Confused on purchase of ARC for my Pixma MG6821 and TS 6020

[fdm2000]

Researching refillable ARC carts and need help to determine if all CLi271 and PGi 270 cartridges are the same and will work in all Canon printers that use these cartridges. Some sellers of the refillable ARC CLi270 and PGi 270 specify specific Canon printer models or state their carts will work with certain printer models - many of these sellers do not mention my Canon models.
Hope someone can shed some light on this question.

The only way to be really sure is to take a plunge and try it out directly. That said you could try contacting someone at InkOwl as they do supply ARC equipped refillables for that series of cartridge in the North American market (which the 270/271 is part of).
