The king of open-concept spaces air cleaning. Alen BreatheSmart 75i air purifier is a welcome introduction to owners familiar with the Alen lineup. To start with the design, the clean, interchangeable front panel is proportionally shaped with no sharp edges. You can effortlessly swap out the many customizable front panels available online if you need to freshen the looks.

Alen BreatheSmart 75i Control Panel

At an 18.5 x 27 x 11.5 inches in dimension, it is not the smallest but still perfectly usable even for a small home. Weight-wise, the 27 pounds can be hard to move around, especially without casters. Fortunately, there is a carrying handle that you can grab onto when needed. The Air inlet is located on both sides, while the air outlet is at the usual top spot. Even though we had it for less than a month, the durability and reliability are top-notch similar to all the top brands. Alen BreatheSmart 75i is also made here in the U.S.

Alen BreatheSmart 75i smart touch control configuration is clear and precise that you would expect no less. You can cycle between the 5 fan speeds (including Turbo), reset the filter indicator after replacing the filter, or set the 2, 4, 12 hours timer. You can also activate/ deactivate the ionizer and auto mode that automatically adjusts the fan speed to high or low depending on the room air quality. With the help of the Smart sensor, Sleep mode activates automatically when the lights are out. You can check out the room air quality via the large power button’s color ring that illuminates as such:

  • Blue = Excellent clean air
  • Green = Good
  • Orange = Fair
  • Red = Poor
  • Purple = Bad dirty air

Other passive features of Alen BreatheSmart 75i include a child lock that prevents children from meddling with the control and a child-safe vent guard that stops the air purifier from running when the panel is not closed correctly. It is also UL listed, CARB approved ozone-safe that produces less than 0.001 PPM with ionizer engaged. Made entirely in the U.S., you’ll also enjoy Alen’s lifetime warranty as long as the product is officially registered and comes with an active filter subscription.

Filters And Performance

Four different advanced medical-grade HEPA filtration to help with your respiratory issues. By default, the Alen BreatheSmart 75i air purifier comes with a long-lasting, antimicrobial H13 True HEPA Pure filter that removes 99.99% of harmful airborne particles down to 0.1 microns in size. It will effectively capture dust, hair, mold, mildew, pollen, pet dander, germs, and bacteria that pass through the filter. The antimicrobial coating stops captured germs and pathogens from growing in the filter. For an extra $20-30, you can upgrade to Pet, Fresh, Heavy Odor as such:

  • HEPA fresh antibacterial filter - Removes allergens with the addition of smoke and odors from cooking, cigarette, VOCs, soot, chemical aerosol sprays.
  • HEPA pet antibacterial filter - Specialized in capturing pet odor and pet dander on top of microscopic particles.
  • HEPA heavy odor antibacterial filter - Removes allergens and strong odors, including baby diapers.

There is also an ionizer that releases negative ions and creates a static charge to attract positive ion pollutants in the air. The combined particles will fall due to the increased weight allowing the HEPA filter to capture.

Alen BreatheSmart 75i does an outstanding job cleaning the air and protecting your health. Within hours of running Alen BreatheSmart 75i under an unhealthy air quality condition, you can sense improvement in the air that feels fresh and much easier to breathe. You will sleep better and wake up with no stuffy nose, dry cough, watery eyes, breathing issue, or itchiness due to allergens. Perfect for a household with hypersensitivity/ asthma person, children, elderly, and/ or indoor dogs and cats.

A quiet and powerful large room air purifier, Alen BreatheSmart 75i noise level is well-suppressed at 25 dB lowest speed to 49 dB at highest speed. Even running at max speed, expect a comfortable rainfall equivalent pink noise frequency to help you sleep better, unlike the abrasive white noise. The WhisperMax technology filtration system is also ideal for living room, office, or classroom use that needs quiet air cleaning performance with minimal noise disturbance. You can enjoy clean air that helps boost concentration levels and productivity.

As an Energy Star certified model, Alen BreatheSmart 75i power consumption is justifiable at a max of 45 wattages per hour with only 1.8 wattages on standby. With daily 12 hours of operation, expect an estimated low running cost of $0.08 a day, $2.43 a month, or $29.16 annually in electrical bills. Double the cost if you intend to run it 24 hours a day.

All the impressive features and performance comes at a steep price. In Alen BreatheSmart 75i case, +- $749 excluding any discounts or promotional deal. While it is $50-100 more than the classic BreatheSmart, the improved airflow performance is worth the extra cost. You're getting an extended filter life and Alen's lifetime warranty as standard. Save a good chunk of money in the long run without constantly replacing the filters. The annual filter cost is around $66-99, depending on the filter set. Alen charges B7-Pure filter $99, B7-Fresh for $129, and B7-MP-Pet/Odor for $139. To enjoy even greater savings, you can also opt for the Alen filter subscription to save 5% on filter cost. For those looking for more cost-effective options, you could opt for the lower variant, e.g. breatheSmart 45i, Flex, or Fit 50, which offers the same features with a lower output.

Alen BreatheSmart 75i

Being the best seller model, Alen BreatheSmart 75i is available at Amazon at a discounted price. While it is still expensive, you can finance it through different channels with a monthly payment as low as $63. There are also perks like bundled deals, free shipping, and a 30-60 days no-questions-asked return policy. Official Alen's web store is doable with seasonal discounts, an attentive customer service team, and "60 Day Love It, Or Return It" guarantees, though you will have to go through the hassle of creating an account and tracking it. So far, we have not spotted Alen products in our local retailers but do check back from time to time. If you are pondering for BreatheSmart 45i, we would highly suggest you opt for the slightly expensive 75i for the superior room coverage with no extra noise output to compromise.

Alen BreatheSmart 75i VS The Challengers

Coway Airmega 400 Review

Coway Airmega 400

Cheaper by 300 with identical airflow output and applicable area. However, it lacks an ionizer feature and comes with a different filtration setup.
Rabbit Air MinusA2 Air Purifier Review

Rabbit Air MinusA2 SPA-780A

Mountable air purifier with a cheaper price tag and a more comprehensive 6-stage HEPA filtration. You do have to settle with an inferior airflow output and CADR.

Final Thoughts On Alen BreatheSmart 75i

Alen BreathSmart 75i is a solid upgrade from the BreatheSmart series known for its trusted filtration system and customizable setup. The 99.99% particles removal efficiency does a splendid job keeping allergies down. However, there is a hefty price to pay and a large body that can be intimidating in a small room. If you can look past the drawbacks, you will be rewarded with all the smart features, auto cleaning mode, and lifetime warranty in the deal. For those with a large family, a company with more than 5 workforces, or a classroom packed with students, Alen BreathSmart 75i is a sensible choice.

Pros

  • The widest and strongest airflow performance in the Alen BreatheSmart series. Cleans up to 1,300 square feet of room space.
  • All upgradable H13 HEPA filters come with antimicrobial treatment to prevent microorganisms' growth.
  • Ionizer that can be disabled for complete Ozone-free purification.
  • Longer-lasting filter that can last up to 18 months on normal use.
  • Child lock, 5 speeds (with turbo), Auto/ lights-off mode powered by the newer intelligent sensor.
  • Pink noise operation with minimal disruption even on the highest speed.
  • Guaranteed for life when used correctly (registered, active filter subscription, no counterfeit filters).

Cons

  • Expensive (above $700 price point) for this top-of-the-line model.
  • No smoke, chemical, or odor filtration on the basic HEPA Pure filter. You will need to upgrade to Fresh/ Pet/ Heavy Odor to remove gaseous pollutants.
  • Uses an all-in-one filter set that cannot be replaced individually. Fortunately, filter cost is still within a reasonable realm.
  • Bulky and heavy, which limits the places you can place the air purifier.
  • Wi-Fi support would be a nice touch for its price range.
