If your Hoover WindTunnel bagless canister has started pushing dusty-smelling air or losing suction, the final HEPA exhaust filter is usually the culprit. This genuine Hoover S3765 final HEPA exhaust filter is the maintenance part that keeps fine dust, pollen, and pet dander locked inside the vacuum instead of blowing back into your room. It is the right fix for allergy- and asthma-conscious households, pet owners, and anyone who wants their older WindTunnel canister to clean and smell like new again rather than replacing the whole machine.
As the last stage of filtration, the final exhaust filter handles the air your vacuum returns to the room, so its condition directly affects how clean that air feels. Over months of use the pleated media gradually loads with fine particles, which is what causes the tired, dusty smell and the slow drop in airflow many owners notice. Because this is a wear part rather than a defect, a simple swap restores the canister to like-new exhaust performance for a fraction of the cost of a new vacuum. It installs in seconds with no tools, dropping into the retainer on the side of the canister.

Frequently asked questions
Which Hoover vacuums does this filter fit?
It fits the Hoover bagless WindTunnel canister series, including the S3755 and S3765 and their variants such as S3755045, S3765040, and S3755080. It sits inside the retainer on the side of the canister.
How often should I replace the HEPA exhaust filter?
Replace it at least twice a year for typical use. If anyone in your home has severe allergies or asthma, replacing it every three months helps keep exhaust air as clean as possible.
Is this a washable filter?
No. This is a pleated HEPA exhaust filter and should be replaced, not washed. Washing damages the media and reduces filtration. Swapping in a fresh filter restores full performance.
Will a new filter help with vacuum smell and suction?
Often, yes. A clogged exhaust filter restricts airflow and can let dusty odors pass through. Installing a fresh HEPA filter helps recover airflow and keeps fine particles trapped instead of recirculating.

Yes. This is the Hoover OEM final HEPA exhaust filter, part number 59134050, sold by an authorized dealer.
