Ultimately, this means that this is an exceptional option for large rooms. I’m pleased to say it has lived up to the expectations of an Alen product. With four fan speeds to choose from, the noise of this purifier can easily be curtailed to suit the user while still vastly improving the air quality in your home. This lets you alen breathesmart turn the machine to “auto” and will kick on if the room’s air quality dives below a certain measurement. This function works in tandem with an LED light ring that changes color as the air quality improves or worsens. It can be set to run in increments of two, four, and twelve hours and has five different speed options.
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 Box Fan 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.
Its intuitive design, whisper-quiet operation and a lights-off mode for sleeping make it a superb choice for large bedrooms as well as open concept rooms. Child-friendly features include a locking control panel and child-safe vent guard alen breathesmart make it THE choice for homes with kids or grandchildren. The unit is whisper-quiet at its lowest speed, but in automatic mode I found the unit rather aggressive at ratcheting up the speed, even when particulate levels were low.
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 Alen Breathesmart 45i proves to be highly efficient in energy use, filter replacement costs are considerably increased by average running costs.
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.
