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 update includes features such as:

Easily add your Alen BreatheSmart 35i, BreatheSmart 45i and 45iV2, BreatheSmart 75i and 75iV2 purifiers, and Alen Air Quality Monitor (AQM) into the Alen Air app via Wi-Fi or Bluetooth.

This version of Alen Air includes full support for our NEW 25i including replacement filter purchase! Our smallest, most affordable BreatheSmart yet, features the same stunning, award-winning Alen design, powerful, yet quite airflow, the same easy to pair Bluetooth and dual-band wi-fi capabilities, and suite of sensors. Perfect for small spaces up to 400 square feet!

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.

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.

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.

I don't use the app very often because it logs me out and every time I log in I have to follow the inconvenient steps to re add my air purifier. I am tired of adding it like it is a new device when I should be able to open my app and see it any time. It should always recognize it as an existing device. It is very annoying. I may have been not using it often because it kept removing my purifier for no reason so I just haven't bothered.

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.

I love my Alen equipment, but the app is clumsy to set up, disconnects easily, and doesn't reconnect easily. And the functionality it offers isn't worth the trouble or time. I'm not sure an app is really necessary anyway, so as long as they're good at producing excellent air purifiers, I'll be happy. Just don't expect a lot. The interface is attractive and I appreciate what it's trying to do, but it's obvious that connectivity isn't a priority on the equipment side or the app development side.
