Alen® HEPA Air Purifier Alen® BreatheSmart 75i

On Auto mode, a built-in dirt sensor or other inputs will allow the fan to run on a higher fan speed when the air is determined to be dirty and on a lower speed when clean. While the initial purchase price is hefty, the performance offered by the BreatheSmart 75i is outstanding. If you have a large space and need serious performance, this machine is up for the task. If you have a smaller space or are on a budget, other models will likely be better suited. Even if used continuously, running the purifier as recommended, Alen claims the filter will last 12 months.

It runs on average quieter than air purifiers with similar clean performance and is backed with a lifetime warranty as long as you purchase a filter subscription. While the BreatheSmart 75i isn’t too expensive lasko pedestal fans to run for a year in terms of electricity, you will need to replace its combined HEPA and carbon filter once a year. The capacitive control panel allows you to cycle through the settings easily.

Alen®’s BreatheSmart technology lets you monitor room conditions from your smartphone. We make the invisible visible, so you can verify that your units are removing harmful pollutants from your home – in one or multiple rooms. Designed to service rooms as large as 1,300 square feet, the 75i offers a beefy CADR of 347 cfm at the highest of five available speeds. (No breakdown for different pollutants is provided.) An option lets you turn on an ionization feature, in addition to the unit’s standard HEPA filtration system. If one of these fits in with your décor, it can certainly take some of the sting out of the dominating size of the unit. Just keep in mind that you’ll pay a $39 premium over the $749 asking price for any color aside from white.

I went for the ‘Fresh’ model, which contains a medical-grade H13 True HEPA filter plus an activated carbon filter for added protection against VOCs and smoke. ? The replacement filters are expensive.? The cheapest filter option doesn’t have an activated carbon filter.? Being provided with 3 different power cables for various regions is unnecessary and wasteful. Speed can be adjusted manually or using an automatic mode, and a countdown timer lets you shut the unit off after two, 4, or 12 hours.

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.

When he’s not putting a purifier through its paces, Paul likes to endlessly dig through dusty record shops (making his dust-free apartment even more important). Auto Mode intelligently adjusts its cleaning power to achieve the best air quality while maximizing air filter life while saving energy and money. Auto mode allows our intelligent sensor technology to adjust to your changing environment. LED indicator always lets you know the status of the air quality around you.

This is quite a long lifespan for a HEPA filter, with many other manufacturers suggesting replacing the filter after 6 months or a year if used infrequently. However, as the replacement filters cost up to $119, I hope it proves true. In reality, the power consumed will be much lower as the purifier operates on the lowest setting 99% of the time. Each of Alen’s True HEPA filters can capture 99.99% of airborne contaminants down to 0.1 microns, which are certainly impressive figures and was something we saw for real in our performance tests. However, these results reflect controlled lab testing, so I was keen to see how these figures translate in the real world. Once everything is unwrapped, open the front hatch via the air inlets on the side of the machine and slot in the HEPA filter, with the pre-filter facing towards you.

Even when set to the turbo, the BreatheSmart 75i produced very little noise. In this setting, it omits a pleasant low hum that our testers found to be noninvasive white noise. When running on medium, it was even quieter, and it was all but unnoticeable when set to low. While the 45i proves to be highly efficient in energy use, filter replacement costs are considerably increased by average running costs.

The 75i gets quite loud when things start running at higher levels; I often ended up manually turning it down to quiet the room. This review is part of TechHive’s in-depth coverage Lasko Box Fan of the best air purifiers. Long-lasting True HEPA (H13) filters remove 99.99% of airborne contaminants down to 0.1 microns, including allergens and aerosolized viruses.
