As of 2009, the negative ion generators used are still undergoing multicenter phase II clinical trials.

A small workshop produced pendulums for dowsing and a line of negative ion generators.

An ion generator emits a stream of electrons into the air.

However, some ozone generators are manufactured with an "ion generator" or "ionizer" in the same unit.

The Bionaire 1000, for example, combines an ion generator with an electrically charged filter.

Negative ion generators work according to a similar principle.

The agreement with the Advisory Council was natural resources for barastatic filters and atmospheric ion generators.

"With the research her team has done, Chryso had the data to prove ion generators would only aggravate the situation."

Several types of swift heavy ion generators and irradiation schemes are currently used:

But Luz beckoned him to follow her behind a bulky ion generator before anyone noticed them.
