Thanks for the link.
I read this site before - A bias review cleverly written by someone that sells their own brand of air filters
If you read the whole article properly, which the writer hopes you don’t, it says and I quote,
QUOTE
“From this data, my conclusion is that the fan and the filter are fine, but the Xiaomi air purifier has a programming flaw. Even if I use it on the highest setting, I’ll be breathing air far above the safe limit for most of the night. That’s a problem.”
The problem was that he set the Mi air filter to High but after three hours, it set itself back to Auto Mode which reduces the whole air flow. The way he wrote the whole review with big words of how unsafe it is, that makes you and other readers conclude that the Mi filter is no good and unsafe but actually he is only complaining about the auto mode, that he can’t set it to High for more than 3 hours. Only one small line he mentions that there is nothing wrong with the filter itself or the fan which is fine.

“How often is the air unsafe?
I calculated the percent of hours that the air was unsafe during the tests using this rule:
After the purifier was on for at least 1 hour, for any hour where outdoor air pollution was unsafe (> 25 micrograms – the WHO 24 hour limit), how many hours was indoor air also unsafe (>25 micrograms)?
The Xiaomi purifier left air unsafe for a shocking 86% of the time. The other similarly sized machines in my earlier tests left air unsafe only 7-16% of the time.”
Anyway I can tell you, the Mi Air Purifier 2S can stay in manual model, set to High if you want. It doesn’t drop to Auto Mode on its own. But totally unnecessary as it has a PM2.5 counter. If the air is already clean, I don’t see why it needs to stay in High Mode but you can if you want.
