The Ultimate Guide to Carbon Filter Air Purifier: What You Need to Know (May 2025 update)

If you're battling stubborn odours, smoke, or chemical fumes at home, an air purifier with carbon filter in the UK is your secret weapon. But not all carbon filters are created equal—some barely last weeks, while others (like those in Morris purifiers) keep your air fresh for months.

This guide cuts through the confusion, answering:

✔ Is a carbon filter good for an air purifier? (Spoiler: Essential for odours!)

✔ Carbon filter vs. HEPA: Do you need both?

✔ What are the disadvantages of carbon filters?

✔ Real-user results.

 

Why Choose an Air Purifier with Carbon Filter in the UK?

Carbon filters excel where HEPA filters can’t:

What Does a Carbon Filter Do?

✔ Eliminates odours: Cooking smells, pet accidents, smoke

✔ Traps chemicals: VOCs from paints, cleaners, and new furniture

✔ Works with HEPA: Combines particle + gas removal

 

Some facts:
● Prolonged exposure to VOCs can cause headaches and dizziness, or they can irritate the eyes, nose, and throat. In severe cases, long-term exposure to VOCs like benzene and formaldehyde has been linked to cancer.
● The study, "Modelling of an Air Cleaning Device With Activated Carbon Filter" revealed that an air purifier smoke remover fitted with a carbon filter significantly improves indoor air quality by reducing pollution from cigarette smoke.

"Our MOR-AP02 erased 2 years of dog smell in 48 hours. Guests now ask if we even have pets!" – Sarah, Manchester ⭐⭐⭐⭐⭐

Do Carbon Filters Eliminate All Smells?

● Not completely: A carbon filter may struggle to remove all odours over time, depending on its size and quality.

● Efficiency boost: HEPA air purifiers with multiple fan speeds can increase airflow, enhancing odour removal.

● Replacement needed: Regularly change the carbon filter to maintain efficiency.

Carbon Filter vs. HEPA: Do You Need Both?

What’s Better: A HEPA or Carbon Filter?

Filter Type	Best For	Limitations
HEPA (H13)	Dust, pollen, mould	Doesn’t remove odours
Carbon	Smoke, gases, chemicals	Doesn’t capture particles

 

Verdict: For complete air cleaning, you need both—Choose a carbon filter air purifier from the Morris collection.

 

Are Carbon Filters as Good as HEPA Filters?

HEPA filters are generally more effective than carbon filters for cleaning the air in your home. HEPA stands for High-Efficiency Particulate Air. These filters can capture tiny airborne particles as small as 0.3 microns.

Air pollutants are categorised into three types:

● PM10: Particles 10 microns or smaller.

● PM2.5: Particles 2.5 microns or smaller.

● PM1: Particles 1 micron or smaller.

 

HEPA filters can remove various pollutants, including:

● Large particles: human hair (70 microns), pet hair (60 microns), sand (50 microns), pet dander (25 microns).

● Smaller particles: dust (5 microns), cigarette smoke (2.5 microns), mould spores (2 microns).

 

Medical-grade HEPA filters can remove these pollutants with 99.95% efficiency.

However, HEPA filters do not effectively filter out volatile organic compounds (VOCs), which are responsible for unpleasant odours. For that, you still need a carbon filter.
