IONEX Air Ionizer - Black

I use it for my dust, pollen and mite allergy. I followed the instructions how to excercise the negative ion therapy and I inhale negative ions every day. I must say, my allergy has disappeared since!The air is also fresh and visibly cleaner, so I have it turned on at all times. You can see the pollution from the air gather around it as a greyish dust.It doesn't need any replacements or additional purchases. The maintenance is also an advantage, I just wipe it with a soft cloth once a week.Simple!
