Key item features
- Why choose Alen? We're top rated and we stand by you for life (Alen has the only Forever Guarantee in the business).
- FL40-H Smoke Air Filter: HEPA filter with over 2 lbs of activated carbon, HEPA captures 99.9% of dust, allergens, aerosolized viruses, and other fine particulates down to 0.1 micron while the carbon layer traps Smoke vapors, Volatile Organic Compounds (VOCs) and other harmful gaseous contaminants.
- Room to Breathe: Ideal for most rooms in the house from bedrooms to living rooms or even home offices, clean 800 SqFt every 30 min.
- SmartSensor Technology: Displays air quality status in 5 LED colors, so you never need to wonder if it's working. Designed to run 24/7, constantly monitoring air quality. Using laser-sensor technology to auto-adjust fan speed when airborne particles are detected, our LED color rings let you know when harmful particles get stirred up.
- Quiet and Powerful: Engineered with care for maximum airflow with minimum sound output - one that equates to a gentle rainfall on the highest setting.
- Energy Efficient: 50 Watts on the highest setting, so you can set it and forget it – let BreatheSmart 45i do the cleaning for you.

Good
I purchased the Alen BreatheSmart 45 for our master bedroom and it has been excellent so far. It's powerful enough to handle the space, and within a short time we noticed the air quality feels much better—cleaner, fresher, and overall more comfortable. The unit runs quietly, even on higher settings, and the design blends in nicely with the room. Overall, I'm very happy with this purifier. It does exactly what it promises and has made a noticeable difference in our home's air quality. Highly recommend!

The best!
The best air purifier on the market! My main goal was to get rid of cooking smells, and this filter does the job perfectly. I also tested it at my workplace, where mildew had occurred, so the space could be safely occupied before construction. Thanks to this air purifier, the air was clean - no smell and no symptoms from the mildew. I'll definitely be getting another one for my bedroom and workspace.

Love them!
I bought 2 of these earlier this year. Best purchase ever. I can breathe better now thanks to them. We live on a high-traffic road, so there is a lot of dust and pollen, and this air purifier literally filters most of the particles out automatically, and will indicate the air quality, then adjust on its own accordingly!!
