When is it time to replace air conditioning filters?
Not all filters are the same: some are washable and reusable, while others, even the most robust ones, require periodic replacement, as often recommended by the manufacturer itself. It is time to replace them when:
They are visibly damaged and have tears, deformations or breaks in the filter mesh;
After cleaning, they are still obstructed or do not allow air to pass through properly;
There is a persistent bad smell or traces of mould even after cleaning.
In general, replacement every 6-12 months is recommended for disposable filters, but the frequency may vary depending on use.
