We reviewed the highly effective and unusually massive BreatheSmart 75i air purifier lower than a 12 months in the past. Since then, it has obtained key enhancements, together with improved elements and an up to date consumer interface, which deserve one other look.

Recapping ours previous review, the 75i is a real HEPA air purifier designed for residential or industrial use. The latter looks as if a extra doubtless state of affairs given the equipment’s 27 x 19 x 12-inch (HxWxD) measurements and its capability to serve rooms as much as 1,300 sq. toes. A pair of wheels on the again make shifting the 27-pound unit barely much less cumbersome.

Design and performance

Between its imposing measurement and a big entrance panel that grabs your consideration, the 75i is not a purifier you’ll be able to simply disguise in a nook or underneath a desk. Luckily, there are six totally different shade choices: white, oak, weathered grey, brushed metal, graphite, and espresso, which might help the unit mix in additional simply together with your decor. Keep in thoughts, nonetheless, that any shade aside from white will add an extra $39 to the $749 worth.

The identical issues that make the BreatheSmart 75i a troublesome promote for residence customers — its measurement, its app, its excessive asking worth — make it well-suited to industrial environments.

Size apart, the 75i works like a typical air purifier. A big HEPA filter is pre-installed in a compartment behind the entrance panel. Air drawn in by slots on either side passes by the filter and is dispersed by a vent on prime. The unit contains a air flow guard to maintain curious kids’s fingers secure.

This overview is a part of TechHive’s in-depth protection of the the best air purifiers.

The 75i boasts 5 speeds, the very best of which affords a CADR (clear air supply fee) of 350 cfm (cubic toes per minute). CADR is an authorized score that signifies an air purifier’s effectiveness by measuring air quantity in cfm with separate scores for smoke, pollen, and dirt. Alen does not present a breakdown for these totally different pollution, however for the reason that score scale solely goes as much as 400-450 relying on the pollutant being measured, the 75i’s mixture score appears strong.

The “Pure” filter included commonplace with the 75i is a typical HEPA H13 air filter able to trapping frequent pollution comparable to allergens, mud and mildew. Other choices embody “Fresh,” which provides a carbon filter for odors and VOCs, and “Pet,” which neutralizes pet odors and captures hair and dander.

The filters have a most lifetime of 15 months. Filter replacements price $99 (Pure), $129 (Fresh), and $139 (Pet) every, however a filter subscription shaves 10% off the worth.

The unit could be operated through a contact panel on the highest. Controls are primary and embody a color-coded ring across the energy button that signifies the present air high quality primarily based on the extent of particulates within the air, handbook and automated velocity modes, an ionizer, a baby lock, and a button that adjusts the brightness. of the ring indicator.

App options

All these controls are mirrored within the Alen Air cell app, which can be utilized to remotely management the 75i and monitor air high quality in additional element. The setup course of appears extra streamlined than the final time we examined this product and solely took a few minutes to finish.

The fundamentals of the app are nonetheless the identical. Since it was designed to handle a number of purifiers, the app’s dashboard reveals the variety of gadgets in every of the three indicated states: working, idle, and disconnected. Tapping any of those three states takes you to a display screen that lists particular gadgets, the place you’ll be able to filter them primarily based on variables like air high quality, filter life, and system sort.

Once you choose a person system, you’ll be able to entry its controls and information. It looks as if that is the place quite a lot of enhancements have been made to the app. In addition to air high quality shade scores, now you can drill down into particular pollution together with particulate matter, risky natural compounds, and carbon dioxide, in addition to indoor temperature and humidity. The app offers on the spot readings for every of those, in addition to a straightforward method to view previous ranges on a brand new 60-minute chart that updates each minute.

Another new function is the potential for downloading sensor information. This function, accessible from a three-dot menu on the prime of your system’s dashboard, lets you e-mail your self a .csv file containing historic information factors for every of the pollution monitored by the purifier. It’s exhausting to think about a house consumer needing information of minute-by-minute air high quality readings until they’re notably nerdy or are coping with one thing particular like a humidity drawback, however I can see them being helpful in a industrial surroundings.

App controls can now be accessed by tapping the distant icon on a person system’s dashboard. This prompts an overlay with a picture of the unit’s built-in management panel with fan speeds and different controls displayed beneath it.

While I nonetheless would not name the app intuitive, it offers pretty clean operation of the 75i when you get your bearings. And Alen says extra enhancements are on the way in which, together with the flexibility for customers to create customized applications for his or her purifiers.

Should you purchase the Alen BreatheSmart 75i?

The 75i is a strong air purifier, maybe too highly effective for residence use. It actually saved the air in the home cool, however testing it in my front room, I discovered it too massive, too ventilated, and too loud at greater speeds for my liking. I actually cannot think about putting in it in a smaller area like a bed room or residence workplace.

But the identical issues that make it exhausting to promote to residence customers — its measurement, its app, its excessive asking worth — recommend it is higher suited to industrial environments. With the push for cleaner indoor air in workplaces, it is simple to see it utilized in a small workplace or physician’s workplace the place air high quality must be monitored extra carefully and managed extra aggressively. If you will have such a use case, the 75i is perhaps answer.
