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 pedestal fans 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.
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.
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 Lasko Box Fan 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.
