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.
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 lasko pedestal fans 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 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.
You have to drill down to an individual device to access its controls and a detailed graph of both indoor and outdoor air quality history. When testing each machine’s ease of use, we looked at a couple of key features. First, we timed how long it took to get the device out of the box and set it up. It took our testers about five minutes to get the BreatheSmart 75i up and running, which is pretty average when compared to most other models.
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, lasko pedestal fans 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.
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.
The next step was sealing up our 150-square-foot testing room and filling it with smoke by burning paper and other testing materials. We monitored the air with a Dylos air quality monitor; once the room reached our desired level of airborne particulate pollution, we kicked on the BreatheSmart 75i for an hour. After 30 minutes, there were only 16.62% of the original particulates left floating in the air, .003% after 45 minutes, and 0 detectable particulates after an hour. While the odor from the burnt paper wasn’t entirely eliminated, it was severely reduced.
