Before you order.
Shipping, returns and fit work the same on every product.
Q01Will it fit my machine?
It's listed for C2401, RY4001, C2401010, and it replaces part numbers 2KE2105000, 2KE2110000, 2-KE2110-000. If your label shows a different model, compatibility isn't confirmed: email support@thinkcrucial.com with the model number before you order. If a listed model doesn't fit, we send a prepaid return label and refund you in full.
Q02Is this an original Hoover part?
No. It's an aftermarket filter made by Think Crucial to fit the models listed. Think Crucial is not affiliated with Hoover. We make what we sell.
Q03What if it doesn't fit, or I change my mind?
If it doesn't fit the model we list, we email a prepaid return label within 30 days of delivery and refund you in full; opened to test the fit is fine. Changed your mind? Return it unused in its original packaging within 30 days of delivery. The return label is free for these too.
Q04When will it arrive?
Shipping to U.S. addresses is free on every order. It ships from our fulfillment center in 1–3 business days and arrives in 3–7 business days.
Q05Is there a subscription?
No. You buy one when you need one. Nothing renews and nothing auto-ships.
We make what we sell.
Think Crucial started in 2007 at a family vacuum repair shop. Today we make aftermarket filters, bags and parts built to fit the machines you already own, plus our own descalers and cleaners. Most people can fit the part themselves. They just need the right one, and a way to check it first.

Bag & Filter for Hoover C2401 & Royal RY4001
Fits 3 Hoover models
$44.99Free U.S. shipping
Fit guaranteed: prepaid return label if it doesn't fit the model we list. 30-day returns.
Full product description
A reusable cloth dust bag plus a replacement filter for the Hoover Shoulder Vac Pro C2401 backpack vacuum. The bag replaces Hoover 2KE2105000 and the filter replaces Hoover 2KE2110000, the filter Hoover lists for the C2401.
What the filter adds
Our cloth-bag-only listing has just the bag. This kit adds the 2KE2110000 filter, so you can replace both worn parts in one order.
Which machines it fits
- Hoover C2401 and C2401010 (Shoulder Vac Pro): bag and filter both fit.
- Royal RY4001: bag and filter both fit.
- Royal RY4000: the bag fits, but the filter doesn't. The RY4000 uses Royal's 2KE0113700 filter, so RY4000 owners should buy the cloth bag on its own.
What's in the box
- 1 reusable cloth dust bag (replaces 2KE2105000)
- 1 filter (replaces 2KE2110000)
Does it include paper bags?
No. The C2401 also uses a disposable Type BP paper bag inside the cloth bag (Hoover 1KE2103000). Those are sold separately.
Is 2KE2105000 a filter?
No. 2KE2105000 is the cloth dust bag. The filter is 2KE2110000.
