Hoover T-Series Primary Rinsable Filter (303173002)
A reusable genuine filter for Hoover T-Series uprights; buy two so one can dry.
The short version
- Owners of a Hoover WindTunnel T-Series upright vacuum
- Anyone who wants a spare so one filter can dry while the other is in use
- People with a worn or torn primary filter
- Your Hoover is not a T-Series model; other Hoover lines use different primary filters
- Your filter is intact and only needs a rinse
What owners like
- Reusable after a rinse, which keeps running costs low
- A hands-on review of a T-Series vacuum reported no suction loss with the filters kept clean
Common complaints
- A rinsed filter needs up to a full day to dry, which leaves the vacuum idle without a spare
- Hair and debris can collect in the bagless dirt cup around the filter area, so it needs regular attention
Based on Hoover's parts page, the Hoover WindTunnel UH70120 owner's manual, two vacuum parts retailers, and a hands-on review of the T-Series Rewind on Vacuum Wizard. Owner feedback on the filter itself was thin..

What it does
A genuine Hoover washable primary filter for WindTunnel T-Series upright vacuums, now sold as part 303173002, which replaces the original part 303173001.
- Genuine Hoover part for the WindTunnel T-Series upright line
- Sits in the dirt cup and pulls out by a tab
- Rinsable under running water, so it can be reused rather than replaced
- Works alongside a separate HEPA exhaust filter, which Hoover says must not be rinsed
- Current part 303173002 supersedes the older 303173001 number printed in many manuals
A sensible spare for anyone who owns a Hoover WindTunnel T-Series upright, since the filter can be rinsed and reused instead of thrown out. The main trade-off is drying time: Hoover says a rinsed filter can take up to 24 hours to dry, so a second filter lets the vacuum stay in use. Check the model number on your vacuum first, because Hoover only says it fits T-Series uprights.
