Review on 🌬️ GermGuardian AP5800W: Superior 19" Hi-Performance Air Purifier with HEPA Filter & Air Quality Sensor in White by Scott Welch

This is quite a large and powerful air purification tower that works very well. Build quality and performance are excellent. I really like the "Auto" function, which detects the air quality and automatically adjusts the fan speed. This allows me to "set and forget". I just leave it on automatic all the time. It runs on low settings most of the time and is inaudible unless you get your head closer than 2 feet to the device. If the air quality then changes, e.g. if there is smoke while cooking, it will shift into a higher gear to circulate more air through the unit until it senses the air quality is good again, and then back up. to a lower calm attitude. This device is a little pricey, but it's worth it if you want a powerful air purifier that works well.
