Comparing Blueair Purifier Features
Filtration technology
Both units use Blueair's HEPASilent technology to capture airborne particles. The Signature SP1i (Product B) specifies a 7-stage filtration process that captures 99.97% of particles down to 0.1 microns. It also includes OdorFence Technology to break down odors, gases, and volatile organic compounds. The Sunrise Alarm model (Product A) lists standard HEPASilent filtration that removes 99.97% of particles like pollen, dust, and pet dander. While both effectively remove particulates, the Signature SP1i offers a more detailed multi-stage approach with specific odor reduction capabilities for a broader range of indoor pollutants. This makes it slightly more versatile for complex air quality needs.
Room coverage
The intended room size is a major differentiator between these two devices. The Signature SP1i (Product B) is designed for larger spaces, capable of cleaning rooms up to 1,190 square feet every hour and small spaces up to 248 square feet in 12.5 minutes. In contrast, the Sunrise Alarm model (Product A) is built for smaller areas, cleaning a 140 square foot room in 12.5 minutes. If you need to purify a large living area, office, or open-concept space, the Signature SP1i is the necessary choice. For a compact bedroom or dorm room, the smaller model is sufficient and more appropriately sized.
Noise level
Quiet operation is critical for bedroom devices, but the specifications provide different levels of detail. The Signature SP1i (Product B) explicitly states it operates as low as 19 dB, which is whisper-quiet and designed not to disrupt sleep or focus. The Sunrise Alarm model (Product A) describes its technology as quiet but does not provide a specific decibel rating in the published data. While both are intended for bedroom use, the Signature SP1i provides concrete data confirming its ultra-low noise performance, giving you certainty about its suitability for light sleepers.
Special features
These devices serve different primary functions beyond air cleaning. The Sunrise Alarm model (Product A) is an all-in-one bedside device that includes a gradual sunrise alarm clock, adjustable nightlight, and on-device controls for alarms and brightness. It simplifies your bedside table by combining these functions. The Signature SP1i (Product B) focuses solely on air purification, featuring an air quality indicator with a 5-color display and interchangeable pre-filters for style customization. If you want a dedicated air purifier with smart sensors, choose the Signature. If you need an alarm clock and nightlight integrated into the unit, the Sunrise model is the better fit.
Physical dimensions
The physical footprint of each unit affects where you can place it. The Sunrise Alarm model (Product A) is compact, measuring 6.69 inches wide and deep, with a height of 11 inches and a weight of 3.92 pounds. The Signature SP1i (Product B) is larger, measuring 9.37 inches wide and deep, with a height of 13.8 inches and a weight of 5.64 pounds. The smaller model is easier to fit on a crowded nightstand or in a tight corner. The larger Signature model requires more floor or surface space but offers greater air cleaning power for its size.
