Hoover F79 Exhaust Filter

This filter is specifically designed for Hoover upright models UD70250 and AD40079. Please check the model number on your vacuum's rating label—usually found on the back or bottom of the unit—to ensure it matches before purchasing.

No, this is a non-washable, single-use filter. Once it becomes clogged with dust and debris, it should be replaced to maintain your vacuum's suction power and air filtration efficiency.

The round, pleated design increases the surface area of the filter material. This allows it to trap more fine dust particles and allergens while still maintaining proper airflow through your vacuum.

While replacement frequency depends on how often you vacuum and the amount of debris in your home, a general rule of thumb is to replace the filter every 6 to 12 months. If you notice a drop in suction or a musty odor while vacuuming, it is likely time for a fresh one.

Using a saturated filter restricts airflow, which forces the vacuum motor to work harder and can lead to overheating or reduced suction performance. Additionally, a clogged filter will no longer effectively trap allergens, allowing dust to recirculate back into your home's air.
