2026 verdict
The Blueair Blue Pure 211i Max reports three particle sizes and moves far more air, yet the Winix 5510 air purifier still wins on price, warranty length and smart home integrations, backed by a 2-year warranty against just one year of coverage on the Blueair. The Blueair Blue Pure 211i Max remains the stronger choice for a genuinely large, open-plan space: its HEPASilent stage is rated for a considerably higher smoke CADR and a bigger coverage area, and it is the only one of the two to break particle readings into PM1, PM2.5 and PM10 instead of a single number. Filtration otherwise runs close between them, with the Winix 5510's extra edge coming down to a switchable PlasmaWave ionizer stage that the Blueair leaves out entirely. Buyers filling a large, open room who want granular particle data and don't mind paying more for it should choose the Blueair Blue Pure 211i Max; anyone furnishing a normal-sized room who wants the cheaper, longer-warrantied and better-integrated option should choose the Winix 5510.
