The king of open-concept spaces air cleaning. Alen BreatheSmart 75i air purifier is a welcome introduction to owners familiar with 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 front panel if you need to freshen the looks. 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 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 Smart sensor, Sleep mode activates automatically when the lights are out. You can check out the room air quality via the color rings surrounding the power button. Blue = Excellent clean air, Green = Good, Orange = Fair, Red = Poor, Purple = Bad dirty air.

That’s not all, other passive features of Alen BreatheSmart 75i including 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 properly closed. It is also UL listed, CARB approved ozone-safe that produces less than 0.001 PPM with ionizer engaged. 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

Advanced medical-grade HEPA filtration according to your needs. By default, Alen BreatheSmart 75i air purifier comes with an antimicrobial H13 True HEPA Pure filter that removes 99.99% of airborne particles down to 0.1 microns. It will effectively capture dust, hair, mold, mildew, pollen, pet dander, germs, and bacteria that passed through. For extra 20 dollars, you can upgrade to a HEPA fresh filter that removes allergens with the addition of smoke and odors from cooking, cigarette, VOCs, chemicals aerosol sprays. For extra 30 dollars, you can get a HEPA Pet filter that specialized in capturing pet odor and pet dander or HEPA heavy odor that focuses on heavy odors including baby diapers. There is also an ionizer that releases negative ions to attract positive ion pollutants in the air. The combined particles will fall due to the increased weight allowing the HEPA filter to capture.

^ Replacement filters/ estimated cost
All the impressive features and performance comes at a cost. In Alen BreatheSmart 75i case, +- 749 excluding any discounts or promotional deal. While it is 50-100 dollars more than the classic BreatheSmart, the improved airflow performance itself is worth the extra cost. For those that are looking for more cost-effective options, you could opt for the lower variant e.g. breatheSmart 45i, Flex, or Fit 50 that offers the same features but with a lower output.
Being the best seller model, Alen BreatheSmart 75i is available at Amazon at a slightly discounted price. There are also perks to enjoy like bundled deals, free shipping, and 30 days no questions asked return policy guaranteed. Official Alen's webstore is doable as well but you will have to go through the hassle of creating an account and the discount is seasonal. So far we have not spotted Alen products in our local retailers but do check back from time to time.
