I think you’ll agree with me when I say:

It’s REALLY hard to choose an air purifier with all the options available!

Or is it?

Well, it turns out, that after years and hundreds of hours of testing & reviewing, we have strong opinions about what makes the best air filtration system: level of purification, efficiency, and maintenance.

The Alen BreatheSmart Fit50 (On special until end Jul, 2020) has all the qualities and features, giving it an added advantage and an edge over its competitors.

Quick Summary of the Alen BreatheSmart Fit50

BreatheSmart Fit50 air purifier is like the little engine that could! The team of engineers created an air cleaner purifier inside a compact frame, but made to tackle large rooms. Named the Fit50 because like a bodybuilder, we have trimmed all the fat and are left with an air cleaning machine that works for all your needs. An air purifier for smokers, for wildfire smoke, for strong odor concerns in addition to dust, dirt and mold. The Fit50 is a mighty air purifier that can!

The Good & the Bad


  • A decorator's dream! Multiple color options.
  • Best air purifier for allergies. The Fit50 has the biggest air purifier filter compartment of all of Alen's air purifiers.
  • The Fit50 has the same senor technology used in the BreatheSmart Classic, this is the best air purifier for pets.


  • It has helped very much with the air/allergy issues but not so much with the cat smell.

  • HEPA Odorcell

Common Questions

  • Why do the filters cost more for this smaller model?

The BreatheSmart FIT50 has a thicker filter than the BreatheSmart, which means longer life expectancy, and ultimately a higher price point.

  • Why do all the lights flash at same time, and unit not working?

I recommend calling the Customer Relations team and describe further what you experienced with the home air purifier so they can assess the problem and further assist you.

Our Verdict

The unit is an amazing air purifier, Alen’s True HEPA Pure filter is best for removing airborne allergens, dust, orders, pet smells, cooking odors and smoke. It comes with a high capacity True HEPA layer to capture 99. 97% of airborne particles down to 0. 3 microns and also is a quiet air purifier.
