Literature referring to the ideal amount of negative ions

1. Effects on immune systems of humans and animals caused by air ionization

Ideal amount: 70,000-90,000 (pcs/cc)

Katsenovich and Kilichev confirmed in rheumatic heart disease and chronic meningitis patients that negative ions have microbicidal effects on neutrophilic leukocytes of the peripheral blood in 1962 and 1989, respectively.

2. Industrial and environmental engineering Vol.2, No.15

(Mitsuhi Abe) (1962)

Ideal amount: 20,000-300,000 (pcs/cc)

Air ion densities in this range are good for general air ion treatment(s).

3. Principal results of studies on air ions and hygiene - 5

(Moscow Medical School Laboratory of Stomatology)

Ideal amount: 10,000 (pcs/cc)

Air ions work not only when the density is high but also when the density is relatively low as found naturally in the air. Ions work most effectively when a person, who has no health problems, is exhausted.

4. Validity of the physiological effects of ionized air

Ideal amount: 5,000-500,000 (pcs/cc)

P.D.Ksenofontova discovered that air ion densities in this range improve immune competence in 1966.

5. Medical domain - theory and practice of air ion

(co-authored by Syouichi Kimura and Masahiro Taniguchi, published by Nanzando) (1938)

Ideal amount: 10,000-20,000 (pcs/cc)

A tuberculosis patient should absorb ions, which exist naturally in the air, for a long period of time for the treatment.

6. Medical domain - theory and practice of air ion

(co-authored by Syouichi Kimura and Masahiro Taniguchi, published by Nanzando) (1938)

Ideal amount: 20,000-200,000 (pcs/cc)

Ions in this range are good for general treatments.

7. Ideal amount of air ions for medical treatments

(A.L. Tchijevsky) (1960)

Ideal amount: 10,000-1,000,000 (pcs/cc)

Clinical trials are most often conducted in this range by researchers around the world.
