Negative ion generator

Background

Negative ion generators are electrical devices that create charged particles called negative ions, resulting in "ionized air."

Negative ion generators are marketed to improve health by reversing negative ion depletion. They also claim to filter out smoke, dust, viruses, and bacteria from the air.

People use negative ion generators for hay fever, asthma, depression, flu, and many other conditions, but there is not good scientific evidence to support these uses.

Negative ion generators are not regulated by the US FDA. Don't confuse negative ion generators with ozone therapy. These are not the same.
There isn't enough reliable information to know if negative ion generators are safe to use or what the side effects might be. They might release small amounts of ozone into the air, but it's not likely to reach toxic levels.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if negative ion generators are safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.

Effectiveness

There is interest in using negative ion generators for a number of purposes, but there isn't enough reliable information to say whether they might be helpful.

Dosing & administration

Negative ion generators are electrical devices that can be purchased online. They are marketed to "ionize" air, and also filter out dust, smoke, viruses, and bacteria. They are mainly used for the treatment and prevention of respiratory infections. But there isn't enough reliable information about their use. They also aren't regulated by the US FDA.
