Tornado HEPA Filter Cartridge K28893420

This is the genuine HEPA filter cartridge (part# K28893420) for the Tornado Strike TV190-W10-U and the Tornado Zephyr TV570-Q03-U. It is the final filtration stage, sitting after the fleece bag, and it is the part that decides what actually comes out of the machine’s exhaust.

Compatible Models for the HEPA Filter Cartridge

• Tornado Strike TV190-W10-U cordless upright vacuum
• Tornado Zephyr TV570-Q03-U cordless upright vacuum

This part is not exclusive to the Strike. Tacony’s parts records list part# K28893420 against two machines — the Strike TV190-W10-U and the Zephyr TV570-Q03-U — which is why the title carries the brand rather than a single model name. It is the same cartridge in both machines.

What the HEPA Filter Cartridge does

The fleece bag catches the bulk of what the machine picks up; the HEPA cartridge catches what the bag does not. In buildings where the vacuum runs during occupied hours — which is most of the reason to own a battery upright — that final stage is the difference between removing dust from a room and redistributing it. It also protects the suction motor from fine dust, which is the practical reason a machine run without one does not last as long.

Signs the HEPA Filter Cartridge needs replacing

Replace the cartridge on a schedule rather than waiting for a symptom, because a loaded HEPA does not announce itself the way a full bag does. The signs that you have left it too long are suction that is down with a fresh bag and a clear airway, a shorter run time from a full charge, and visible grey loading across the pleats. Any cartridge that is split, crushed at its seal, or has been wet should be replaced immediately.

Fitting the HEPA Filter Cartridge

Open the filter cover, lift the old cartridge out and get it straight into a bag rather than knocking it out — the point of the thing is that it is holding fine dust. Check the seating face is clean, fit the new cartridge squarely so it seals all the way round, and confirm the filter cover closes without being forced. A cover that will not close easily usually means the cartridge is not seated.

Frequently Asked Questions

How often should the HEPA cartridge be changed?

It depends on hours and how dusty the work is, but it should be on a schedule rather than on symptoms. A loaded cartridge costs you suction and battery run time long before it looks obviously full.

Can I wash or tap out the cartridge and re-use it?

No. Washing destroys the media and tapping it out releases exactly the fine dust it was fitted to capture. It is a replacement item.

Do I still need one if I always use fleece bags?

Yes. The bag and the cartridge are two stages doing different jobs. Running without the cartridge lets fine dust reach the motor and leave the machine with the exhaust.
