asked

I want to buy a couple of portable air purifiers to send to Shanghai, where the air quality is poor with high AQI indices and significant smog. I am considering brands like Aprilair, Alen air, Austin Air, and IQAir. I am looking for the best possible unit that can handle dust, smog, and various pollutants, even if the price is high. What are the best options available, and how do these brands compare in terms of effectiveness and reliability?
