humidifier cleaner

As Raynear mentioned humidifier can make air pollute by lots of germ. So we need to keep the humidifier clean very carefully. But it is hard.

I found a good item for this purpose: Humidifier cleaner.It makes it easy to keep clean.

However, despite the efficiency, we cannot omit to rube the inside of the humidifier and carefully wash it often. It is not perfect remedy.
