That's for the C535 and the filters that OP posted are for the C545. They're not interchangeable, are they?

C535 uses filter A, C545 filter S. Not compatible, very different dimensions.

Costco has both filter A & S options on sale, 2 year set for $59.99. AMZN doesn't seem to have filter S.

You're right. I was going off the post title, which says 535. But the link takes you to 545 product.

If you use these, you missed out when they were $21.84 during the Prime Day sale. The Costco deal is luke warm since they're $80 plus whatever tax and then they subtract $20.

Anyone have issues with off-brand filters? This one is a third party.

Im sure that was a c535 deal out off brand c545. I've searched all 4 days and there were no deals on genuine c545 in Amazon.
