Alen BreatheSmart Fit50 Air Purifier


The Alen BreatheSmart air purifier is an impressive combination of simple design and smart technology. Its large, plain exterior houses a specially designed fan and air chamber that allows the air purifier to clean a large amount of air while maintaining a peaceful environment. The BreatheSmart's noise level is in the pink noise spectrum, which provides a more relaxing, low-frequency sound than white noise. It is very easy to use with large, intuitive push-button controls, active air quality sensor, filter life timer and a magnetic front panel for easy access to the filters. The Alen BreatheSmart air purifier includes a True HEPA-style filter for dust and allergen removal. It is well suited for large rooms up to 1100 sq. ft. Now available in white and 3 additional fashion colors to match your décor.

The Alen BreatheSmart Air Purifier features an easy to replace True HEPA (High Efficiency Particulate Air) style filter that combines several layers of filter technology to purify and freshen the air in your home. Polluted air first passes through Alen’s washable pre-filter to capture large particles, extending the life of the filter. In the second layer, air moves through a unique, electrostatically charged True HEPA style material that attracts and captures up to 99% of dust, pollen, pet dander, mold spores and other airborne pollutants. Optional filter upgrades are available with additional filtration layers to address bacteria, chemicals, heavy odor and smoke concerns. An optional ozone-safe ionizer complements the True HEPA style filter by charging particles in the air, causing them to stick together and become more easily captured.

We recommend cleaning the pre-filter every 2-3 months and replacing the True HEPA-style filter at least every 10 to 12 months with normal use. The Alen BreatheSmart’s Filter Life Timer indicates when it is time to replace the filter based on the operating fan speed and duration of use. The optimal filter replacement frequency may vary based on your environment and health concerns.

The BreatheSmart is larger and more expensive than Alen's other air purifiers; however, it is quickly becoming their most popular model and exceeding expectations. The Alen BreatheSmart air purifier features WhisperMax technology to offer the greatest coverage while producing the least amount of noise. Furthermore, it offers SmartSensor technology for optimal air cleaning and efficient energy use.


  • Excellent instructions and labeled controls on how to use the air purifier right out of the box.
  • Excellent filtration of particles. Our testing showed a 97% average reduction in particles 0.3 microns and greater on the first air pass.
  • Large room coverage. Even when running on speed 2, this air purifier is able to clean the air in a 700 square feet room achieving 2 air changes per hour.
  • Control buttons are large and labeled for clear, easy operation.
  • Front control panel is magnetic and easy to remove to access the filters for cleaning or replacement.
  • Built-in handle makes it easier to move the air purifier.
  • Use of the ionizer is optional.
  • The smart air quality sensor is color coded to clearly show when air quality is good, moderately polluted or heavily polluted.
  • Indicator lights and air quality sensor light can be turned off for nighttime use.
  • Auto-mode automatically adjusts fan speed up or down depending on the air quality detected. This not only helps keep your air clean, but operates the air purifier at its most efficient level to save you energy.
  • Impressively quiet on speeds 1, 2 and 3. The fan has a quiet, consistent, smooth sound which is not disturbing and is ideal for sleeping.
  • Available in 4 color options to match your décor.
  • The smart filter life timer accurately indicates when to change the filter based on actual operating fan speed and duration of use. It has 3 indicator lights to track the filter's life: Green = good, Yellow = time to order a new filter and Red = time to replace.


  • Much larger in size than Alen's other air purifiers.
  • Turbo setting is loud. If you have poor air quality and are running this air purifier on auto-mode it will be noisy.
  • Standard True HEPA-Pure filter does not offer any gas, odor or chemical filtration. We do offer 3 upgraded BreatheSmart filters which offer additional filtration capabilities. (See Filters & Accessory section to purchase.)
  • Filter may need to be replaced frequently if running 24/7. Estimated filter life is 6-12 months with high use, 10-12 months for normal use and only 12-18 months for light use.


The first thing that stands out about the Alen BreatheSmart air purifier is its size. There is no denying that this air purifier is large; however its size is proportionate to the amount of air it can move, resulting in large room coverage which is a plus. The second thing that stands out about this air purifier is how simple and intuitive it is to use. Alen has thoughtfully designed the BreatheSmart so anyone can use it, featuring large, clearly labeled controls - no tricky little buttons or confusing, overly-engineered controls. Its simplicity is perfectly complimented with smart sensors and indicator lights adding to its ease of use. Lastly, its quiet "pink noise" sound level on speeds 1-3 is quite impressive, especially for its size. Its pleasant sound level and ability to turn off all illuminated controls/indicators makes it a great choice for bedroom use.

We recommend the Alen BreathSmart air purifier with True HEPA-Pure filter for an allergy sufferer looking to remove dust, pollen, pet dander and other irritating airborne particles from an indoor area up to 1100 square feet. Three upgraded replacement filters are available for the Alen BreathSmart air purifier. Choose the True HEPA-FreshPlus for additional chemical, VOC and odor control, choose the True HEPA-Silver filter for antimicrobial protection, or choose the True HEPA-OdorCell with activated carbon for heavy odor filtration.
