I really like this air purifier! It has a ton of features and the display is really easy to read and use. My favorite part is the fan speed setting. I also love the sleep mode because it turns down the fan and turns off the display lights while you sleep. There is a timer option so you can cycle through different hourly options. The setup was super simple. Just remove the filter cover and take off the plastic packaging and reassemble. I also downloaded the VeSync app so I can control the purifier from my phone! Perfect for those times when you want to make sure the air is nice and purified for company but you're not at home yet. My only negative comment is that it is pretty big and bulky.
