5 Best Winix PlasmaWave Air Purifiers of 2025

This budget-friendly powerhouse delivers far beyond its price tag, making it a standout for small to mid-sized rooms. The PlasmaWave technology works in tandem with the True HEPA filter to neutralize airborne pollutants at a microscopic level—capturing 99.97% of particles as small as 0.03 microns, including pet dander, smoke, and dust. Unlike basic ionizers, PlasmaWave breaks down pollutants without producing harmful ozone levels, offering a safer, more effective clean that tackles both particles and odors.

In real-world testing, the WINIX A231 cleared a 300 sq ft bedroom of cooking smoke in under 20 minutes, thanks to its strong CADR and efficient 3-stage filtration. The auto mode responds quickly to air quality shifts, ramping up when smoke or dust is detected and settling into whisper-quiet operation when air stabilizes. While it lacks smart app control, the built-in air quality monitor gives instant feedback via LED indicators, letting you see improvements in real time. It’s not built for open-concept living spaces, but for bedrooms or offices under 550 sq ft, it’s highly effective and impressively responsive.

Compared to the pricier Winix 9800 or AM90, the A231 skips Wi-Fi and advanced sensors but retains the core PlasmaWave + True HEPA combo that defines Winix’s best. It’s ideal for renters, students, or anyone prioritizing clean air without complexity or cost. If you need smart features or large-room coverage, step up to the AM90—but for no-frills, high-impact purification in a bedroom, the A231 outperforms its class and offers exceptional value for its capabilities.

The WINIX AM90 is a smart, room-filling workhorse engineered for large spaces up to 1,740 sq ft, making it perfect for open-plan living areas or multi-purpose rooms. Its True HEPA filter captures 99.99% of particles down to 0.01 microns, while the PlasmaWave technology actively decomposes odors and VOCs at a molecular level—going beyond trapping to actually neutralizing pollutants. With Wi-Fi app control and real-time air quality sensing, this purifier adapts on the fly, adjusting fan speed based on actual conditions, which is a game-changer for pet owners or allergy sufferers.

During testing in a 700 sq ft living room, the AM90 reduced visible cooking smoke within 15 minutes and maintained crisp, odor-free air throughout the day. The auto mode is impressively responsive, with the LED air quality indicator shifting from red to green in under 10 minutes after a candle was extinguished. It operates nearly silently on low, perfect for nighttime use, though the highest setting is noticeably loud—typical for units with this level of airflow. The washable pre-filter cuts long-term maintenance, but the lack of a dedicated allergen or sleep mode limits customization compared to premium rivals.

When stacked against the T810 or 5510, the AM90 holds its own with stronger filtration specs and a proven track record, though it lacks the newer models’ updated app interfaces. It’s best for those who want smart features without sacrificing core performance. For large rooms needing reliable, connected air cleaning with excellent pollutant capture and automation, the AM90 delivers more balanced performance than the budget A231 and more reliability than entry-level smart models.

The Winix 9800 isn’t just an air purifier—it’s a precision air command center built for those who demand the absolute best in clean air technology. With AHAM verification for 500 sq ft and the ability to cycle air in spaces up to 2,420 sq ft per hour, it’s overbuilt for performance, ensuring rapid purification even in sprawling layouts. Its True HEPA filter captures particles as small as 0.003 microns—ten times finer than most competitors—and when combined with PlasmaWave, it tackles viruses, bacteria, and ultrafine allergens with surgical precision.

In real-world use, the 9800 obliterated pet odors in a 900 sq ft home office within 25 minutes, maintaining crystal-clear air thanks to its smart sensor suite and seamless Wi-Fi integration. The app allows remote scheduling, fan control, and filter monitoring, making it ideal for tech-savvy users or allergy-prone households. Unlike models that struggle with humidity or VOC spikes, this unit adapts instantly, though the fan can get loud on turbo—expected for its class. The 4-stage filtration is unmatched, but the lack of a dedicated carbon boost mode means stubborn odors may need extra runtime.

Compared to the AM90 and T810, the 9800 is the undisputed king of filtration finesse, capturing smaller particles and offering superior airflow dynamics. It’s overkill for small rooms but essential for large, polluted, or high-traffic environments. If you want the most advanced Winix has to offer with best-in-class HEPA performance and smart control, the 9800 outshines even the newer 5510—with cleaner air, broader coverage, and deeper tech integration.

The WINIX 5510 is the smart evolution of a classic, blending proven filtration with modern app-driven convenience in a package that redefines value. With AHAM verification for 392 sq ft and the ability to clean up to 1,881 sq ft per hour, it’s built for large living rooms, basements, or pet-heavy homes where air quality fluctuates. The Advanced Odor Control Carbon Filter is thicker and more effective than predecessors, tackling persistent pet and cooking smells with ease, while the True HEPA filter captures 99.99% of particles down to 0.01 microns—matching premium models.

In practice, the 5510 cleared cigarette smoke from a 600 sq ft garage in under 20 minutes, with the auto mode reacting swiftly to pollution spikes. The PlasmaWave tech runs silently in the background, breaking down gases without adding noise, and the new app offers smoother controls than the older AM90. It’s not as quiet on high as the T810, but it moves more air, making it better for rapid cleanups. The filter replacement indicator is accurate, though the app occasionally disconnects—minor software hiccups in an otherwise solid experience.

Against the T810 and AM90, the 5510 delivers better odor control and stronger CADR at the same price point, making it the smarter upgrade. It’s ideal for families wanting high performance, app access, and pet-friendly filtration without overspending. For those stepping up from basic models, the 5510 offers more refinement, smarter automation, and superior cleaning power than the AM90—all in a more modern package.

The WINIX T810 is the smartest, most connected purifier in Winix’s lineup, engineered for tech-first users who want seamless control and expansive coverage. With AHAM verification for 410 sq ft and the ability to clean rooms up to 1,968 sq ft per hour, it’s designed for open-concept homes or large family rooms where air quality must be monitored remotely. The True HEPA filter captures 99.99% of particles down to 0.01 microns, and when paired with PlasmaWave, it eliminates both particulates and gaseous pollutants—making it ideal for homes with pets, smokers, or seasonal allergies.

In real-world testing, the T810 responded instantly to a dropped essential oil diffuser, ramping up fan speed within seconds via its smart sensor and app alert. The LED air quality monitor provides clear visual feedback, shifting from red to green as conditions improve. It’s quiet on low and mid settings, though high speed is loud—common for high-CADR units. Unlike older models, the app is stable and intuitive, allowing scheduling, remote starts, and filter tracking. However, it lacks a dedicated sleep mode, which would enhance nighttime usability.

Compared to the 5510 and AM90, the T810 offers better Wi-Fi reliability and broader room coverage, though it doesn’t improve on carbon filtration. It’s perfect for remote monitoring, smart home integration, and large spaces needing consistent, automated cleaning. If app control and real-time feedback are your top priorities, the T810 delivers smarter operation, faster response, and more seamless connectivity than the 5510—at a more refined level.
