EVERYTHING YOU NEED TO KNOW ABOUT
Activated Carbon Filters
What Activated Carbon Filters Actually Do for Your Air Purifier
HEPA filtration helps reduce airborne particles. Activated carbon helps address the odors¹ and gases that traditional particle filters are not designed to remove. PuroAir air purifiers include HEPA and activated carbon filtration for a complete indoor air cleaning system.
Why Activated Carbon Matters Indoors
Clean Air Isn't Just About What You Can See
Many indoor air concerns are invisible. While dust³ and particles may be noticeable, odors¹ and gases from everyday activities can also affect how your home feels.
Cooking
Strong kitchen odors¹ from frying, grilling, and everyday meals can linger throughout your home.
Pets
Pets bring companionship, and sometimes unwanted odors¹ from fur, bedding, and everyday messes.
Household Products
Paints, cleaners, furniture, and building materials can release VOCs⁵ into indoor air.
Smoke¹ & Lingering Odors¹
Smoke¹ odors¹ can attach to fabrics, furniture, and surfaces, creating persistent smells.
What Is an Activated Carbon Filter?
A Smarter Way to Help Reduce Household Odors¹
Activated carbon is a highly porous material designed to adsorb certain gases and odor¹-causing molecules.
Unlike HEPA filters, which are designed to reduce airborne particles, activated carbon works differently by filtering certain gases and compounds within its porous surface.
Together in your PuroAir air purifier, the three layers provide a more complete approach to indoor air filtration.
Simple Explanation of the 3 Filter Layers
Activated Carbon Filter
Helps reduce odors¹ and certain gaseous pollutants.
HEPA Filter
Reduces airborne particles like dust³, pollen⁴, and fine particles.
Pre-Filter
Filters larger particles, such as dust³ and pet hair, helping to extend the life of the additional filters.
THE POWER WITHIN
What Is CarbonTech™?
CarbonTech™ is PuroAir’s proprietary blend of activated carbon, engineered to filter and reduce household odors¹, smoke¹, and certain gases from the air.
Unlike particle filters that are designed to filter airborne particles, activated carbon works differently. Its highly porous structure provides a large surface area where certain odor¹-causing compounds and gases can be filtered as air passes through the filter.
CarbonTech™ combines the odor¹-fighting benefits of activated carbon with PuroAir air purifier filtration technology to help create cleaner, fresher-smelling indoor air.

Frequently Asked Questions
What does activated carbon do in an air purifier?
Activated carbon helps reduce odors¹ and certain gaseous pollutants by adsorbing odor¹-causing molecules and gases as air passes through the filter.
Is activated carbon better than HEPA?
Activated carbon and HEPA filters serve different purposes. HEPA filters are designed for airborne particles, while activated carbon helps address odors and gases. Many advanced air purifiers, like PuroAir, combine both technologies.
Does activated carbon filter smoke odors?
Activated carbon can help reduce many smoke¹-related odors¹ by filtering certain odor¹-causing molecules. For wildfire smoke¹ concerns, HEPA filtration is also important because smoke¹ contains fine particles.
How often should I replace my PuroAir filter?
We recommend replacing your HEPA filter with activated carbon every 3–4 months, or when the filter life indicator alert is enabled. Regular replacement helps maintain filtration performance.
