Replacement cassette filter for the Momo J-404 built-in dust extractor. It catches the fine particles produced when filing, not just the visible filings, so the air leaving the unit is genuinely cleaner rather than merely moved.
Technical data

Good to know
Airflow falls gradually as the cassette fills, slowly enough to miss. If the extractor feels weaker than it did, check the filter before suspecting the fan.
