Introduction

What are Negative ions?

Negative ions are odorless, tasteless and invisible molecules that we inhale in abundance certain environments. Eg. Mountains, waterfalls and beaches.

• The main differences in the air between healthy outdoor environments and unhealthy or harmful outdoor environments are the levels of negative ions, ozone, and pollutants.
• Healthy environments have higher levels of negative ions, moderate levels of ozone, and low levels of particles and/or pollutants. Unfortunately, most indoor environments are more similar to unhealthy and hazardous outdoor environments.
• The negative ion concentration in most indoor environments is between 100 and 200 negative ions per cubic cm. In healthy and invigorating environments, such as near a large waterfall, the negative ion level is around 1,000,000 per cubic cm, which is the level produced by our “M.Frea“ personal air purifier.

As an example, in healthy outdoor environments such as in the mountains, or in a country meadow, the negative ion concentration is typically 2000 to 4000 negative ions per cubic centimeter.

• Very low levels of negative ions are found in enclosed spaces, cramped rooms with poor ventilation, congested heavy traffic etc.

* Do you know?

Nature provides us with negative ions which produces therapeutic effects on humans

How does Negative (-) Ions Purify the Air?

• Virtually all particles in the air have a positive charge, while negative ions have a negative charge. In which case, negative ions and particles magnetically attract to one another. When there is a high enough concentration of negative ions in the air, they will attract to floating particles in large numbers. This causes the particle to become too heavy to remain airborne. As a result, the particle will fall out of the air, preventing it from being inhaled into the respiratory tract where it can trigger breathing and health problems.
• The ionized particle will then be collected by normal cleaning activities, such as vacuuming or dusting. If the particle happens to be kicked back up into the air again, it will be ionized, and quickly settled out of the air once again.
• This is why indoor environments need a source of negative ions. In addition to being beneficial to your health when occurring at proper levels, they are highly effective at removing particles and contaminants from the air, which results in a much healthier environment by itself.
• In nature, negative ions are generated by processes such as sunlight, lightening, waves from the ocean, and from waterfalls. However "Concrete Jungles" minimize the natural production of negative ions by disrupting the delicate electrical balance between the atmosphere and the earth.
