Review on 🔘 BISSELL air320 Smart Air Purifier: HEPA & Carbon Filters, Large Room & Home, Bedroom Air Cleaner, Auto Mode - 2768A (White/Grey) by Drew Gengler

This air purifier has two major flaws and one minor flaw. A small downside is that the fan itself is noisy. That's something I like to overlook: it pushes out a lot of air. The two main downsides are the electric or engine hum when running, especially at low speeds, and the insanely annoying whistle/wind noise around the loose front grille as mentioned. other reviewers. These noises make it unsuitable for a bedroom, living room or office unless you have a hearing impairment. Otherwise, the device is quite attractive and easy to use. I could squeeze in enough foam to stop the whistling, but I don't want to start re-soldering capacitors on a new, expensive air purifier, so I decided to return it. The video attached to this review shows noise coming from the front grille and a hum coming from the top of the device.
