I have my Xaoimi in my bedroom with all doors and windows closed. If I open the ensuite bathroom door for just a few minutes the reading on my Xaoimi will change. Doesn’t this mean that it is detecting the bad hair from the bathroom? Which would indicate that it’s working well and doing it’s job?

You say that the Xiaomi works fine on high setting. How then is it possible that being used in a closed room on low or sleep setting will not give you the same clean air over time. Won’t it clean and re-clean the same air until no or few particles are left in the room. I just don’t understand why it would have to be on high setting to work effectively in a closed environment. I am in the market for an Air Purifier, and had pretty much decided on the newest version of the Xiaomi Pro, I am lost… Read more »

Won’t the technique of putting a fan with a strapped on filter cause the fan the break? I’m pretty sure normal household fan aren’t optimised for that much pressure as the filter requires a lot of pressure to push through. Wouldn’t it just break the fan after a period of time?

Hi! So this tests applies to the Xiaomi Mi Air Purifier PRO version? This one have a Laser sensor, and I’ve been reading is really accurate… Haven’t tried max setting much… I always use it on Auto Mode and always shows less than 20 or even 10 on the screen, I live in Coslada, Madrid, Spain.

I think that there is a problem with China limits… If you look to auto mode for Xiaomi it thinks that bad air is when PM2.5 daily averge are 75 (which is China limit), but in Europe f.e. the limit is 35… so Xiaomi leaves room with usafe air for europena standard but not for china standard. I think that it switches to lower power too soon for us, but not fot China limits (which is the country where it is sold officialy…). The right solution for Xiaomi should be a adjustable level for PM, but it needs a chenge… Read more »

My question is.. Why does particle count go up when air purifier slows down. Where do the particles come from if the room is closed?

Contrary to what Amin says, I’m told that even the Xiaomi 2s goes to auto mode after 3 hours. However, there is a fix! You have to use the smartphone app to turn it on to the high setting every 2.5 hours. For example, you set it to high at 9 a.m. and again at 11:30 a.m. and so on. Then it never goes to auto mode.

The new Xiaomi 2S (alongside the Pro and Max) use laser sensors instead of infrared to measure air quality. Would you mind testing the Auto Mode of one of those models?

I expect their measurements to be almost identical to those of your Dylos Pro.
So you could rule out Cause 1 and see of Cause 2 stands.

I have commented on your other posts as well. 1) dont rely on the auto mode. just set it to “favorite” mode at a reasonable level which isnt too loud. 2) to be clear, favorite mode allows you to set the speed exactly. the max speed in favorite mode is 34-37m2. However, if you go into the settings menu, you can enable turbo mode within favorite which allows you to go all the way up to 42-45m2. 3) for me, even the normal max speed (without turbo) is too loud. This is just a function of any purifier which is… Read more »
