Alen BreatheSmart 45i 800 SqFt Air Purifier with Fresh HEPA Filter - Brushed Stainless

I’ve been using the Alen BreatheSmart 45i for about a month now, and I have to say—it’s an absolute game-changer when it comes to air purification. From its sleek and refined design to its impressive performance, this purifier checks all the right boxes for me. Design & Customization One of the standout features of the Alen BreatheSmart 45i is its aesthetic appeal. Unlike bulky, industrial-looking air purifiers, this one is designed to fit seamlessly into any home decor. What I love even more is the interchangeable panel design, allowing you to choose a finish that complements your space. Whether you want a modern or classic look, Alen gives you options. Performance & Efficiency This purifier isn’t just about looks—it delivers powerful air-cleaning performance. It can clean up to 1,600 square feet of air per hour, which is incredible for maintaining a fresh and healthy home environment. Despite its efficiency, it operates quietly, making it perfect for bedrooms, living areas, or even home offices without being disruptive. Smart Features & App Integration Another feature I love is the smart app control. The app is user-friendly and highly efficient, allowing me to control the purifier remotely—a fantastic option when I’m away from home but still want to maintain air quality. Having the ability to adjust settings, monitor air quality, and turn the unit on or off from anywhere adds a whole new level of convenience. Final Thoughts The Alen BreatheSmart 45i is an air purifier that not only performs exceptionally well but also blends beautifully into any home. It’s powerful, whisper-quiet, and smartly designed, making it a fantastic investment for anyone looking to improve their indoor air quality. If you want style, efficiency, and smart features all in one, this is definitely worth considering!

Quiet and very efficient. It was shocking to see how much dust it collected.

Love my Alen purifyiers. The ring helps me to know when they are picking up something in the air and then it clears it and the color changes again. It is comforting. Only disappointment is that mine cannot be upgraded to the new versions that are reading voc’s, since this was the main reason for the 45i. And I have an older 75i that I guess is now outdated unfortunately l

I can't believe how much of a difference this purifier made! We suffer from wildfire smoke for the majority of the summers now and it has been a struggle for our family. With the purifier, we don't have to take our morning allergy pill nor have to wear glasses due to constant irritated eyes. Most importantly, we no longer struggle to breathe and our constant headaches from the smoke are gone. Our sleep quality noticeably improved too. It is an amazing investment and we love it so much that we bought another one for our second floor.

I bought it yesterday but I noticed it doesn’t have UV light my loved one was diagnosed with TB so I rushed to get this but have to return it and find something with UV

so far it is all your company professed it would be and do thank you verden white

Love it. It's very quiet. Gets rid of odors quickly. We breathe easier, and sleep better. We have one in our bedroom and one in the living room.

Unit fits well in smaller bedroom. Like the light dimmer option. Quiet just like my 75i. Working well so far.

Great purifier! We own two 45i and one 75i. The 45i in the bedroom keeps the bedroom fresh and is whisper quiet. This unit kicks in to high gear fast when I flat iron my hair or light a candle. It really makes you aware of things that affect your air quality. I just recommended Alen Air to my stylist for the salon. He has a very modern style so I am glad it comes in black and stainless. Another reviewer mentioned wanting the ability to turn the light off from the app. You can put the unit in sleep mode by touching the colored ring on the remote in the app. It used to be more obvious in the previous software version, but the functionality is there.

This air filtration system is the best for my living room. It keeps odors, dust particles out. Very easy to change the filters and I love having the subscription for the filters. It makes it worry free. When the filter arrives I just change it. I don’t really need to remember to change the filter. I can just change it when it comes and it looks nice in my living room. Well worth the price

Air quality Improved and ease of use for the Alen Air Purifier. It's a quiet machine keep ours on 24 hours a day. It has a sensor to detect change in air quality as well. I use it on a preferred setting all the time. It's simple to maintain, and the replacement filters come in a variety based upon one's individuals needs or concerns. The unit has been running without any issues. The cheaper brand machines just don't compare. I have 2 so far and am considering replaced another brand that just doesn't do the job to my satisfaction. The cost may be a little more but when you see what this removes from your inside air is amazing. We have no smokers in our home as well. So I know I am breathing better and sleeping better as a result.

Air quality in the bedroom is fresher. No more stuffy nose in the morning.

Love love my Alen Purifiers, total of three. My house smells so clean and the dust particles are minimal. Setup was super easy. Researched a lot of purifiers and the Alen BreatheSmart won hands down implementing my decision. The BreatheSmart 45i out performs any previous systems purchased. Extremely pleased customer and your customer support service is always readily available and very knowledgeable with air quality needs. Also love the “White noise” on high for a good nights sleep. Truly my pleasure to give you a 10 plus rating.

Setup was fairly easy for my daughter. It looks nice in my livingroom. And seems to be working well at odors and helping breathing.

Auto mode is great for increasing filtration when needed and reducing when air monitors clean air ! Using WiFi App is great for controlling and monitoring this and other units - App does not currently allow control of panel lights and that would be a great improvement .

Perfect for our bedroom! I appreciate the feature that allows me to dim the controls so I can sleep without light!

Hav had many different brands over the past 30+ years and love this one the best!

My Alen 45i arrived carefully packaged, and it appears well made (a solid, sleek unit). It was easy to set up and is quiet. My sinuses have felt better since getting this. I like that the light indicator changes according to conditions, but I don’t know why it's sometimes green or even blue (best quality air ) when we leave LR (with open area toward kitchen) to go to bed upstairs, and in the morning it’s often purple (worst quality), then it fluctuates throughout day, often toward better quality air (unless I burn something on the stove!). It takes 4-5 weeks to adjust to a space, so we’ll see how things go. Given that we don’t have central air so don’t have an air filter on the furnace, this is doing the work of purifying and feels like a healthy addition.

This is the second Alen that I have . I’ve had the classic filter for over 10 years . Great warranty. I just bought the 45i . The tech just keeps getting better. Love the app . The 45i is very quiet on the 2 lowest speeds. Same as the classic but quiter. Same lifetime warranty. You absolutely can not go wrong. The 2 air purifiers are keeping our house fresh and healthy. My sinuses have improved since adding the 45i in my family room. I highly recommend, great product.
