Review on Holmes Small White True HEPA Air Purifier by Bima ᠌

I just bought it today, so it's too early to talk about air purification. The air pollution sensor works great. But Alice can only be turned on, off and on for a certain time, you cannot switch modes. I chose between 3C and 3H, the difference of 3H shows humidity and temperature, but it’s stupid to pay an extra 8000 for this. I immediately ordered cotton covers for the filter on Ali, they should extend the operation of the filter.
