![]() Thus, more work should be done to further improve NAI release by new methods or devices so that NAIs could be more widely used for air cleaning. On the other hand, strong evidence had shown the roles of NAIs in high-efficiently reducing particulate matter (PM) concentration. Here, we have carried out a comprehensive reviewing on NAIs. However, some controversial results or comments have been reported for the beneficial effect on humans/animals or on reductions in bacterial densities. In the meantime, various new technologies were developed and used to further improve NAI generation and reduce the release of its byproduct ozone. Now, NAI generators are widely available for home or industrial uses. Negative air ions (NAIs) have been discovered for more than 100 years. The system may be used to freshen indoor air and reduce PM concentration in addition to enriching oxygen content and indoor decoration at home, school, hospital, airport, and other indoor areas. This is a new NAI generation system which releases a huge amount of NAIs under the PEF treatment. Finally, we have reviewed the plant-based NAI release system under the pulsed electric field (PEF) stimulation. Experimental data showed that NAIs could be used to high-efficiently remove PM. Particulate matter (PM) is a major air pollutant that affects human health. ![]() Reports also showed that NAIs could help people in relieving symptoms of allergies to dust, mold spores, and other allergens. The presence of NAIs is credited for increasing psychological health, productivity, and overall well-being but without consistent or reliable evidence in therapeutic effects and with controversy in anti-microorganisms. Here, we have carried out a comprehensive reviewing on the effects of NAIs on humans/animals, and microorganisms, and plant development. Negative air ions (NAIs) have been discovered for more than 100 years and are widely used for air cleaning.
