APPLIANCEMATES Replacement Filter A 115115 4-Pack - HEPA + Carbon

In this review the APPLIANCEMATES Upgraded 4 Pack Replacement Filter A 115115 is judged on fit, filtration and value for households that need a straightforward replacement for select Winix-compatible purifiers. The bottom line: this kit is for owners who want an affordable way to restore a purifier's particle and odor control without buying brand-name cartridges. It includes two H13-grade True HEPA filters and eight activated carbon pre-filters sized to match the original, making installation quick and performance comparable for routine home use.

Key Features

• Perfect compatibility: Precisely sized to replace Filter A 115115 and fit models such as C535, 5300-2, P300 and several WAC and 5000 series machines for a direct swap.
• Two-stage filtration: Each unit combines an H13-grade True HEPA layer with a high-efficiency activated carbon pre-filter to capture particles and reduce odors.
• Complete kit: The 4-pack provides two HEPA filters plus eight disposable carbon pre-filters so users can stay stocked for regular maintenance cycles.
• Easy maintenance: Carbon pre-filters attach to the frame and the HEPA element drops into the cleaner with no tools required for fast replacement.
• Replacement schedule: Manufacturer guidance included - change the HEPA once a year and carbon pre-filters every three months to keep output consistent.

Who It's For

This replacement set is best for homeowners with compatible Winix-style purifiers who want a cost-effective, ready-to-install alternative to factory cartridges. It is particularly useful for families with pets, kitchens open to living spaces, or light smokers because the activated carbon helps control smells while the HEPA captures dust and hair.

People who need filters for Model C545 should look elsewhere, since this HEPA does not fit that model. Also, buyers seeking a reusable or industrial-grade filter system may prefer a different product; this kit is designed as disposable, periodic replacements rather than a lifetime solution.

Pros & Cons

Pros

• Good fit and easy installation makes filter swaps quick and tool-free.
• Includes both True HEPA and activated carbon stages for particles and odors.
• Value pack supplies multiple carbon pre-filters so routine replacements are covered.

Cons

• Some users report mixed durability of the carbon layer, with occasional shedding or breakdown over time.
