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.
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 alen breathesmart 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.
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 alen breathesmart 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.
When we switched on the Alen 45i at full power with the ionizer, it removed all particles in 33 minutes. When purchasing the Alen Breathsmart 45i, you are given a range of filters. Each filter offers a slightly different level of protection, mainly in relation to odors and volatile organic compounds (VOCs). With customizable designer panel colors, the BreatheSmart can be personalized to fit any room and compliment your decor for today or whenever your styles change.
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 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.
