The bottom line: this pair of one-year replacement filters delivers the expected True HEPA filtration and carbon odor control so users can restore original airflow and maintain air quality with minimal fuss. Installation is straightforward and the filters are designed to match the manufacturer specifications, making them a practical choice for those focused on consistent performance over time.

Key Features

• One-year replacement sets: Each package contains the H filter for the 5500-2 and the T filter for the HR900, sized for an annual change cycle for steady performance.
• True HEPA efficiency: The HEPA element captures 99.97% of particles down to 0.3 microns, improving removal of dust, pollen, and fine particulates.
• Advanced odor control carbon: The AOC carbon layer reduces VOCs, fumes, and household odors for noticeably fresher air.

Who It's For

This replacement filter set is best for owners of the Winix 5500-2 and Winix HR900 who want to maintain the original performance of their units and prefer genuine factory parts. It suits households prioritizing allergy relief, odor reduction, or consistent particulate removal on an annual maintenance schedule.

Users who run their purifiers intermittently or in very small rooms will still benefit, but those seeking higher-frequency replacement schedules for heavy-smoke environments or professional air quality control may need to change filters more often than the recommended 12 months.
