Which Winix C535 replacement filter set fits your needs?
The genuine Winix set is the clearest choice if you want the brand's own replacement, while compatible 115115 sets vary in pack size and carbon filter contents. The C545 Filter S picks below are for C545 owners and do not fit the C535.
Genuine Winix 115115 Replacement Filter: Best for a genuine replacement set
- Made for Winix C535
- True HEPA filter and 4 carbon filters
- Winix recommends HEPA replacement every 12 months and carbon replacement every 3 months
The genuine Winix set is made for the C535 and includes a True HEPA filter with 4 carbon filters. Winix recommends different replacement intervals for the HEPA and carbon filters.
Pros
- Genuine Winix filter set
- C535 compatibility is stated
- Separate guidance for HEPA and carbon replacement
Cons
- HEPA and carbon filters have different replacement intervals
The Genuine Winix 115115 set is made for the C535, along with several other Winix models. It contains one True HEPA filter and 4 carbon filters, giving you both main-filter and odor-filter replacements in one set.
Winix recommends replacing the True HEPA filter every 12 months and the carbon filter every 3 months. The unit also has a check filter indicator, which gives you a reminder to inspect the filter set.
The brand describes the HEPA filter as capturing airborne allergens, including pollen, dust, smoke and pet dander. Its carbon filter is designed to reduce VOCs and household odors from cooking, pets and smoke.
Choose this set when a genuine Winix replacement matters and you want both filter types together. For a broader overview of what the different filter layers do, see our guide to electrostatic filters and how they work.
isinlive 115115 Replacement Filter A Size: Best for broad model compatibility
- Compatible with C535 and several other Winix models
- 4-pack HEPA filters
- Brand recommends replacement every 10–12 months
This 115115 option is compatible with the C535 and a broad range of other Winix models. The pack contains 4 HEPA filters, so check whether you also need separate carbon pre-filters.
Pros
- C535 compatibility is stated
- 4 HEPA filters per pack
- Replacement guidance accounts for use and environment
Cons
- Carbon filters are not included in the stated pack contents
The isinlive 115115 set offers 4 HEPA filters for the C535 and other Winix models. Its compatibility list is broad, so compare the model number on your purifier with the set's named models before ordering.
The brand recommends replacing each HEPA filter every 10–12 months, depending on use and environment. Carbon pre-filters are not included in the stated pack contents, so account for those separately if you want to replace both filter layers.
This is a useful format for owners who want several main filters ready for future changes. The set's 115115 Filter A size is the key detail to match with the C535.
XY100T 115115 HEPA Replacement Filter: Best for a three-set bundle
- Compatible with C535 and other Winix models
- 3 HEPA filters and 3 carbon pre-filters
- Brand recommends HEPA replacement every 6–8 months
The XY100T set combines 3 HEPA filters with 3 activated carbon pre-filters for C535 owners. Its replacement guidance separates the main filter from the pre-filter.
Pros
- C535 compatibility is stated
- HEPA and carbon pre-filters are included
- Replacement guidance covers both filter types
Cons
- Brand's recommended intervals may mean more frequent changes
XY100T includes 3 HEPA filters and 3 activated carbon pre-filters for the C535 and other named Winix models. It is one of the sets here that bundles both filter types in multiple quantities.
The brand recommends changing the HEPA filter every 6–8 months and the pre-filter every 2–3 months, depending on use and environment. Those intervals are shorter than Winix's guidance for its genuine set, so review the instructions and your purifier's filter indicator.
The brand describes its HEPA material as HEPA 13 and says it captures particles as small as 0.03 microns. Treat that as the brand's stated filtration claim, rather than a guarantee of results in your room.
Colorfullife C545 HEPA Replacement Filter S: Best for C545 owners
- Compatible with Winix C545 only
- 4 Filter S HEPA filters
- Brand suggests replacement every 6–12 months
This set is made for the Winix C545 and its Filter S format. It does not fit the C535, so choose a 115115 filter instead if you own that model.
Pros
- C545 compatibility is stated
- 4 filters per pack
- Brand gives a use-dependent replacement range
Cons
- Not compatible with the C535
Colorfullife's Filter S set is for the Winix C545 only. It includes 4 C545 HEPA filters and is not a C535 replacement.
Colorfullife suggests replacing these filters every 6–12 months, depending on use. The set names part numbers 1712-0096-00 and 2522-0058-00, which can help C545 owners match their existing filter.
If you own a C545, compare its Filter S options in our Winix 2522-0058-00 replacement filter guide. For C535 owners, choose a 115115 Filter A set instead.
Cabiclean 2 Pack C545 Replacement Filter S: Best for C545 owners needing carbon filters
- Compatible with Winix C545 only
- 2 main filters and 8 activated carbon filters
- Brand recommends main filter replacement every 6–8 months
The Cabiclean bundle pairs 2 main C545 filters with 8 activated carbon filters. It is explicitly not compatible with the C535 or Winix 5500-2.
Pros
- C545 compatibility is stated
- Includes main filters and carbon filters
- Replacement guidance covers both filter types
Cons
- Not compatible with the C535 or 5500-2
Cabiclean's C545 bundle contains 2 main filters and 8 activated carbon filters. The brand says it fits the C545 and explicitly excludes the C535 and 5500-2.
The brand recommends replacing the main filter every 6–8 months and the activated carbon filters every 3 months. If you own a C545, this set supplies both types; if you own a C535, the model mismatch rules it out.
Check the model printed on your purifier before buying. Filter S and 115115 Filter A sets serve different models, even when both are described as Winix replacement filters.
APPLIANCEMATES C535 Replacement Filter for Winix Air: Best for a C535-labelled replacement

APPLIANCEMATES names the C535 among the compatible models for its 115115 Filter A Size 21 set. The pack includes 2 main filters and 8 activated carbon filters.
Its stated filter dimensions are 16.3 x 12.5 x 1.18 in. Compare those measurements with your current filter and verify the model before ordering, especially if your purifier is not a C535.

Fanulter 10 Pack 115115 Filter: Best for extra carbon pre-filters
- Compatible with C535 and other Winix models
- Set contents are 2 HEPA filters and 8 carbon pre-filters
- Brand recommends filter replacement every 6–8 months
The Fanulter bundle includes 2 115115 HEPA filters and 8 carbon pre-filters, and names the C535 as compatible. Its suggested 6–8 month interval is a general recommendation, so consider your use and environment.
Pros
- C535 compatibility is stated
- Includes 8 carbon pre-filters
- Brand gives a replacement interval
Cons
- Fewer HEPA filters than some multi-filter packs
Fanulter's 115115 set includes 2 HEPA filters and 8 carbon pre-filters and names the C535 as compatible. Its larger count of carbon pre-filters may suit owners who expect to change that layer more often.
The brand recommends replacing the filters every 6–8 months, depending on use and environment. It also describes the HEPA filters as capturing 99.97% of airborne particles as small as 0.1 microns.
This pack has fewer HEPA filters than the 3-filter XY100T set and the 4-filter isinlive set. Compare the included quantities with how often you plan to replace each layer.
How to choose a Winix C535 filter replacement
Choose a 115115 Filter A set that names the C535 as compatible, then compare whether it includes both the HEPA filter and carbon pre-filters. A filter made for the C545 uses Filter S and is not interchangeable with the C535 format.
How can you verify Winix C535 filter compatibility?
Check the model label on your purifier and match it to the compatibility list for the replacement set. The 115115 options in this roundup name the C535, while the C545 Filter S sets are for the C545 only.
Do not rely on a broad “Winix replacement” label by itself. Winix models use different filter formats, and the Cabiclean set specifically states that it does not fit the C535.
Should you choose a genuine or compatible Winix C535 filter?
Choose the genuine Winix set if you prefer the manufacturer's own 115115 replacement and its stated schedule. Compatible options can offer multiple HEPA filters or different combinations of main filters and carbon pre-filters.
Compare the pack contents before deciding. A pack with several HEPA filters may not include the carbon layer, while another may include more carbon pre-filters than main filters.
What do the HEPA and carbon filters do?
The HEPA filter is the main particle-filtering layer, while the carbon pre-filter is intended to reduce odors. Winix describes its True HEPA filter as capturing airborne allergens and its carbon filter as reducing VOCs and household odors.
These claims describe the intended filter roles, but they don't tell you how a particular filter will perform in every room. Keep the purifier's instructions and filter indicator in mind when planning replacements.
How often should you replace C535 filters?
Replacement intervals differ by brand and filter type. Winix recommends its True HEPA filter every 12 months and carbon filter every 3 months, while compatible brands here give HEPA intervals from 6–12 months.
Use the instructions for your chosen set and consider your usage and environment. If the purifier's check filter indicator is on, inspect the filter and follow the manufacturer's guidance.
Which Winix C535 replacement filter should you choose?
Choose the Genuine Winix 115115 Replacement Filter if you want Winix's own C535-compatible set with both HEPA and carbon filters. Pick isinlive if you want 4 HEPA filters, or compare XY100T, APPLIANCEMATES and Fanulter when you want bundled carbon pre-filters.
C545 owners should choose a Filter S set such as Colorfullife or Cabiclean, not a C535 115115 replacement. Match the purifier model and filter type first, then compare pack contents and replacement intervals.
