Guide for the best negative ion generator:

It must be tough for you to believe that the negativity is only limited to the name. Ironically, these ions attract the air-impurities that are in the form of positive ions. When the negative ions stick to the positive ions, they become so heavy that they collapse and fall on to the floor, resulting in a purified air.
Studies suggest that apart from purifying the room air, these ions do an amazing job at increasing the oxygen level in human blood that adds to the immunity & metabolism of human body. Exactly why they are termed as the air vitamins in scientific circle.

There are a few other effects of negative ions as well and are as follows,

  • Kills viruses
  • Removes pollutants
  • Reduces anxiety
  • Promotes plant growth
  • Reduces the heartrate (resting)
  • Improved sense of well-being
  • Active mind

Other than the researches have shown that the negative ions can also improve the:

  • Skin Health
  • Mental performance
  • Sleep quality
  • Physical performance
  • Concentration level

Therefore, getting a negative ion generator can bring many positive changes in your life and can make a huge difference to your health condition.
