In today’s world, where indoor air quality can significantly affect health and comfort, maintaining your HVAC system is more important than ever. At the heart of this system are your home air filters, which work silently to remove dust, allergens, and other airborne contaminants. But here’s the catch—these filters don’t last forever. So, the big question is: how often should you change your home air filters?
In this complete guide, we’ll explore the ideal frequency for changing your filters, factors that affect that schedule, and the signs that it’s time for a replacement. Plus, if you’re looking for professional air filter maintenance or cleaning solutions in Australia, Hygene Hood Cleaning has you covered.

What Do Home Air Filters Actually Do?
Home air filters are essential components of HVAC (Heating, Ventilation, and Air Conditioning) systems. Their primary function is to trap airborne particles, such as:
- Dust and dirt
- Pollen
- Pet dander
- Mould spores
- Bacteria and allergens
- Smoke and odours
By trapping these particles, air filters prevent them from circulating through your home, thereby protecting your HVAC system and improving your indoor air quality.
So, How Often Should You Change Your Home Air Filters?
There’s no one-size-fits-all answer. However, a general guideline is:
| Filter Type | Recommended Change Frequency |
| Fibreglass filters (basic) | Every 30 days |
| Pleated filters (standard) | Every 60–90 days |
| High-efficiency filters (HEPA) | Every 6–12 months (check specs) |
| Reusable filters (washable) | Clean every 30 days, replace yearly |
Still, this schedule can vary based on some key factors that we’ll discuss next.
Factors That Affect How Often You Should Change Your Filters
1. Type of Filter
Different filters have different capacities. Fibreglass filters are cheaper but need to be replaced more often. Pleated and HEPA filters last longer and are more efficient, but cost more.
2. Household Size and Occupancy
More people = more dust, hair, and dander circulating through the air. A large family home will likely require more frequent filter changes than a single-person household.
3. Pets in the Home
If you have pets, especially shedding animals like dogs or cats, expect your filters to clog up faster due to fur and dander.
Suggested schedule: Every 30–60 days with pets in the home.
4. Allergies or Respiratory Issues
If someone in your household suffers from asthma or allergies, you should change the filter more frequently to keep air allergens at a minimum.
Suggested schedule: Every 30–45 days for sensitive individuals.
5. Smoking Indoors
Smoking introduces tar, ash, and smoke particles into your home’s air, which can overload filters more quickly.
Suggested schedule: Every 30 days.
6. Local Air Quality and Climate
Living in a polluted city, bushfire-prone area, or a dusty rural environment can significantly impact how fast your filters become clogged.
Suggested schedule: Adjust based on environmental conditions—inspect monthly.
7. HVAC Usage
If you use your heating or air conditioning system daily, your filters will naturally collect more particles.
Suggested schedule: Every 1–2 months in high-usage seasons.
How to Know It’s Time to Change Your Air Filter
Aside from tracking time, here are some warning signs your Air Filter needs to be replaced:
✔ Dust build-up around vents
✔ Increased allergy symptoms or breathing issues
✔ Reduced airflow or HVAC inefficiency
✔ Noticeable odours from vents
✔ Higher energy bills
✔ Filter appears dirty or grey on inspection
If any of these sound familiar, it’s time to check or change your air filter immediately.
How to Change a Home Air Filter (Quick Guide)
Changing your filter is a simple process you can often do yourself:
Step 1: Turn Off Your HVAC System
Always power down the system before beginning any maintenance.
Step 2: Locate the Filter
Filters are typically located in the return air vent or within the HVAC unit itself.
Step 3: Remove the Old Filter
Slide it out carefully to avoid shaking loose any trapped particles.
Step 4: Check the Filter Size
You’ll find the size printed on the side of the filter—write it down or take a picture.
Step 5: Install the New Filter
Make sure the arrow on the frame points toward the airflow direction (usually into the system).
Step 6: Turn Your System Back On
Enjoy cleaner air and better performance immediately!
