Genuine Winix 1712-0110-00 Replacement Filter O: Best for a genuine replacement set

9.7/10Our score

• Compatible with Winix A230 and A231
• Fine mesh pre-filter, True HEPA and activated carbon
• Winix recommends replacement every 12 months

A genuine Winix set with three filtration layers and a stated 12-month replacement interval. It suits A231 owners who prefer the original brand.

See it on Amazon

Pros

• Genuine Winix filter set
• Three filter layers
• Stated 12-month replacement interval

Cons

• One filter set per pack

Winix's 1712-0110-00 set is the straightforward option for an A231 owner who wants a genuine replacement. It is also compatible with the A230, and its three named layers are a fine mesh pre-filter, True HEPA filter and activated carbon filter.

Winix says the True HEPA filter captures 99.97% of airborne allergens as small as 0.3 microns. The activated carbon filter is designed to reduce VOCs and household odors from cooking, pets and smoke.

Winix recommends changing the all-in-one canister filter once every 12 months. That gives you a clear starting point for planning, though your purifier's instructions should guide your replacement schedule.

Choose this set if original-brand compatibility and a defined interval matter most. If you want more than one replacement at a time, compare it with the compatible two-packs below.

2

JORAIR Replacement Filter Size O: Best for a two-pack with 3-stage filtration

9.4/10Our score

• Compatible with A230 and A231
• Pre-filter, high-efficiency filter and activated carbon
• 2-pack

This two-pack combines a pre-filter, high-efficiency filter and activated carbon. JORAIR recommends changing the all-in-one filter once every 12 months.

See it on Amazon

Pros

• Two filters in the pack
• Three filtration stages
• Compatible with A230 and A231

Cons

• Compatible replacement, not a genuine Winix set

JORAIR's Size O option is a two-pack compatible with Winix A230 and A231 purifiers. Each filter is described with a pre-filter, high-efficiency filter and activated carbon stage.

JORAIR says its filter captures up to 99.97% of airborne particles as small as 0.3 microns. The brand recommends changing the all-in-one filter once every 12 months, matching the stated interval for the genuine Winix set.

This pick suits buyers who want a spare compatible filter ready for the next change. Compare the part number printed on your existing filter with the description before ordering, since model and part number labels can vary.

Choose JORAIR if a two-pack and three-stage construction fit your needs. If you prefer a shorter replacement interval based on use, Lichelete gives different guidance.

3

Lichelete A230 Replacement Filter for Winix A230: Best for a two-pack with shorter change guidance

9.3/10Our score

• Compatible with A230 and A231
• Pre-filter, high-efficiency filter and activated carbon
• 2-pack

Lichelete provides two compatible filters with three filtration layers. Its replacement guidance is every 3–6 months or based on use.

See it on Amazon

Pros

• Two filters in the pack
• Three filtration stages
• Replacement interval guidance included

Cons

• Change interval is shorter than some other picks

Lichelete's A230 replacement is a two-pack that names compatibility with both A230 and A231. Its three filtration layers are a pre-filter, high-efficiency filter and activated carbon filter.

Lichelete says the filter captures up to 99.97% of airborne particles as small as 0.3 microns. The brand recommends replacing it every 3–6 months or based on use, which is more frequent guidance than the yearly interval given for the genuine Winix filter and JORAIR.

That shorter interval can matter when planning how many filters to keep on hand. The package also carries a one-year manufacturer warranty.

Choose this set if you want two compatible filters and prefer a shorter stated change schedule. For a two-pack described with an H13 filter and fine mesh pre-filter, consider Netezza.

Netezza 2 Pack A230 A231 Replacement Filters: Best for a two-pack with a pre-filter

9.2/10Our score

• Compatible with A230 and A231
• Fine mesh pre-filter, H13 filter and activated carbon
• 2-pack

Netezza's two-pack includes a fine mesh pre-filter, H13 filter and activated carbon. The brand describes each filter as designed to last up to 12 months.

See it on Amazon

Pros

• Two filters in the pack
• Three filtration stages
• Fine mesh pre-filter

Cons

• Compatible replacement, not a genuine Winix set

Netezza's two-pack names both A230 and A231 compatibility. It describes a fine mesh pre-filter, H13 filter and activated carbon filter, making the filter layers clear for shoppers comparing replacement sets.

Netezza says each filter is designed to last up to 12 months. Its filtration claim differs from the other picks: the brand describes capture of up to 99% of dust, including pet hair, dust, pet dander and smoke.

Choose Netezza if you want two filters with a fine mesh pre-filter and a stated lifespan of up to a year. As with any compatible option, confirm the purifier model and filter fit before ordering.

5

Nispira True HEPA Replacement Filter Compatible: Best for a three-pack

8.9/10Our score

• Compatible with A230 and A231
• True HEPA and activated carbon pre-filter
• 3-pack

Nispira includes three compatible filter sets with True HEPA and activated carbon filtration. The larger pack may suit buyers planning ahead for future changes.

See it on Amazon

Pros

• Three filters in the pack
• True HEPA and activated carbon
• Compatible with A230 and A231

Cons

• No replacement interval stated

Nispira's option includes three filters compatible with the Winix A230 and A231. It is the largest pack in this roundup, with True HEPA filtration and an activated carbon pre-filter described for odor control and larger particles.

Nispira says its True HEPA filter captures up to 99.97% of particles as small as 0.3 microns. It does not give a replacement interval here, so use the filter and purifier instructions to plan changes.

Choose this pick if you want three compatible filters in one pack and don't need a stated interval to compare. If filter layering matters more, the genuine Winix, JORAIR, Lichelete and Netezza options explicitly describe a separate pre-filter, HEPA layer and carbon stage.

What should you compare before buying an A231 filter?

Check the model fit first, then compare filter layers and pack size. For another brand-specific option, compare Honeywell HPA300 replacement filters.

The A231 picks above also name the A230, but other Winix filters may not fit either model.

The genuine Winix set uses part number 1712-0110-00. Compatible options refer to Size O and may include 1712-0100-00 in their descriptions, so compare that identifier with your current filter and the purifier's model.

Next, decide whether you want a single genuine set or a compatible multi-pack. A larger pack means you can keep another replacement nearby, but it doesn't tell you how long each filter should stay in use.

What do the filter layers do?

A pre-filter is the first layer for larger particles, while the HEPA stage is described for smaller airborne particles. An activated carbon layer is included for odor reduction in several of these options.

The genuine Winix set has a fine mesh pre-filter, True HEPA filter and activated carbon filter. Learn more about what a pre-filter does in an air purifier and what a charcoal filter does.

The terms and claims differ by brand, so compare what each one actually names. Nispira describes an activated carbon pre-filter, while most of the other picks describe carbon as a separate stage.

How often should you change the filter?

Replacement intervals vary by brand and filter. Winix recommends every 12 months for its all-in-one canister, JORAIR also recommends 12 months, and Lichelete recommends every 3–6 months or based on use.

Netezza describes each filter as designed to last up to 12 months, while Nispira gives no interval in the information here. Check your purifier's instructions and the guidance for the filter you buy, and don't treat one brand's interval as universal.

If you are comparing other Winix filter references, our guide to Winix 2522-0058-00 replacement filters covers a separate part number. Always confirm model compatibility before ordering.

Which Winix A231 filter should you choose?

Choose the genuine Winix Filter O if you want the original-brand set and a stated 12-month interval. Pick JORAIR for a compatible two-pack with three filtration stages, Lichelete if its shorter replacement guidance suits your use, Netezza for a fine mesh pre-filter and H13 stage, or Nispira if you want three filters in one pack.

The right Winix A231 air purifier replacement filter is the one that matches your model and your preferred replacement plan. Compare the filter part number and layers before you order.
