Remanufactured Ink & Toner Cartridges

Q: What is the difference between compatible, remanufactured, and OEM cartridges?

OEM cartridges are made by the printer manufacturer. Remanufactured cartridges reuse genuine OEM shells that have been cleaned, refilled, and tested. Compatible cartridges are newly built third-party cartridges engineered to the same specifications. Both options typically cost 30 to 70 percent less than OEM.

Customer Testimonials

Thank you for your excellent service. I ordered ink cartridges for my OLD printer. I have been wary of "compatible" cartridges, as those I ordered from another online store did not fit my printer - though the order said they were compatible. But it is getting increasingly difficult to find cartridges for this printer. Castleink provided the correct cartridges at a very reasonable price and they arrived in just a few days - without premium shipping costs. I'll definitely be ordering from you again.
Marcy, Illinois

Being a middle aged woman, I'm skeptical ordering over the internet. I priced ink at the local stores and your prices were so low, I just had to try your site. I'm am so impressed with the quality and speed with which I received my order. I am forwarding your site to all my computer friends. It's nice to save time and money these days.
Effie, Boston

I have two different printers that I am constantly having to refill because I print a lot. The problem that I was running into is because I print so much, it was just so expensive to have to buy refills for both printers' inkjet cartridges for the Epson and then, of course, laser toner for the Brother. Castle Ink's shipping is fast, customer service is excellent, and the product that they sell is superb. I have not had one single problem from any of the refills I have gotten from Castle Ink.
Brian, NY

Just a note to thank you for being there, and saving me money on ink. The cartridges I received from you are working just fine. Thank you again.

Frequently Asked Questions About Compatible Ink & Toner

Are compatible ink cartridges safe for my printer?

Yes. Castle Ink's compatible and remanufactured cartridges are tested to meet the same print performance and page-yield specifications as the original equipment manufacturer (OEM) cartridges they replace. Every cartridge is backed by a 365-day money-back guarantee.

Will using compatible cartridges void my printer warranty?

No. Under the U.S. Magnuson-Moss Warranty Act, a printer manufacturer cannot void your warranty solely because you use a third-party ink or toner cartridge. A warranty can only be voided if the non-OEM cartridge is shown to have caused specific damage.

What is the difference between compatible, remanufactured, and OEM cartridges?

OEM cartridges are made by the printer manufacturer (HP, Canon, Epson, etc.). Remanufactured cartridges reuse genuine OEM shells that have been cleaned, refilled, and tested. Compatible cartridges are newly built third-party cartridges engineered to the same specifications. Both compatible and remanufactured cartridges typically cost 30–70% less than OEM.

How do I find the right cartridge for my printer?

Enter your printer model number or cartridge number in the search bar at the top of any page. You can also browse by brand — HP, Canon, Epson, Brother, Lexmark, Dell, Xerox, and others. If you are unsure, contact our U.S.-based support team for help identifying the correct replacement.

How fast does Castle Ink ship?

Orders placed before 1:00 PM Eastern Time on business days ship the same day from the United States. Free shipping is available on qualifying orders.

What is your return policy?

Castle Ink offers a 100% satisfaction guarantee. If a cartridge does not work properly with your printer, we will replace it or provide a full refund within 365 days of delivery.

Are remanufactured cartridges environmentally friendly?

Yes. Each remanufactured cartridge reuses an original OEM shell that would otherwise become plastic waste. Choosing remanufactured ink and toner reduces landfill plastic and lowers the energy required to produce a new cartridge.

Happy surprise

I was prepared to accept lower quality because of the lower price but I was happily surprised when I got excellent printing and the cartridges last SO much longer! I am very impressed 👏
