#6 I must have a good air purifier at home 01 November 202201 November 2022 by Yiu Fung YIPin Featured Peter: Hi Jennifer, I heard that you moved into a new flat! Congratulations! Jennifer: Thanks Peter! But we are still setting up the space. Do you have a good air purifier to recommend to me? Peter: You could buy a medical grade air purifier used in hospitals. Why exactly do you want one? Jennifer: Nowadays everybody gets one. It purifies the air as its name suggests.Peter: It might be misleading, all it doesn’t magically make the air pure. It treats some of the issues. But you need to know what issues appear in your home to select the one with the right filters. Jennifer: Ah, I thought it is kind of mandatory to have at home to clean the air. That is how the advertisements say.Peter: I would say it is on a case-by-case basis. Some homes got formaldehyde from the paints, some got high particles because of nearby road traffic. It is better to understand the air quality before deciding which purifiers to buy. Jennifer: You are right! Maybe I should get a monitor to check if the air is safe first!
