And our beautifully designed, whisper-quiet units do it without disrupting your conversations or your lifestyle. While we all want to be in a room breathing clean air, some machines are simply too noisy and distracting to make it feel worthwhile. In order to see just how noisy each device was, we turned each one on and measured the sound output with a decibel reader.
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 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.
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.
By putting it through its paces in various real-world tests, it proceeded to tick all the boxes. Working well at eliminating odors from cooking and nearby breweries and noticeably reducing allergies to pollen and dust while being extremely simple to operate and maneuver around the home. Alen states the sound levels of the purifier are 39 dB at speed 1, 42 dB at speed 2, 49 dB at Speed 3, and reaching 55 dB on turbo.
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 Lasko Box Fan 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.
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 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.
Ranging from $69 for a basic filter to $119 for the premium option, this is a notable expense to be paid out and should be seriously considered before purchasing. Running this air purifier will cost less than you think, thanks to its Energy Star-rated efficiency – even if you leave it running on auto mode around the clock, as Alen recommends. During the day, with the purifier set to auto, it occasionally ramped up the fan speed to higher levels. This creates a lot of noise and can be distracting, especially if working or even watching TV or listening to music. Of course, this can easily be adjusted to suit the user and limited to lower speeds when needed. His apartment has become a de facto HouseFresh test lab where he pits the latest clean air technology against the perils of city center life.
