Replacement Filter Size O Compatible with Winix A230 A231 - 2-Pack

Our review of the Replacement Filter Size O is aimed at owners of Winix PlasmaWave A230 and A231 air purifiers who want a simple, cost-effective way to keep their units running at peak performance. The bottom line: this 2-pack of JORAIR-compatible 3-in-1 HEPA filters replaces the OEM filter O (part number 1712-0110-00) and delivers the filtration most households need for dust, pet hair and common indoor particles without fuss. It is a straightforward swap-in replacement that focuses on value and longevity rather than extra bells and whistles.

Key Features

• Compatibility: Designed specifically for Winix PlasmaWave A230 and A231 models, so buyers can expect a snug fit and proper sealing with those units.
• 3-stage filtration: The all-in-one canister combines a pre-filter, HEPA layer and activated carbon for particle capture and odor reduction in one replaceable unit.
• High capture efficiency: The HEPA component is rated to capture up to 99.97% of particles as small as 0.3 microns, which helps reduce dust and pet dander in living spaces.
• Value pack: Two filters in the bundle offer a cost-effective route to year-round maintenance and can lower running costs compared with single purchases.
• Easy to replace: The canister is disposable and installs without tools, making scheduled annual changes quick and simple.
• Responsible material: The filter media uses FSC-certified paper in its construction, a small plus for eco-conscious buyers.

Who It's For

The Replacement Filter Size O is best for households that already own a Winix A230 or A231 and want an affordable, reliable replacement that restores factory filtration performance. It is well suited to homes with pets or light to moderate dust where capturing 0.3 micron particles matters for allergy management and general air quality.

Those who need advanced air cleaning for severe allergies, chemical sensitivities, or very large spaces should consider higher-capacity or specialized filtration systems; this replacement is a like-for-like canister intended to maintain standard purifier performance rather than upgrade it.
