Alen 35i vs 45i Spec Breakdown
Room Coverage
The Alen BreatheSmart Large Room Air Purifier covers up to 1,400 square feet. This makes it suitable for large bedrooms, living rooms, or offices. The Alen BreatheSmart HEPA Air Purifier handles a larger area of 1,900 square feet. It circulates air efficiently across that bigger space every hour. If you have a very open floor plan or a large dining room, the 45i model provides broader coverage. The 35i is still effective for its rated size, but the 45i reaches further. You should match the unit to your actual room dimensions for best results.
Physical Dimensions
Size and footprint matter for placement. The Alen BreatheSmart Large Room Air Purifier measures 13 inches wide, 20.6 inches high, and 7.6 inches deep. It weighs 10 pounds. The Alen BreatheSmart HEPA Air Purifier is taller at 25 inches but narrower at 8.5 inches wide. Its depth is 15 inches, and it weighs 14 pounds. The 35i has a wider, shorter profile, which might fit better against a wide wall. The 45i is slimmer and taller, potentially saving floor space but requiring vertical clearance. Consider your available square footage and height restrictions when choosing.
Filtration Grade
Both units use H13 HEPA filters to capture particles as small as 0.1 micron. The Alen BreatheSmart Large Room Air Purifier includes the Essential Filter with this H13 HEPA capability. It eliminates 99.9% of allergens, germs, bacteria, and pollutants. The Alen BreatheSmart HEPA Air Purifier comes with the Ultimate Filter. It also uses medical-grade filtration to capture the same tiny particles. Both models provide strong protection against dust and pollen. The core filtration technology is identical in effectiveness for particulate matter, ensuring clean air in both cases.
Smart Features
Each purifier features SmartSensor technology to adjust fan speeds based on air quality. The Alen BreatheSmart Large Room Air Purifier provides color-coded feedback, with blue indicating excellent air and purple signaling high particles. The Alen BreatheSmart HEPA Air Purifier also uses SmartSensor for automatic adjustment and color-coded monitoring. Both units operate in auto mode to maintain air purity without manual intervention. You do not need to guess when to change settings. The sensors handle the work, ensuring the fan runs only as needed to keep the air clean.
Odor Control
Odor management differs between the two models. The Alen BreatheSmart HEPA Air Purifier includes a HEPA Odor Filter that destroys heavy household odors at the molecular level. It neutralizes smells from food, litter boxes, and diapers, making it ideal for pet owners. The Alen BreatheSmart Large Room Air Purifier description focuses on particle removal and does not mention an odor-specific filter. While it captures allergens, it may not handle strong smells as effectively as the 45i. If odors are a primary concern, the 45i offers a distinct advantage.
