I bought this air purifier after reading this article and researching more. The biggest advantage of this air purifier compared to others on the market is its cost of replacing the air filter. It's significantly cheaper than others. I stay in a city with considerably high air pollution 2/3rds of the year, and this has done a wonderful job of cleaning the air. Plus, Ikea sells a tiny air quality sensor separately, so you can measure the quality of the air near where you're sitting, not where the purifier is.
