To you and me, that ranges from a whisper on the lowest level to a box fan on the highest. This was the same time as the Levoit Core 400S and the budget TaoTronics AP-003 but 3 minutes quicker than the Mila Air Purifier. The 45i has great performance for a smaller to a medium-sized room but would not be the best choice for a larger room, which is why the Alen 75i exists, which managed to clean our alen breathesmart test room in 24 minutes. The Alen Air mobile app offers all of the onboard features and more, at least once you manage to get to them. The lengthy setup process includes more onerous security than my bank account, but while the process is a hassle, I completed it without any hiccups. This gargantuan purifier is best suited for commercial environments, but it really shines when it comes to power.
Its smaller brother, the FIT50, shares similar design styles and capabilities and effectively cover medium-sized rooms such as your family room or master bedroom up to 900 sq ft. Onboard controls are basic but functional, including a color-coded ring around the power button that indicates one of five levels of particulates in the air. The front panel pops off to reveal a large HEPA filter (no rating specified) underneath. Air is pulled in from around the sides of the panel, through the filter, and emitted through a large grille on the top of the device. A child-friendly vent guard attachment is also in the box if you’re worried about Junior sticking a hand inside.
Alen’s BreatheSmart 75i is the company’s largest air purifier, and it’s one of the largest I’ve tested altogether. The 75i is also quite powerful–indeed, maybe too powerful for most residential users, making it a better fit in commercial venues. Our experts test thousands of products each year using thoughtful test plans that bring out key performance differences between competing products. And, to assure complete independence, we buy all the products we test ourselves. Reflects how intuitive and easy the controls are to use, carrying ease, ability to remove the filter, and filter life indicator.
To measure the amount of electricity used, we hooked the device up to a watt reader and recorded how many kilowatts per hour it used while running on a medium setting. Assuming 12 hours of use per day, it costs around $9.00 to run the BreatheSmart 75i for a year. While quite a few devices were cheaper to run, this was nowhere near the highest annual cost. For those looking for a quiet and powerful purifier for under $450.00 and are happy to pay extra for the lifetime guarantee and smart features, the Lasko Box Fan 45i could be the air purifier for you. The app isn’t the most intuitive, in part because it seems to be designed to service multiple devices instead of just one. All status indicators include the number of devices which are in the given state, so you might see “1” running, “1” with “blue” air quality, and “1” with good filter life.
While it is equipped with handles, it weighs a whopping 27 pounds, which makes it a little more challenging to relocate. We use a Purpleair Indoor sensor with our in-house custom API recording software and then share this data Lasko Box Fan via Flourish. Consumer Reports recommends the Alen® BreatheSmart 75i Pure with an overall EXCELLENT score. Alen® air purifiers are engineered to outperform by combining power with efficacy and superb filtration technology.
The first was making sure that the CADR (clean air delivery rate) number provided by the manufacturer was verified by AHAM (Association of Home Appliance Manufacturers). This ensures that the machine’s efficacy has been verified by a third party; not all air purifiers go through this outside verification. The BreatheSmart 75i has the AHAM stamp of approval and is capable of cleaning 400 cubic feet of air per minute.
