The BioSmart® Far Infrared Heater does not use up oxygen or dry out the air, nor does it produce positive ions like other blower type heaters.  And the BioSmart® Far Infrared Heater does not destroy healthy negative ions -- it actually produces them. Since the early 1950s scientists have suspected that ions play an important role in how the body functions and, consequently, in how we feel.  Research has shown that an abundance of negative ions in the air we breathe is highly beneficial.

Conversely, scientists have found that if the air is charged with too few negative ions and too many positive ions, we become anxious, fatigued and tense. Positive ion poisoning has, in fact, been linked to heart attacks, aggravated asthma, migraine headaches, insomnia, rheumatism, arthritis, hay fever, and most allergies.
