WINIX 5520 Air Purifier for Home Large Room Up to 1881 Ft² in 1 Hr, True HEPA with WiFi

I bought this purifier because I saw a good review on its performance and it was a good price at Walmart. Seems to be doing its job. Has an air quality indicator light to let you know if the air is good, fair or bad. Easy to change filters. Very quiet compared to my other purifiers, even on high. It is however larger than my other air purifiers, so it takes up more space, and sits on the floor.

I've had 3 of the Winix 5520 for a while now and honestly it's been one of those purchases where you kinda forget it's there because it just does its job. What I like most is that it automatically adjusts to the air quality without me having to mess with it. If we're cooking, spray cologne or something in the house, or even kick up dust cleaning, you can literally hear it ramp up on its own and clear the air out pretty quick. It's also super easy to clean and maintain. Popping the filters out and cleaning things up takes almost no effort, which matters because if something is annoying to maintain, most people eventually stop doing it. Only real downside I've found is the Wi-Fi. If you manually power it off and back on like if you open windows for the day and shut it down it makes you reconnect it to Wi-Fi again, which gets a little annoying. Overall though, I'd buy it again. It's been solid, works without me constantly babysitting it, and you can genuinely notice the difference in air quality.
