The Midiex C545 filter set is designed for easy maintenance and continued clean air in your living spaces. This 4-pack is compatible with Winix C545 and several related models, including B151, P150, and 9300, with part numbers 1712-0096-00 and 2522-0058-00.
Inside the pack you will find two true H13 HEPA filters paired with an activated carbon layer. This combination targets fine airborne particles while helping to manage odors and some everyday VOCs, offering a balanced approach to filtration that supports a healthier room environment.
How the filtration works
The H13 true HEPA elements capture a high percentage of particles as small as 0.3 microns, contributing to noticeably cleaner air during regular daily use.
- Two HEPA stages plus eight prefilters provide a layered defense against dust, pollen, pet dander, and other household irritants.
- The activated carbon layer helps minimize odors from cooking, smoke, and everyday household activities.
Maintenance tips and replacement timing
To keep your purifier performing optimally, replace the C545 filter every 5-10 months, depending on running hours and air quality. The 4-pack option lets you plan replacements ahead of time, ensuring fewer interruptions.
Proper fit and alignment are straightforward for most Winix units, and a fresh filter can help sustain efficient airflow and overall purifier effectiveness.
