Review on 🌬️ LEVOIT Air Purifiers for Home Large Room with Smart WiFi, H13 True HEPA Filter, PM2.5 Monitor, and Alexa Control - Removes 99.97% of Particles, Allergens, Smoke, Dust - Auto Mode, White by Lori Wybenga

The noise level is pretty quiet for the amount of air it moves. It's quite large, but not so heavy that it's difficult to move. Works great for air filtering. I liked it so much I bought a second one for my mum a few days later when she was complaining of allergies. Filter. If you forget to do this, it will run with no filter installed. All in all, the quick setup takes less than 2 minutes from opening the box to starting the machine. This is a simple 5 star rating. There was one downside. When I checked out the app, I wasn't interested in accessing almost anything on my phone (and with no explanation). I have other smart devices that require much less access to my phone. I didn't finish using the app as I decided it's better to just use clear and obvious buttons at the top than give the app so much control. I think this is because the application can be used not only to control the air purifier but also for other purposes. On the other hand, I only want to use it for the cleaner.
