Similarities Between Each Alen BreatheSmart Model

Photo of Alen BreatheSmart Color ChoicesWhen you’re researching and comparing Alen BreatheSmart air purifiers, you’ll quickly discover that all of the models include a common set of features.

This is a nice quality to have because it means you don’t have to sacrifice air cleaning performance even when you choose a lower-priced model.

Alen meets the most important air purifying needs in each machine.

Regardless of the air purifier you choose, you’ll enjoy these benefits:

  • Customizable HEPA Filter (Traps 99.97% of pollutants down to 0.3 microns in size.)
    • HEPA-Pure – This is the basic version of the filter that removes indoor allergen particles, such as dust, pollen, pet dander, and mold spores.
    • HEPA-Silver – This version includes an antimicrobial compound on the HEPA material that protects it from bacteria and microbe growth. An additional layer of Activated Carbon also reduces light odors and chemical compounds in the air.
    • HEPA-OdorCell – This version features hundreds of cells filled with Alen’s patented Molecular Conversion Powder in addition to the HEPA material. Odors from pets, babies, and cooking are destroyed at a molecular level to leave the air smelling fresh.
    • HEPA-FreshPlus – This version includes 3 lbs. of Activated Carbon in addition to the HEPA material. It provides maximum performance against household odors and chemical vapors from cleaning products, smoke, cooking, pets, etc.
  • Smart Sensors – These sensors monitor the air quality and automatically adjust the device’s fan speed to filter out pollutants. Consider it intuitive intelligence that works on your behalf.
  • Numerous Color Options – More than 14 different colors and designs available so you can match your personal style and taste. Also includes unique options such as brushed bronze, marble, rosewood, and more.
  • Timer – This allows you to set up a time in the future for the device to shut off. The timer function ranges between 2 to 12 hours. (See the differences section below for specifics on each BreatheSmart machine).
  • Forever Guarantee – Your air purifier is covered forever. If anything goes wrong with the internal components, Alen will replace the machine free of charge. (Filters are not included.)

Differences Between Each Alen BreatheSmart Model

As you read above, the main air cleaning functions of every Alen BreatheSmart air purifier are the same. That means you’ll get an equal amount of clean, fresh air from each device.

The differences between these machines, however, are much more subtle.

To save you countless hours of research, we’ve included an in-depth look at those differences in this Alen BreatheSmart review:

  • Ionizer Function (This boosts the air cleaning power by electrostatically charging air molecules.)
    • BreatheSmart FLEX is the only model without this feature.
  • Timer Function (Automatically turns the unit off after a specified time.)
    • BreatheSmart Classic offers 4, 8 and 12-hour timers.
    • All other models offer 2, 4 and 12-hour timers.
  • Child Lock (Locks the control panel so the settings can’t be changed.)
    • BreatheSmart Classic is the only model without this feature.
  • Room Size Coverage (The amount of space the air purifier can handle in square footage.)
    • BreatheSmart Classic = 1,100 sq. ft.
    • BreatheSmart FLEX = 700 sq. ft.
    • BreatheSmart FIT50 = 900 sq. ft.
    • BreatheSmart 45i = 800 sq. ft.
    • BreatheSmart 75i = 1,300 sq. ft.
  • Pink Noise (The fan sound is tuned to generate a soothing frequency that can help you sleep better.)
    • Only the 45i and 75i models include this feature.

Alen BreatheSmart Design and Size

From a quick glance, you’ll see that all of the Alen BreatheSmart air purifiers have the same general design.

Photo of Alen BreatheSmart Model ComparisonsThe only real difference is the roundness of the front panel corners and the actual size of each machine. But even then, those variations are subtle.

  • BreatheSmart Classic = 17.75″ (W) x 26.75″ (H) x 10″ (D)
  • BreatheSmart FLEX = 15″ (W) x 25″ (H) x 8.5″ (D)
  • BreatheSmart FIT50 = 16.75″ (W) x 22.25″ (H) x 10″ (D)
  • BreatheSmart 45i = 15″ (W) x 25″ (H) x 8.5″ (D)
  • BreatheSmart 75i = 18.5″ (W) x 27″ (H) x 11.5″ (D)

Unless you’re really tight for space in your home or apartment, these minor size differences shouldn’t impact your buying decision.

BreatheSmart Buying Recommendations

Overall, you can’t go wrong choosing any one of the BreatheSmart air purifiers.

But, for many people who are reading this review, the final choice will likely come down to square footage coverage.

  • If you have a small to medium size room (i.e. bedroom or living room), any of these models will work; however, for very large spaces (i.e. basement or open floor plan) you’ll likely need the BreatheSmart Classic, FIT50, or 75i since they cover the largest areas.
  • If you’re buying an air purifier for a bedroom, then the 45i or 75i are the better options since they include the Pink Noise feature.

If you have small children in the home, you can skip the Classic model and choose any of the others, since the Classic doesn’t have a Child Lock.

While the Ionizer function is a nice bonus to have, it shouldn’t be a dealbreaker because the HEPA filter is extremely efficient. So, don’t let the lack of that feature sway you from choosing the BreatheSmart FLEX if it meets your intended room size.

The small variation in timer hours between the BreatheSmart Classic and the other models is not that large. So, don’t let that impact your final decision either.
