Years ago, I have frequent itchy nose so I bought a Sharp Plasmacluster. The itch did went away and my house was less dusty. Hubby did an experiment where he fart near the purifier and the light indicator really did went from green to red (means there's pollutant) . It does clear off the smell from my cooking rather fast.

But.... when the hepa filter expired and I tried to buy a new one, surprise! The electrical shops I went (Harvey Norman, Best Denki etc..) all not interested to help me to order a new one. I guess no commission for them for refill parts? Now I have a monster machine in my house that cannot be used.
