Our review of the 2 Pack C545 HEPA Replacement Filter S finds it best for Winix C545 owners who want a lower-cost, plug-and-play alternative to OEM filters. The main reason to buy is straightforward: it provides a perfect fit for the Winix C545 model and combines a certified HEPA element with multiple activated carbon pads so users get both particle capture and odor control without paying OEM premiums. Installation is simple and replacement cadence is clear, so this is a practical choice for routine home air maintenance.

Key Features

• Perfect fit: Designed to match Winix C545 filter S dimensions and replaces part numbers 1712-0096-00 and 2522-0058-00 so it installs without modification.
• HEPA performance: The HEPA element captures 99.97% of airborne particles down to 0.3 microns, improving indoor air quality for allergy sufferers and general use.
• Activated carbon supply: Each pack includes multiple activated carbon filters that help reduce household odors and provide extra replacement pads.
• Easy maintenance: The HEPA filter has a pull-tab for straightforward removal and guidance recommends replacing HEPA every 6-8 months and carbon every 3 months.
• Cost-effective packaging: Components are sealed in plastic wrap and offered as a multi-piece set to lower the per-change cost compared with single OEM units.

Who It's For

This replacement set is ideal for owners of the Winix C545 air purifier who want a direct-fit, economical alternative to brand-name filters and who perform regular maintenance. It suits households looking to control dust, pet dander and common household odors without spending on OEM-branded packs.

People who should look elsewhere include owners of different Winix models such as the 5500-2 or the C535, and anyone using air purifiers from other brands listed as incompatible, since the filter will not fit those units.
