Serious odour and VOC control for your Smart Air SA700. Each filter contains 750g of granular activated carbon, 1.5kg in total when both are installed, which is more real carbon than any other purifier setup we sell. Activated carbon adsorbs gases that HEPA filters can't touch: VOCs from paint, new furniture and cleaning products, plus cooking smells, pet odours and woodsmoke. The carbon filters fit behind the SA700's HEPA filters on both sides and can be added or removed any time. Sold as a pack of two.

How long does a carbon filter last?

There is no single replacement interval. Carbon filter life varies massively and depends on the type and amount of gases and odours it encounters, how often you run the purifier and how much activated carbon the filter contains.

How do I know when to replace it?

Smart Air recommends a smell test every 1–2 weeks to help judge when your carbon filters need replacing.

  1. Switch off and unplug your purifier, then remove the carbon filters.
  2. Hold the centre of each filter near your nose and gently check for an unpleasant smell.
  3. If a filter smells sour, acidic or chemical, Smart Air recommends replacing it.

Also consider replacing the carbon filters if they no longer reduce the odour you bought them for. Colour and dust build-up do not tell you how much gas-filtering capacity remains, and removing surface dust does not restore that capacity.

The smell test is a practical maintenance guide. An absence of smell does not confirm that all gases have been removed.

What affects filter life?

Activated carbon has a limited capacity. Higher concentrations and frequent exposure can use that capacity more quickly. The type of gas, humidity, airflow and amount of carbon also affect performance, so a replacement schedule that suits one home may not suit another.

Looking after your carbon filter

Switch off and unplug the SA700 before inspecting or cleaning it. Keep the air inlets and outlets clear, and wipe the purifier body with a dry cloth.

Do not wash or soak the carbon or particle filters. Removing surface dust does not restore the carbon’s capacity to capture gases and odours.

Follow the SA700 manual when removing and refitting the filters. Secure the filter clamps and screws before restarting the purifier.

Fitting a replacement

Switch off and unplug your purifier before replacing its filters. Remove any protective packaging from the new filter and follow your model’s manual for the correct position and orientation.

Check the HEPA filter separately. Replacing the carbon filter does not automatically mean both filters need changing.

Small pores. A different job.

A separate layer for everyday odours.

Cooking, pets and everyday household products can introduce odours and gases into your indoor air. Activated carbon helps reduce some of these as air passes through the filter.

Its microscopic pores create a large internal surface where certain gas and odour molecules stick. This process is called adsorption.

Where can carbon help?

Choose a concern to explore

Cooking odours

Carbon can help reduce lingering cooking smells as air passes through the filter. Use your extractor fan and ventilation to remove pollution at its source. HEPA handles the airborne particles produced during cooking.

Pet odours

Carbon can help with some everyday pet odours. Regular cleaning and dealing with the source still matter, while HEPA captures airborne pet dander and other particles.

Smoky smells

Smoke contains both particles and gases. HEPA captures the particle component; activated carbon can help with some associated odours and gases. Performance depends on exposure and remaining carbon capacity.

Household VOCs

Some cleaning products, furnishings and other household materials release volatile organic compounds, or VOCs. Activated carbon can adsorb certain VOCs, but effectiveness varies by substance and conditions.

Carbon works alongside ventilation and reducing pollution at its source. It does not remove every gas. These filters are not designed to remove carbon dioxide or provide protection from carbon monoxide.

FAQs

No. They do different jobs. HEPA captures airborne particles, while activated carbon helps with certain gases and odours. Use the carbon filter alongside the matching HEPA filter according to your purifier’s manual.

No. Check each separately and replace it when needed. The carbon filter can reach capacity while the HEPA filter still has useful life remaining, or vice versa.

Do not wash it. Treat it as a replaceable filter and follow the manufacturer’s care instructions. Airing or sunlight should not be relied on to restore its original capacity.

Yes. These carbon filters fit the SA700 alongside either its E11 or H14 particle filters.

Fit one carbon filter on each side. Install the particle filter first, then the carbon filter on the outside, following the direction markings and your SA700 manual. Secure the filter clamps and screws before use.

This pack contains two carbon filters only. The purifier and particle filters are sold separately.
