Why AC Filters Need to Be Changed
AC filters must be changed often because they collect dust, dirt, and other particles that can damage the AC unit.
Over time, this accumulation will cause the AC filter to become less effective at cooling your home, meaning you’ll have to run the AC unit for longer periods to achieve the same level of comfort. And that’s bad news for your energy bill and the environment.
The good news is that changing the AC filter and aircon servicing is a relatively easy task, and it only needs to be done once a month or so, depending on how often you use your AC unit.
How Often to Change AC Filters
Changing your air filter is important in keeping your air conditioning unit running efficiently. It’s also one of the easiest DIY projects to save money on your energy bills.
How often to change AC filters depends on what type of filter you have, how many people live in your home and how much time has passed since the last time you changed it.
Here are some basic guidelines:
For everyday use: Change filters monthly or every three months. This will keep dust, pollen, and pet dander from entering your home through the ductwork. It will also help reduce allergies for those who suffer from them.
To keep pets from shedding fur: Every three months or more often if necessary.
If there are smokers in your home: More frequently — every two weeks or so — until they stop smoking; then back off to monthly or quarterly intervals as needed to keep dust and smoke particles out of the air.
Changing your air conditioner filters regularly is necessary to keep your system working as efficiently as possible. It also helps keep allergens out of the air you breathe and your home.
The frequency at which you should change your air filter depends on several factors. First, consider the size of your HVAC unit and the number of people in your home. If you have a small unit or live alone, changing filters once every three months may be sufficient.
However, if you have a larger unit or live with more people, then it could be beneficial to change them more frequently than that.
You should also consider how dusty or dirty the air is where you live.
For example, if you live in an area like Singapore where there are lots of pollution particles floating around in the air, then replacing your filter, more often than not, will be beneficial to keeping those particles out of your lungs while reducing energy costs by keeping them from clogging up your AC unit’s cooling coils.
Pleated air filters can last up to six months.
If you’re using pleated air filters, they can last anywhere from three to six months. But it depends on the pollution level in your area and how often your AC is running.
If you’re in a high-traffic area, your filters must be changed more often. And if you have pets or allergies, you’ll also want to change your filters more often.
But here’s the thing: it’s always better to change your filters sooner rather than later. You don’t want to wait until they’re completely clogged up, and your home’s air quality has worsened.
Tips for Changing AC Filters
It’s important to change your AirCon filters regularly. How often should you do it? Well, that depends on various factors, including the type of filter you’re using, the size of your home, and how often your AC is used.
Here are some general guidelines to help you get started:
- If you have a disposable filter, change it every month.
- If you have a reusable filter, clean it every two to four weeks.
- If you have a high-efficiency particulate air (HEPA) filter, change it every six months.
Of course, you should always check the manufacturer’s instructions to ensure you follow the correct guidelines.
Most filters should be serviced every six months, although this may vary depending on the type of filter and the environment it’s used in. Speak to a professional to find the best schedule for servicing your AC filters.
