Speaker2: I wanted to show you what I bought
Speaker2: <file_other>
Speaker1: Air purifier! Well done.
Speaker2: This one removes not only PM2.5 and PM10 but also dust and mites.
Speaker1: Is it quiet? I'm not sure how loud 31dB is.
Speaker2: Its' almost impossible to hear it working.
Speaker2: But it has three different modes and if you want it to clean the air quickly then it's like a computer's fan.
Speaker1: You almost convinced me to buy it. I'm going to read more about purifiers now.
Speaker2: If you need any help or advice, just let me know.
Speaker1: Thank you and have a nice day.
