Thank you for your review — we truly appreciate your feedback. We're glad to hear the filter is working well!

Our filters do not include O-rings, as there are many different housing manufacturers and a wide variety of O-ring sizes. Because of this, we’re unable to guarantee that we could provide you with the correct one.

If you need a replacement O-ring, we recommend bringing your old one to a local hardware store to match it accurately and ensure you're purchasing the correct size.

Thanks again for your support — we're happy to have you as a customer and look forward to serving you again!
