How to install
As a general guide: switch the hood off,
remove the metal grease filters, locate the filter housing, insert the
filter (and cage if applicable), and refit the grease filters.
Frequently asked questions
How do I know if my Nuvola Stratos hood uses recirculation mode?
The Nuvola Stratos are recirculation-only ceiling hoods — they do not
support external ducting. They always operate in recirculation mode and
always require a charcoal or ceramic filter when in use.
What is the difference between the charcoal and ceramic filter options?
Both achieve 85–90% odour reduction. The charcoal filter is a washable
active carbon panel replaced every 3–6 months. The ceramic filter lasts
up to 16× longer and is regenerated by heating in a domestic oven at
150–180°C for 1–2 hours rather than being washed or replaced on a
regular schedule. The ceramic filter is the higher upfront investment
but the lower long-term cost.
Can the ceramic filter be washed in the dishwasher?
No. The ceramic filter is regenerated in an oven — not washed. Follow
the oven regeneration instructions above. The charcoal filter option is
the dishwasher-safe alternative.
Do I need the cage housing?
If you are fitting a Number 16 filter for the first time, or if your
existing cage is damaged, select a filter option that includes the cage.
If you already have the metal cage housing fitted from a previous
installation, the filter-only option is all you need.
What happens if I don't replace or regenerate the filter?
A saturated or clogged filter stops absorbing odours effectively and
restricts airflow through the hood, reducing extraction performance.
Cooking smells will return to the kitchen and the motor may have to work
harder. Regular maintenance — either washing the charcoal filter or
regenerating the ceramic filter — maintains performance and protects
motor lifespan.
