While its high CADR and HEPASilent filtration can clear a large, pet-heavy room up to 540 sq ft, the Blue Signature Large is ultimately a niche performer. It operates at an exceptionally quiet 23 dB and its washable pre-filter handles hair well, but its overall consensus for dedicated allergy relief is low. For a spacious, dusty apartment where noise is a primary concern, it's a competent machine, but stronger all-around contenders exist.
