It's listed for 12 models, from M084500V to UD40230, and it replaces part numbers EP604, EU18410.

If a listed model doesn't fit, we send a prepaid return label and refund you in full.
Q02Is this an original Shark part?
No. It's an aftermarket filter made by Think Crucial to fit the models listed. Think Crucial is not affiliated with Shark. 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 the same business day when you order by 2pm ET, and arrives in 2–5 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.
