Verdict: The Dyson Purifier Cool Formaldehyde TP09 wins on performance and features, thanks to its HEPA H13 filter and unique formaldehyde‑destroying catalytic system. Blueair’s Blue Pure 211i Max offers a more affordable entry point and solid particle capture, but lacks formaldehyde removal and has fewer speed settings. For users prioritizing comprehensive indoor‑air chemistry control, Dyson is the clear leader, while budget‑focused shoppers may prefer Blueair.
