## What is Alen Air?

Take control of your environment and make the invisible, visible! The Alen Air app gives you the power to see, control, and analyze your air quality, all in one place, wherever you are. Have you ever wanted to "know it's working"? Now you can! 

Wirelessly control your entire environment, connect to multiple Alen purifiers or Alen Air Quality Monitors right from your phone!

Harness the power of Alen's advanced sensor technology, vivid color rings, and proactive notifications. This app update includes features such as:

Easily add your Alen BreatheSmart 25i, 35i, 45i, 75i purifiers, and Alen Air Quality Monitor (AQM) into the Alen Air app via Wi-Fi or Bluetooth.

The new first-time user experience is designed to get customers up and running in minutes, with a guided, low-friction setup that focuses only on what’s essential. Account creation is simple and clearly explained, requiring minimal information and setting expectations upfront about how data is used. Biometric authentication via Face ID or Touch ID, or authentication using your passcode, provides an optional additional layer of security! 

Once signed in, users can quickly connect their purifier, view air quality at a glance, and control core features without digging through settings. Privacy controls are introduced early and transparently, easy choices that put users in control from the start making clean air immediately accessible.

Creating a new location has never been easier. Simply provide your city or zip code and Alen Air automatically selects the closest outdoor air quality monitor to your locality giving you a good idea about outdoor air quality so you can compare it against your indoor air quality. 

Easily pair your Alen purifier or AQM with the new device onboarding process. Your Wi-Fi network can be automatically detected or, for enhanced security, manually enter your Wi-Fi name and password. Pairing happens through a Bluetooth connection for a fast, no hassle experience making it easy to control your Utopiar.

Alen’s filters have a fresh new look: Pure is now Essential, Fresh is now Advanced, and Odor is now Ultimate. It’s the same filtration you know, now with names that make it easier to choose the right filter for your needs.

Set custom schedules that make sense for your personal life or business, on a single or multiple purifiers. Organizations with many purifiers can achieve efficiencies by setting multiple schedules to reduce day-to-day manual operations.

View your indoor and outdoor air quality, both current and historical, with easy-to-read graphs. Download historical data for custom analysis!

Receive Notifications if your Air Quality reaches a level requiring your attention, like prolonged periods of poor air quality.

Keep your purifiers operating at optimum levels by enabling automatic firmware updates and receiving notifications for when your filter is close to needing replacement, as well as ordering the correct filters by leveraging the app's ability to recognize your purifier model.

Remotely control a single purifier or take the same actions across many purifiers at the same time.

Purchase the full range of Alen products through the Alen Air app’s simple and secure checkout flow.  Buy individual filters and setup filter subscriptions, as well as buy Alen purifiers, air quality monitors, designer panels, and more.

### 1/5 — Does not even recognize my devices

*2026-08-13, version 3.8.0*

I have two units and neither one can connect to the app. Customer service can’t help either - none of the troubleshooting steps worked. It’s hard to justify keeping these expensive purifiers where a basic functionality like this is not working.

### 1/5 — Great Air Purifier, Terrible App

*2026-07-29, version 3.8.0*

The Alen app doesn’t work. I downloaded the app 3 days ago and it constantly drops and disconnects from my iPhone and iPad. I can’t even get it to pair anymore. Not a deal breaker though. I love the machine.

### 4/5 — Finally got app to work!

*2026-07-21, version 3.8.0*

After a few tries to connect to WiFi, I was able to pair my unit. The only negative is the app will show a different color of the sensor than the unit.

### 1/5 — Constant logouts and dropped devices make this frustrating

*2026-07-21, version 3.8.0*

I keep getting logged out randomly, which forces me to sign back in every few days just to control my purifier. On top of that, my devices constantly disconnect from the app — the purifier just drops off and I have to re-add it over and over. When I finally do stay logged in, scheduling is a nightmare. The interface for turning the purifier on or off at specific times is confusing and cumbersome. It should be straightforward, but instead it feels like I need a manual to figure out how to set a simple timer. Fix the stability issues and redesign the scheduling UI — this app shouldn’t be this difficult to use.

### 1/5 — App update crashes on start

*2026-06-28, version 3.7.1*

Edit: Just tried the latest update. Still crashes on open. 

I was prompted to update the app this morning. I checked out the dev notes and clicked update. I no longer have a working app. It vanishes on start up. No error. No warning. I see the app start. The logo appears. And woosh! It's gone. No more convenience for me. No more managing my device from mobile. Another unnecessary digital disappointment disguised as an update.

### 5/5 — app works

*2026-06-23, version 3.7.1*

app works well, it’s nice to see the air quality info for each device. it was easy to setup

### 1/5 — App no longer works

*2026-06-17, version 3.7.1*

Updated the app and now as soon as i login it tells me I have been logged out for security purposes. When the app works it’s great but now it’s useless.

### 2/5 — Meh App- tries hard but doesn’t make it

*2026-05-09, version 3.7.0*

Scheduling function would be great if it worked. Filter reminder also doesn’t work. Always shows great filter life even after a year. Pulled the filter and it was caked with dust and dirt.

“Create a ticket” function in the app doesn’t work. Customer service is non existent. 

I’d buy more of these machines if the app worked and they supported the product.

### 3/5 — Ok when it works properly

*2026-04-29, version 3.7.0*

They recently fixed a bug preventing history from working so that’s a positive. However scheduling is still hit or miss if it’s going to work or not. Sometimes it changes settings like it’s supposed to, but the next schedule to put it back to “normal” doesn’t work. Sometimes it doesn’t change the settings at all. Without this function working it kind of makes scheduling pointless.

### 5/5 — Best air purifiers!!

*2026-04-16, version 3.7.0*

I have a few other air purifiers, which are good, but one of the most popular other models is much louder — plus it app it’s terrible certainly comparison to this one. The pink noise thing here is real. The units are very easy to onboard and they work extremely well. The app is utterly fantastic. I don’t know why it has such a low rating. It’s very well designed easy to get around and it’s just getting better. If you’re looking for an air purifier look no further. I evaluated a dozen of the top ones and again I have several other brands but this one is by far the best!!
