Here is info copy and pasted from Google:
The Winix C545 uses Size S filters (approx. 11 x 13.25 inches), while the Winix C535 uses Size 21/Filter A (approx. 12.6 x 16.3 inches). The C535 filter is significantly larger in surface area, and they are not interchangeable. [1, 2, 3]
Winix C545 (Size S / 1712-0096-00)
• Dimensions: H: 13.1" x L: 10.9" x W: 1"
• Fitment: Typically sold at Costco, uses a smaller filter area, often referred to as "Filter S".
• Carbon Filters: Often requires 4 charcoal pre-filters, changed every 3 months. [1, 3, 4, 5]
Winix C535 (Size 21 / 115115 / Filter A)
• Dimensions: H: 16.34" x L: 12.60" x W: 1.18"
• Fitment: Compatible with 5300, 6300, 5300-2, and P300.
• Carbon Filters: Uses a larger, thicker filter assembly. [2, 6]
Key Takeaway:Ensure you purchase the correct filter by model number. The C545 uses Filter S and the C535 uses Filter A/21. The C535 filter is larger and incompatible with the C545. [2, 3, 7, 9]

Costco carried C535, then C545, and now the round one, C610. For the genuine Winix filters, Amazon has a better price for C535 (Size A) filters, $26 a set.
