Alen BreatheSmart Air Purifiers

alen air purifiers

Alen BreatheSmart’s headquarters are run from Austin Texas, in the U.S. They’re focused on creating products that make it easy to keep the air in your home clean. That’s why their air purifiers have been implemented with technology, such as the Auto Mode, that’s simple to use. 

Models & Air Cleaning Features

Depending on the model you choose and speed settings, Alen BreatheSmart’s air purifiers can clean the air in rooms that are 200 – 1,300 square feet. 

Their air purifiers include either regular or true HEPA filters to remove pollutant particles. This works with a carbon activated filter that expels odors, such as gases and cooking smells. 

An Auto Mode is available with some models that detects pollutants and selects the cleaning power automatically. Their control panels also have child-lock features, making them ideal for families with younger kids.

Customer Support

Alen BreatheSmart has phone lines that operate from 8AM-6PM on weekdays and 10AM-4PM on Saturdays. The lines are closed on Sundays but you can contact them via live chat or send them an email. 


Dear AirHonest,

How long do Alen BreatheSmart filters last for?

The HEPA filters in the 75i model require changing every 12-15 months. The 45i, Flex, and T500 model HEPA filters should be changed every 6-9 months.

It’s recommended to replace the HEPA filter in the FIT50 every 10-12 months.

Are there different purifying speeds available?

The 75i, FIT50, Flex, and T500 air purifiers have 3-speed settings. The 45i model only has a one-speed setting.
