When's It DueHow often
How often should you replace a hoover filter or bag?
Bags when full; washable filters about every 3 months
A full bag or a clogged HEPA filter is why a vacuum suddenly smells and loses suction. Bags are use-based; many washable filters are due every few months.

Why replace it
Dust that bypasses a spent filter goes back into the room. That is the opposite of what you bought the machine for.
