The Alen 45i is priced at $464.0. This cost reflects its ability to purify large rooms up to 1900 sq ft hourly, its advanced HEPA filtration for dust, VOCs, and smoke, and smart sensor technology that auto-adjusts fan speed for optimal performance.
The Alen 45i is ready to use with its built-in smart sensor for automatic fan speed adjustment. It uses a HEPA Fresh Filter + Carbon which will require periodic replacement to maintain peak performance, a common requirement for air purifiers.
The Alen 45i is highly effective, purifying rooms up to 1900 sq ft hourly. It features a CADR (Clean Air Delivery Rate) for smoke of 1216 and a HEPA filter capturing particles as small as 0.1 micron, ensuring rapid removal of airborne contaminants including dust and smoke.
