Editor's Take
Amazon reviewers say the Winix 9800 is very quiet, effective at improving air quality, and easy to use and clean, with several praising the sensor and overall value. The main complaint is inconsistent Wi‑Fi connectivity, including reports that the app can be finicky and that some users had trouble with Alexa or 2.4G-only setup.
On Reddit, users describe it as a strong performer that works well and is very quiet, with one thread calling it a “workhorse.” Reddit discussions also suggest it is not ideal for odor/VOC-heavy situations, where expectations should be tempered. A review blog and Consumer Reports both frame it as a solid mid-range air purifier, while broader expert coverage highlights good build quality, strong sensor behavior, and quiet operation.
YouTube results include reviews that are directly about the Winix 9800, including videos titled “Winix 9800 Review → The Replacement to the Discontinued 5500-2?” and “Winix 9800 Air Purifier Review: Smart, Quiet, and Efficient!”
