Blueair Blue Pure 211i Max vs IQAir HealthPro Plus XE

Blueair Blue Pure 211i Max for almost everyone: certified 435 CFM airflow, PM1, PM2.5 and PM10 sensing, smart assistant support, low power draw and a far lower price. IQAir HealthPro Plus XE is the specialist pick, justified mainly by its HyperHEPA filtration claim and its 10 year warranty.

IQAir rates the HyperHEPA filtration in the HealthPro Plus XE to capture particles down to 0.003 microns, where the HEPA standard is defined at 0.3 microns, so it targets ultrafine particles a normal HEPA filter is not tested against. It matters for medical or high-pollution scenarios; for pollen, dust and pet dander the difference is largely academic.

Blueair Blue Pure 211i Max is AHAM Verifide at 435 CFM smoke CADR and 674 sq ft. IQAir HealthPro Plus XE publishes no CADR figure and is not AHAM Verifide, so its 1125 sq ft rating comes from IQAir's own testing and cannot be compared like for like.

IQAir HealthPro Plus XE carries a 10 year warranty, by far the longest here, but it draws 135 W and its pre-filter is not washable, so it is replaced with the cartridge. Blueair Blue Pure 211i Max has only a 1 year warranty, yet it is Energy Star certified at 46 W and its washable fabric pre-filter extends a 9 month main filter.

Blueair Blue Pure 211i Max, which connects over Wi-Fi and works with Amazon Alexa and Google Home through the Blueair app, with scheduling and history. IQAir HealthPro Plus XE is monitored through its own app and has no documented Alexa, Google Home, HomeKit, SmartThings or Matter support.

Buyers treating air quality as a medical requirement, or homes facing sustained wildfire smoke or industrial pollution, who want filtration rated well beyond the HEPA standard and a decade of warranty behind a 35 lb Swiss-built machine. Everyone else gets more cleaning per dollar from Blueair Blue Pure 211i Max.
