I recommend to use Hepa filter on the Xiaomi filter in Xiaomi purifier, to incense the lifetime of the filter.

You can see after some months , depend your environment , the color of the filter . Check at the end of the video the filter after some renovation works.

I like the purifier, the home have less dust and dust mite, if you have allergy, it highly recommended !
