A well-priced aftermarket Filter S set for the Winix C545 that includes enough carbon sheets to outlast the HEPA panels, making it the sensible default for that one model.

Overview
Colorfullife's replacement set for the Winix C545 air purifier includes two H13 True HEPA filters and eight activated carbon sheets. It substitutes for Winix Filter S, part numbers 1712-0096-00 and 2522-0058-00. The HEPA media is rated to capture 99.97 percent of particles down to 0.3 microns.
The carbon-to-HEPA ratio is the point of this kit. Eight carbon sheets against two HEPA filters lets you swap the odor-control layer several times over the life of each HEPA panel, which matches how the two media actually wear out at different rates. That is a more sensible packaging decision than a one-to-one pairing, and it is what makes the price per year work.
- Two H13 True HEPA filters plus eight carbon sheets
- Replaces Winix parts 1712-0096-00 and 2522-0058-00
- Individually sealed in plastic wrap
- FSC-certified filter paper
Who it's for
Built for Winix C545 owners specifically, and the compatibility list is narrow enough to matter. Kitchens, pet rooms and smoking households benefit most from having spare carbon sheets on hand. If you own a Winix 5500-2, C535 or a Sharp FP-P40CX, this is the wrong part.
Pros and cons
- Drops straight into the Winix C545
- Eight carbon sheets outlast the two HEPA panels
- H13 grade media rated to 0.3 microns
- Clearly cheaper than the branded Filter S
- Fits the C545 only, not other Winix models
- Carbon sheet quality has varied between production runs
- Does not trigger the purifier's own filter reset logic
Performance notes
Air passes the carbon sheet first, where it wraps the HEPA panel and adsorbs odor compounds, then the H13 media captures fine particulate. Carbon saturates far sooner than HEPA loads up, which is why replacing it separately every couple of months keeps odor control working without discarding an otherwise good HEPA panel. A loose or thin carbon wrap lets air bypass the media, so seating it properly matters more than it looks.

Frequently asked questions
Does this fit the Winix 5500-2 or C535?
No. The manufacturer states it is not compatible with the Winix 5500-2 (115115), the C535, or the Sharp FP-P40CX. It is made for the C545 only.
How many carbon sheets should I use at a time?
One carbon sheet pairs with the HEPA panel in the unit. The extras are there because carbon needs changing more often than the HEPA media does.
Is this a genuine Winix filter?
No, it is a Colorfullife aftermarket replacement for Winix Filter S, sold at a lower price than the branded part.
