I have the follow information regarding ion count in the air for your information as according to Asian Medical Journal.
The amount of negative ion (Per 1cc of air):
1000 to 2000 it is goo for your health.
5000 to 50,000 it strengthen our body's resistance and improve immunity.
100,000 to 500,000 helps our body to self-heal (improve illness)
The largest organ in our body is our skin. We are only able to absorb 15% of negative ions through breathing. If we use our skin to absorb negative ions, the efficiency rises to 85%.
Therefore, our body can absorb 100% of negative ions if we wear Teviron garments.
"The normal Ion count in fresh country air is 2,000 to 4,000 negative Ions per cubic centimeter (about the size of a sugar cube). At water falls, you'll experience over 100,000 negative Ions per cubic centimeter. On the other hand, the level is far below 100 per cubic centimeter on the expressway/freeways during rush hour."
Recently I had purchased the following Forest Anion USB ion generator from the PC show for only $10, it was really worth it. Whenever I use my computer I will plug in my USB ion generator to generate all the negative ions in the air. However our human body can only absorb 10-15% of the negative ions thru' breathing, 85% thru' skin, thus by wearing Nefful negative ion clothing, we are absorbing 100% of the negative ions in the air.
Doing some research on Forest Anion, I found the following presentation in YouTube website and wanted to share with you so that you may consider using a Forest Anion lamp to help you remove Positive ions in your room.
