Enjoy fresh kitchen air, with our dual filter system.

Enjoy fresh air while cooking—even in recirculation mode. Our advanced dual filter system removes grease and odours: the metal filter captures coarse grease, while the Long-life Clean Air filter—an activated carbon filter—takes care of finer grease particles and odours.

Grease Filter.Our grease filters capture grease effectively, even during high-oil cooking. When saturated, they’re easy to clean—remove and place in the dishwasher. Included as standard with extractor hoods, with up to 17 mesh layers depending on model.

Exhaust or Recirculation Air Operation?

Exhaust Air Mode.Exhaust air mode (ducted) is effective for removing odours and grease, with full steam extraction. It expels air outside via ducts and replaces it with fresh air. Integrated grease filters are sufficient for operation. May not suit low-energy homes.

Recirculation Air Mode.Recirculation air mode (duct-free) filters odours and grease before returning purified air to the kitchen. A Recirculation Kit with Long-life Clean Air activated carbon filter is required. No external venting, so heated or cooled air stays inside.

Our Long-life Clean Air filter for recirculation.

Made to fit Bosch hoods perfectly, our Long-life Clean Air premium activated carbon filter features a large inner surface area that gently absorbs fine grease and even the strongest cooking odours.

Designed for optimised airflow, it supports steady extraction with remarkably low noise, so your kitchen always feels calm, fresh, and comfortably under control. Best of all, it has an impressive lifespan of up to four years, with a simple refresh function to keep it performing at its best. To run your hood in recirculation mode, you will just need a Recirculation Kit, which includes your filter. Discover more about how it works below.

Long-life Clean Air filter for Venting Hobs

A breath of fresh air, with added care.

Our Long-life Clean Air filter is tailored to fit your Bosch hood perfectly, working with its optimised airflow to extract quietly and steadily. Inside, a precise layer of activated carbon quickly absorbs strong cooking odours, even stubborn ones like fried fish.

For an extra touch of care, a biofunctional layer traps airborne pollen and neutralises allergens, making your kitchen a much more comfortable space for anyone with sensitivities.

Best of all, it keeps performing beautifully far longer than standard disposable filters. Instead of replacing it every year, you can simply refresh it in your oven up to three times, giving you up to four years of fresh air from a single filter.
