Product fact sheet
Blueair Blue Pure 211i Max
Current-source Blue Pure 211i Max record covering current DOE-presented CADR, time-based room coverage, HEPASilent electrostatic/mechanical filtration, power, sound and warranty.
A high-CADR room purifier using Blueair's HEPASilent combination of mechanical and electrostatic filtration, with current room-size and CADR figures published under updated U.S. DOE presentation.
See documented specifications and comparison context.
See technical gaps, safety notes and source limitations.
Key tradeoff: Blueair notes that CADR and room-size values have been updated to newer DOE standards, so current web values should not be silently mixed with older packaging or archived figures.
This is a factual fit-and-tradeoff summary, not a product recommendation. Formula, device and brand claims remain manufacturer claims unless the cited source is explicitly regulatory or independent testing.
What the current documentation establishes
Blueair’s current U.S. page lists CADR of 450 CFM pollen, 452 CFM dust and 435 CFM smoke. It describes room cleaning of 674 square feet in 12.5 minutes, 1,618 square feet in 30 minutes, and 3,235 square feet in one hour. Those figures should be kept with their stated time basis rather than collapsed into a generic square-foot claim.
The unit uses Blueair’s HEPASilent system, which combines mechanical particle filtration with electrostatic assistance and carbon media. The page lists 46 W maximum power, 23–53 dB sound, 16.2 lb weight and dimensions of 22.7 × 14.4 × 14.4 inches.
Why older CADR figures should not be mixed in
Blueair says its current U.S. CADR and room-size presentation has been updated for newer Department of Energy standards. Older packaging, archived pages or retailer copy can therefore show different numbers. Homeapotherapy uses the current manufacturer page and keeps the retrieval date visible instead of mixing generations of test presentation.
Ozone and ionization disclosure
The current product page describes HEPASilent as mechanical plus electrostatic filtration. It does not publish a numeric ozone-output value for the 211i Max. Homeapotherapy therefore does not infer a measured zero-ozone result from silence in the specification table.
Warranty
Blueair lists a one-year warranty, extendable to three years after product registration. Current registration and eligibility terms should be checked at purchase.
Evidence boundary
Homeapotherapy has not independently reproduced CADR, room-cleaning time, acoustic output or ozone emissions for this unit. These are manufacturer-published specifications, not clinical-outcome evidence.

What the current record does not establish
- The current product page explains electrostatic filtration but does not publish a numeric ozone-output value; Homeapotherapy has not independently measured ozone.
Source labels preserve provenance. Manufacturer specifications, ingredient lists and performance claims are not treated as independent clinical evidence; regulatory records and independent measurements are identified separately when available.
Safety first
What should make you slow down?
Follow the current manufacturer instructions; Blueair's current page describes mechanical plus electrostatic HEPASilent filtration but does not publish a numeric ozone-output specification for this model.
