Luxair DWN Long-Life Matt Filter — Number 12
If your Luxair DWN cooker hood runs in recirculation mode, this is a fundamentally different type of charcoal filter from the standard granular carbon replacements. The Number 12 is a long-life matt filter designed to be washed and reused — lasting up to 3 years with correct maintenance, rather than being replaced every 3–4 months. One purchase covers you for years rather than months.
Compatible hoods include:
Important: The DWN model requires 2 filters — one fitted behind each metal grease filter. Each pack contains 2 filters, providing exactly what you need for a complete installation. The metal grease filter is not included — see related products for the correct grease filter for your hood.
If you're unsure whether this is the correct filter for your hood, check your hood's manual or use the contact form on this page — our UK-based support team will confirm for you.
Washable and reusable — how it works
Unlike standard granular carbon charcoal filters which are discarded once saturated, the Number 12 matt filter uses regenerated washable panels that can be cleaned and reinstated to full performance. Clean the filter every 4 months — or every 3 months if you cook heavily — and it will continue performing effectively for up to 3 years and up to 5 wash cycles in total.
To clean: either wash by hand using warm soapy water, or place flat in the dishwasher on a low-temperature cycle. After washing, allow to air dry vertically at room temperature before refitting. Do not tumble dry or use heat to speed drying.
Why choose the long-life filter over standard replacements
The Number 12 is the more sustainable and cost-effective choice for downdraft hood owners who want to reduce ongoing maintenance costs and filter waste. Rather than purchasing replacement packs every 3–4 months, a single pack provides up to 3 years of filtration with straightforward periodic washing. It is also the environmentally preferable option — manufactured with regenerated and washable panels to minimise waste.
How to install
A short installation video is available on this page — watch it before fitting for a clear visual walkthrough. As a general guide: switch the hood off, remove the metal grease filters, locate the filter housing behind each grease filter, fit one Number 12 filter per side, and refit the grease filters.
Frequently asked questions
How do I know if my downdraft hood uses recirculation mode?
If your downdraft hood vents air externally through ducting to an outside wall or under the floor, it is ducted and does not require charcoal filters. If it has no external duct and returns filtered air back into the kitchen through a plinth grille, it is recirculating and requires charcoal filters.
Can I wash this filter in the dishwasher?
Yes — place the filter flat in the dishwasher on a low-temperature cycle. Alternatively, wash by hand in warm soapy water. After washing, allow to air dry vertically at room temperature before refitting. Do not use heat to speed up drying.
How many times can I wash the Number 12 filter?
Up to 5 wash cycles over the filter's lifespan of up to 3 years. After 5 washes, the filter should be replaced — performance will diminish beyond this point regardless of how it looks.
Is this the same as the standard Number 11 downdraft filter?
No. The Number 11 is a standard granular carbon filter that is discarded after 3–4 months of use. The Number 12 is a long-life washable matt filter designed to last up to 3 years with regular cleaning. Both are for the 90cm Downdraft Hood in recirculation mode.
How many filters does my downdraft hood need?
The downdraft hood requires 2 filters — one behind each metal grease filter. Each Number 12 pack contains 2 filters.
Is the metal grease filter included?
No. The metal grease filter is sold separately — see the related products on this page for the correct grease filter for your hood.
Does the subscription auto-renew?
Yes — the subscription renews automatically. You can skip, pause, or cancel at any time. Full details are in our subscription policy.
