How a BreatheSmart 45i Purifier Works

Air is drawn into the unit and filtered at a high rate. The BreatheSmart 45i can purify large amounts of air, up to 800 Sqft in 30 minutes, while maintaining a peaceful, quiet, environment. Once inside, the air moves through advanced True HEPA material where a wide range of allergens and pollutants are captured. Finally, purified air is then circulated back into the room.


When to Use an Alen BreatheSmart 45i

After conducting air quality studies, our Air Purifiers America experts have found the air quality in a room can returned to pre-cleaned levels only two hours after turning off an air purifier. Based on these findings, we recommend you run your air purifier 24/7 to maintain the cleanest air possible. If you run your air purifier at the recommended levels, you air purifier will require a new filter every 9-12 months.
