Blueair · SPECIFICATION PROFILE
Blue Pure 511i Max
A compact comparison point with an explicitly labeled smoke-CADR figure. The source’s inconsistent maximum-noise claims mean noise deserves direct confirmation.
Direct, untracked manufacturer link. Prices are dated snapshots, not live offers. The Home Briefing has not hands-on tested this product.
What to check before choosing
Noise: technical specifications list 19–48 dB; the FAQ lists 19–42 dB.
Listed room coverage depends on the air-change and ceiling-height assumptions. Minimum noise should not be paired with maximum CADR as though they occur at one fan speed. A purifier does not supply fresh outdoor air.
Replacement-filter price snapshot: Not captured. This is not an annual ownership cost. Confirm the exact model, pack contents, change interval and current price before ordering.
