmful from the air. Air filters are beneficial for everyone as they improve air quality and have added health benefits too!

From time to time, your air filter gathers dust and becomes clogged, this can block the airflow and reduce your systems efficiency, causing a rise in your energy bills. Some types of filters are reusable and just need cleaning whilst others need replacing.


The different types of air conditioning filters


Pleated filters are a cost-effective option. They are extremely efficient, known to trap smaller airborne particles than the fibreglass filters as their pleats give them a wider surface area. When it comes to maintaining the pleated filter, it needs replacing now and then if it becomes clogged. 


Reusable filters can be cleaned and used again. These are cost-effective filters designed for someone who doesn’t use their air conditioner that often or someone who keeps it on a low setting. This filter is not very efficient when it comes to removing smaller airborne particles.


Fibreglass filters are one of the cheapest, most popular options out there but they aren’t the most efficient. These can’t be reused; therefore, they need replacing. 


Electrostatic filters are one of the most efficient, costing you a little more than the average filter. These filters have self-charging fibres which use static electricity to trap airborne particles. When it comes to maintenance, these will need replacing. 

Would a Reusable Filter be better than a Disposable one?

Reusable filters are great as they save money in the long run and can be used over and over again; all it takes is a quick rinse. Disposable filters tend to trap more particles and are more efficient but need replacing every 1-2 months.


When should I change or clean my airfilter? 

Your air filter should be changed or cleaned every couple of months as hazardous particles can accumulate and block the filter, reducing its efficiency. These contaminants can make their way back into the air, making it even dirtier than before and cause a range of health problems.

A dirty air filter can cause an air conditioner not to work properly. The most common cause of a faulty air conditioning system is a clogged filter. 


How do I change my filter? 

First, make sure the system is turned off. In a duct system, the filter is placed in the outdoor unit and can be removed by unclipping it. In a ductless system, the filter is found in the indoor unit and can easily be unclipped. 

How do I clean my reusable filter? 

Reusable filters can be washed with water in a sink or even a hosepipe but make sure it’s properly dry; otherwise, it may grow harmful bacteria!
