When it comes to protecting your indoor air quality, choosing the right filter type makes all the difference. Two of the most common filtration systems found in air purifiers are HEPA filters and carbon filters—but they serve very different purposes. Here's what you need to know before deciding which suits your home best.
What Is a HEPA Filter?
A HEPA (High Efficiency Particulate Air) filter is designed to remove microscopic airborne particles from the air. These include:
-
Dust and dust mites
-
Pollen
-
Pet dander
-
Mould spores
-
Bacteria and some viruses
Wquipped with a HEPA 13 medical-grade filter, AirDry Pro traps up to 99.95% of ultra-fine particles, as small as 0.1 microns, making it highly effective for allergy sufferers, households with pets, or anyone seeking cleaner air.
What Is a Carbon Filter?
Activated carbon filters are specialised for removing gases, odours, and volatile organic compounds (VOCs). Rather than capturing particles, they absorb pollutants such as:
-
Cooking smells
-
Cigarette smoke
-
Chemical fumes
-
Pet odours
They are ideal for those sensitive to smells or living near high-traffic areas where air pollutants from outside may linger.
Key Differences at a Glance
| Feature | HEPA Filter | Carbon Filter |
|---|---|---|
| Removes Dust & Allergens | ✅ Yes | ❌ No |
| Traps Gases & Odours | ❌ No | ✅ Yes |
| Ideal for Allergy Sufferers | ✅ Yes | ❌ No |
| Removes Pet Dander | ✅ Yes | ✅ Yes (limited) |
| Main Function | Particle Filtration | Odour/Gas Absorption |
Which Should You Choose?
If your main concern is airborne particles—such as dust, allergens, or fine pollutants—a HEPA filter is the clear choice. This is especially true for households with children, elderly family members, or anyone prone to allergies or asthma.
If your primary goal is to eliminate unpleasant smells or reduce exposure to gases, a carbon filter will be more suitable.
Why AirDry Pro Stands Out
The AirDry Pro 25L is engineered with a HEPA 13 medical-grade filter, delivering exceptional protection by removing 99.95% of airborne particles from your environment. Unlike typical purifiers, AirDry Pro goes beyond just filtering—it also includes:
-
Dehumidification mode to fight mould and damp
-
Laundry drying mode to speed up indoor drying
-
Negative ion technology for fresher air
-
Smart control features for everyday convenience
It’s a reliable, powerful solution for anyone prioritising clean, particle-free air.
Final Thoughts
When choosing between HEPA and carbon filters, the decision depends on your specific air concerns. For health-focused air purification, a HEPA filter—especially HEPA 13 like in the AirDry Pro—is the superior choice. It targets what you can’t see but definitely don’t want to breathe.
