Review on 🌬️ Winix A231 Tower H13 True HEPA 4-Stage Air Purifier: Efficient Home/Office/Nursery Solution, White/Charcoal Grey Small by Amber Powell

At first I was very excited about this, but the first sign something was wrong was that there was no instruction manual in the box. The only instruction I got was a yellow piece of paper with a photo showing how to open the air filter. The filter worked fine for about 10 hours, then for some reason turned red (poor air quality) and stayed red for another 3 hours. I opened the windows, took it to another room and then spent 20 minutes on the internet looking for an instruction manual on what to do. I didn't find anything that helped so I'm sending it back now. Damn shame.
