Depending on the type of activated carbon filter you have, you can tell if it can be cleaned:
Standard filters: These are the most traditional filters and have a lifespan of 6 months before they need to be replaced. These filters cannot be cleaned; once they are saturated, they must be replaced.
Long-life filters: These filters have a long lifespan of about 3 years, but they are not permanent and need to be regenerated regularly. The filters must be regenerated every 3 months, and you need to follow 6 specific steps to avoid damaging them.
So for standard filters the answer is no, and for regenerable long-life filters the answer is yes, but you need to take the right precautions. The lifespan of the filter may also vary depending on how long the range hood itself has been in use.
In the filter hood, there are usually two different filters: the first is the grease filter, while the second (located deeper) is the activated carbon filter. The grease filter must be cleaned regularly, either by hand or in the dishwasher.
