About this app

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 includes features such as:

Announcing Dark Mode for Alen Air

Introducing Dark Mode, a new feature designed to enhance your user experience. This mode offers a visually pleasing, low-light interface that is ideal for nighttime use or for those who prefer a darker aesthetic.

Key benefits include:

· Improved accessibility
· Reduced eye strain in low-light environments
· Enhanced battery efficiency for OLED displays
· A modern and refined design

Dark Mode defaults to your device’s display setting but can be easily changed in the app settings. We invite you to explore this new feature and enjoy a more comfortable and elegant experience with Alen Air.

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

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 receiving notifications when your filter is close to needing replacement and 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.

Own a lot of Alen units at one or multiple locations? Quickly identify where to focus attention with the highest priority information via the dashboard and organize/manage thousands of purifiers across multiple locations.

Since the Oct. 22, 2024 update, my i75 has erased my set schedules, and app now freezes when I try to set new schedule. Also the purifier is not detecting change in air quality when I cook. Its always been very good at adjusting fan speed to purify air. Now it stays on low fan speed and "Blue" quality indicator. PLEASE FIX WHATEVER YOU BROKE with the recent update. I've had the i75 for 5 months, loving it. Hope that doesn't change.

Hi Randy, We just released version 3.3.0 of the app and that should resolve your issue. Please make sure to update your app and, if you continue to see an issue, please contact our CX team and we'll work to resolve it.

Love the remote features, easy set up, and time series air quality graphing. The big downside is that the AQI is based on 4 hour intervals. This is just too long. If my air is bad, I want real time insights. In future versions, can you incorporate up to the minute insights to illustrate how actions impact AQI? Also, knowing the actual TVOC reading would be nice. The unit itself runs quiet and makes a noticeable difference in air quality.

Where do I start? (1) It only works on 2.4GHz Wi-Fi network. Why? (2) It doesn't save my network's password, forcing me to input the long alphanumeric each time. (3) It never gets pass screen 4 or 5. (4) And if you have to close the app because it freezes, you must start all over again. Frustrating. Time-consuming. Uninstalled.
